Cool down coming

Two more warm days on tap before temperatures settle back into the 70s with lower humidity.

Today:  Mostly sunny, warm, highs in the low to mid 80s south, upper 70s along the coast, near 80 north.

Tonight:  Clear, areas of fog toward dawn, lows in the upper 50s to near 60 south, near 50 north.

Tomorrow:  Partly sunny, chance of showers and thunderstorms in the afternoon, some could be severe, highs in the mid and upper 80s south, low 80s north.

Tomorrow night:  Showers and thunderstorms taper off in the evening, becoming partly cloudy, lows in the mid 50s south, upper 40s north.

Thursday:  Lots of sunshine, cooler, highs in the mid and upper 70s south, mid and upper 60s north.

Discussion:

We are still under the influence of high pressure here in New England today.  This will allow for plenty of sunshine today and another days of warm temperatures.  As we head into tonight and tomorrow there will be a cold front approaching the region.  Ahead of this front, dew points will get a bit higher making for a humid day tomorrow, starting with patchy fog tomorrow morning.  The front will approach the region during the afternoon hours, which is prime timing for showers and thunderstorms to develop.  The orientation and motion of the front will be conducive to most areas seeing the showers and thunderstorms.  The front will be moving from northwest to southeast.  Normally cold fronts move in directly from the west or from a southwesterly direction, this typically keeps most of Southern New England free of showers and storms.  A southerly wind brings stabilizing air in from the Atlantic.  Tomorrow the winds will be more westerly ahead of the front, so the stabilizing effect won't be as prominent.  Depending on how much sunshine we see before the front arrives will determine how unstable the atmosphere will be.  So just a heads up for tomorrow, I'll elaborate more with tomorrow's update.

Beyond tomorrow, we'll have another stretch of dry weather but this time temperatures will be cooler and there will be little to no humidity.  An upper level low will settle in over the Northeast keeping conditions cooler, but we should stay mainly sunny.  This looks like it will last right into the first half of the weekend.  There could be a few showers around on Sunday, but we'll have to wait and see if that feature is still in the forecast models in the coming days.

Thanks for reading!  And remember, tomorrow is the start of hurricane season.

Severe Weather threat today

I'm expecting some strong storms across New England, particularly across the interior of New England.

Today:  Partly to mostly sunny, showers and thunderstorms will develop during the middle of the day across Central and Eastern NY and push eastward.  Small hail, high winds, heavy rain and slight chance of an isolated tornado or two.  Warm and humid, highs in the low to mid 80s.

Tonight:  Any showers and thunderstorms taper off during the evening, becoming partly cloudy, lows in the 60s south, 50s north.

Tomorrow:  Partly sunny, isolated showers and thunderstorms possible in the afternoon, highs in the upper 70s to lower 80s.

Tomorrow night:  Mainly clear, lows in the 60s south, 50s north.

Sunday:  Partly to mostly sunny, warm, highs in the mid to upper 80s.

Memorial Day:  Partly sunny, slight chance of an afternoon shower or thunderstorm, highs in the mid to upper 80s.

Discussion:

There is likely to be some rough and tumble weather developing this afternoon across portions of New England.  Nothing like what the middle of the country has had to deal with fortunately.  A low pressure system will swing a weakening cold front through the region this afternoon.  Along and ahead of this front showers and thunderstorms will develop and press eastward.  Western New England into VT, Southwestern NH northeastward into Western Maine are spots that are under the greatest risk.  Further south, timing of the fronts arrival and southerly wind will bring cooler air into Southern New England will limit the threat of showers and thunderstorms, especially the severity of those storms.

Storms will dissipate during the evening hours and then we are in for a beautiful weekend.  There might be enough instability left behind tomorrow to kick off a shower or storm tomorrow afternoon, but the activity will be widely scattered.  Other than that, we are looking at a good deal of sunshine and mid summer like temperatures here right through Memorial Day.  Monday may also give us a stray shower or thunderstorm, but again, isolated in nature.

I might not be updating this every day over the weekend.  If the forecast changes toward the negative, meaning more unsettled weather than I originally expected, I'll update the blog.  If you don't see an update, expect the status quo.

Thanks for reading!

Yesterday continued...

Another near perfect day on tap for New England though a few isolated showers and storms are possible far inland.

Today:  Plenty of sunshine, warm and a bit humid, isolated showers and thunderstorms in the afternoon across the interior of New England, highs in the low to mid 80s, upper 70s coast and north.

Tonight:  Partly cloudy, patchy fog toward morning, lows in the 60s south, 50s north.

Tomorrow:  Partly sunny, slight chance of a shower or thunderstorm in the afternoon south, showers and thunderstorms likely in Central and Northern New England, some could be severe, highs in the 80s south, near 80 north.

Tomorrow night:  Maybe an evening shower or storm, otherwise partly cloudy, lows around 60 south, 50s north.

Saturday:  Partly sunny, isolated showers and thunderstorms possible inland, highs near 80.

Sunday/Monday:  Partly to mostly sunny, dry, highs in the upper 70s and lower 80s.

Discussion:

We do have a low pressure system approaching, but this shouldn't have too much of a negative impact on the holiday weekend.  It may be an issue for today and tomorrow, but after that we are generally in the clear.  Most of New England is going to stay dry today as the low and it's cold front will only get close enough to affect Upstate NY and possibly Western MA and VT.  Showers and thunderstorms will begin to develop in the early afternoon across Western and Central NY, which will then push eastward.  By the time the line of storms reaches New England then sun will be on it's way down and the storms will be running out of energy.  Because of that, we really won't see much activity here today.

Tomorrow is a different story as the storms will initiate closer to or in New England.  Based on the set up of the atmosphere, the activity will be mostly confined to Western, Central and Northern New England.  Southern areas will likely stay dry due to southwesterly wind bringing some cooler air in from the Atlantic near Long Island.  This will have stabilizing effect on the atmosphere over Southern New England.  Elsewhere, showers and thunderstorms should pop up during the early to mid afternoon and then push off to the northeast.  High winds, small hail, dangerous lightning and heavy rain are expected in some of the stronger storms.  Can't rule out an isolated tornado, but weather conditions should not be overly conducive storms of that nature.

Once we hit the weekend conditions will calm down.  A stray shower or storm will still be possible on Saturday, but beyond that we should be in the clear.  The low pressure system will lift further off to the north and east leaving high pressure in control.  We will have a good deal of sunshine and warm temperatures right through Memorial Day.

Finally!

Our weather is finally turning around, for the time being, enjoy it while it's here.

Today:  Lots of sunshine, highs in the mid and upper 70s inland, near 70 along the coast.

Tonight:  Mainly clear, lows in the low to mid 50s south, 40s north.

Tomorrow:  Partly sunny, slight chance of a shower or thunderstorm, especially in Western New England, highs near 80 south, mid 70s north.

Tomorrow night:  Partly cloudy, lows in the low 60s south, 50s north.

Friday:  Partly sunny, again the slight chance of a shower or thunderstorm inland, highs in the lower 80s south, 70s north.

Discussion: 

After the cold front moved through last night, we are going to be clear of any drizzle, fog and mist for at least a week.  We are in between storm systems today and this is going to be provide pleasant conditions to the region.  Inland areas of New England will have the best weather today.  A seabreeze will develop along coastal sections which will keep temperatures from getting too warm this afternoon.

As we head into the day tomorrow, another storm system will be moving closer.  However, it never really moves into New England.  The low pressure system will move off to the north and west of New England into Quebec and then will stay there for a few days.  This is a pretty good spot for a low to set up shop.  In this position our winds will stay out of the south and west, which is a warm wind.  The downside to the low being there will be some instability in the atmosphere.  Fortunately, it doesn't look like a washout any day over the next 6 days or so.

This low will introduce the chance, generally less than 40%, of showers and thunderstorms developing with the heating of the day.  This starts tomorrow and will really only be a problem for the interior of New England.  Western MA, VT, Central and Northern New Hampshire will have the highest chances of seeing showers and storms.  Overall our weather will be quite nice right through the upcoming holiday weekend!

Bye Bye Fog and Mist

Today should be last day we see this mist, drizzle and fog for at least 5 days, probably longer

Today:  Morning clouds and fog then some hazy sun, showers and thunderstorms possible this afternoon.  Some storms could be severe with high winds, small hail and heavy rain, especially in Southern New England, highs in the upper 70s to low 80s.

Tonight:  Showers and thunderstorms come to an end in the evening, becoming partly cloudy, lows in the upper 50s to near 60 south, 40s north.

Tomorrow:  Partly to mostly sunny, highs in the upper 60s to low 70s.

Tomorrow night:  Mainly clear, lows in the 50s south, near 40 north.

Thursday:  Partly sunny, slight chance of a shower or thunderstorm, highs in the 70s.

Discussion: 

Say good riddance to the ocean influence that we've been dealing with for the past 2 weeks.  A cold front is moving toward New England today, the combination of this and a strong sun will burn off the clouds.  Once those clouds burn off, it will be warm and humid today and as a result, we should see a few thunderstorms develop.  Atmospheric conditions are conducive to severe thunderstorms today, but these strong storms should be isolated in nature.  Most of this activity should be restricted to Southern New England and probably south of the Mass. Pike.

The front will clear the region this evening, taking the showers and thunderstorms with it.  After that, we are looking at much more seasonable and pleasant conditions, even if there will be a few showers around at times.  Wednesday will be nice, plenty of sunshine and mild, coolest temperatures along the coast.  Thursday should also be generally nice, though a few showers and storms may develop across the interior thanks to a low pressure system approaching from the west.

Further out into the week and into the weekend, it looks like it is going to be OK.  The low pressure system that is approaching on Thursday will be around, but not significantly impacting the region all the time.  Temperatures will be warm and it will be a bit muggy as well.  There are going to be a few showers and thunderstorms around at times too.  I'm not going to get too in depth beyond Thursday, but right now, the weekend doesn't look like a washout by any means.

Still getting better

I'll admit, it was much nicer yesterday than I thought it was going to be, I expect that trend to continue today.

Today:  Mostly cloudy, a few breaks of sun at times.  Areas of drizzle this morning with the chance of showers and thunderstorms, especially this afternoon, highs in the 60s to near 70.

Tonight:  Mostly cloudy, patchy drizzle possible, lows in the low 50s south, upper 40s to near 50 north.

Tomorrow:  Mix of clouds and sun, showers and thunderstorms possible, highs near 70 north and south.

Tomorrow night:  Partly to mostly cloudy, lows near 50 south, low 40s north.

Sunday:  Mostly cloudy, maybe some AM drizzle, highs in the low 60s south, upper 60s north.

Discussion: 

After a much improved day yesterday, I'm expecting a bit more improvement today.  We are of course dealing with a marine layer that moved back in after the sun went down last night.  However, as the sun gets higher in the sky, it will start to burn off the low clouds, drizzle and fog.  It should start in Southern NE and then work it's way north.  Places in Northern New England haven't suffered as much from this and will likely break out into the sunshine first today.

However, as a result of the heating from the sun, showers and thunderstorms will likely develop during the course of the day.  Wouldn't be surprised to see a few severe thunderstorm warnings issued today either, and with all the rotation from this upper level low, a stronger storm may be able to produce a weak, very weak tornado.  The chances of this are pretty low, but I feel this setup would be the most conducive to tornadoes that we will probably see this year.  We would need some pretty strong heating from the sun to make this happen though.

Patchy fog and drizzle will likely try to come back in tonight after the sun goes down, but not to the same extent that it did last night.  Even more sunshine should be seen tomorrow and then we will be probably see more showers and thunderstorms develop again.

Sunday is going to be an interesting day.  The forecast models are all over the place with what is going to happen.  Another storm system will be approaching New England on Sunday.  Some of the models try to bring the fog/mist/drizzle back in.  I'm not so sure that is going to happen.  We may see some in the morning, but I think the southwesterly winds that will develop and the strong sun will beat this back and we should see some sunshine.  Temperatures may be a bit cooler than what we will have on Saturday though.

Look for more showers on Sunday night into Monday, but temperatures will be far warmer than we had all this week.

Thanks for reading!

Better weather is coming, just not yet...

Still under the influence of a marine layer and I'm not going to "wish cast" this front out of here before it's ready to go.

Today:  Cloudy, patchy drizzle and more showers, especially this afternoon, highs in the upper 50s to low 60s south, near 60 north.

Tonight:  Cloudy, showers possible, lows in the 50s south, upper 40s north.

Tomorrow:  Mainly cloudy, showers possible, patchy drizzle as well, milder, highs in the low to mid 60s.

Tomorrow night:  Mostly cloudy, chance of showers, lows in the low 50s south, upper 40s north.

Saturday:  More clouds than sun, showers and isolated thunderstorms possible in the afternoon, highs in the 60s north and south.

Discussion:

More of the same here in New England, though it is gradually getting warmer.  We are still under the influence of a large area of low pressure in the Eastern United States.  There is a frontal boundary that is still just to our south that has continually provided an easterly wind.  This wind coming in off the ocean has kept temperatures down and brought showers and drizzle into the region.  Fortunately, this low is weakening and starting to shift.  As a result, the easterly wind isn't as strong and the cloudiness is not as dense.  This will allow temperatures to get a few degrees warmer today and tomorrow as well.

However, I don't want to seem too optimistic here.  I want to see some sun as much as the next person, but this cloudiness and air mass in place is going to take some time to move out.  Saturday will probably seem like the nicest day we have had all year, but we still probably won't see much sunshine and rain is a good possibility.  It really won't be until Sunday where we are likely to stay generally dry, though how much sun we will see remains to be seen.  I guess I've been burned too many time by trying to rush the low clouds, fog and drizzle out of New England in the past and this time I'm not going to do that.  I hope I'm wrong and that we see some significant improvement tomorrow.  At this point however, I'm expecting Sunday will be the day that we finally break through.

Next week looks much much better.  Southwesterly flow though the lower levels of the atmosphere will keep our temperatures mild.  Looks like a cold front will slide through around Tuesday that may bring some showers and storms, but we will dry up right after that front.  So like I said in the title, better weather is coming, it just requires bit more patience.

Spring time

This weather is terrible.  You know it, I know it.  Also, my apologies on the lack of blog recently, took some time off.

Today:  Cloudy with drizzle and rain showers, highs in the 50s.

Tonight:  More rain and drizzle, lows around 50 south, 40s north.

Tomorrow:  More of the same, showers and drizzle, highs in the mid 50s to near 60 south, low 50s north.

Tomorrow night:  Cloudy with the chance of showers, lows near 50 south, 40s north.

Friday:  Continued cloudy, chance of showers, a bit warmer, highs in the low 60s.

Discussion:

I'm like the rest of you, I'm ready for some sunshine.  However, Mother Nature is not quite done giving us a healthy dose of New England Springlike weather.  The weather feature that is responsible for all of this is a large low pressure system across the Eastern US.  This is a "cut-off" low pressure system.  This means that is a removed from the overall flow of air around the Earth.  It has no driving force to move it, so it is just sitting there, spinning.  It will continue to rotate showers and cool air into New England through the rest of the work week.

It is gradually losing strength though.  Over the next couple of days, temperatures will be slowly warming and the amount of precipitation we will see will be lessened.  Instead of the low actually moving away, it will essentially start to fill in.  The basic dynamics of the atmosphere function as follows:  "Air moves from high pressure areas to low pressure areas."  Normally low pressure systems can "stay alive" by steadily moving, slowing down the process of filling in.  However, when a low gets cut off, it doesn't have the luxury of staying ahead of the air trying to fill up the low spot in the atmosphere.

So much of the same through the day on Friday.  Conditions should improve on Saturday and I expect to see some sunshine.  This however will likely lead to more rain.  A moist layer at the surface and a quick heating from the sun will lead to instability.  This should produce some downpours and a few thunderstorms on Saturday afternoon.  Sunday is going to be the best day, can't rule out an isolated shower or two, but with high pressure build in, it should inhibit lift in the atmosphere.

We just need to make it through a couple more days and then we should be rewarded with a few days of pleasant conditions here in New England.

Thanks for reading!

Beautiful Friday

A downright gorgeous day today will be followed up with a decent weekend, for the most part.

Today:  Lots of sunshine, mild, highs around 70 south, mid 60s north.

Tonight:  High clouds build in, lows in the upper 40s to near 50 south, low to mid 30s north.

Tomorrow:  Mainly cloudy, a few breaks of sun, chance of showers and maybe an isolated thunderstorms, highs in the mid 60s north and south.

Tomorrow night:  Decreasing clouds, lows in the upper 40s to near 50 south, 30s north.

Sunday:  Partly sunny, highs in the low to mid 60s north and south.

Discussion:

We are in between storm systems today and this is going to supply some nearly perfect weather for New England.  Plenty of sunshine through some high thin clouds and temperatures a few degrees above the normal.  Unfortunately this will really only last for today as another system is approaching.  As we head into the day tomorrow, a low pressure system will be passing to our southeast.  This will be close enough to add some instability to the atmosphere.  As temperatures warm up throughout the day, showers and perhaps isolated thunderstorms will develop.  The good news is that not everyone will have wet weather tomorrow.  It's not going to be a wide spread event, so I expect some places to see little or no rain.  Look for the rain to develop toward the middle of the day and then taper off during the early evening hours.

Conditions will improve for Sunday as the storm system pushes further out to sea.  There will still be a few clouds around, so we won't have full sunshine, but in general it will be a pleasant day.  Right now it looks like the weather we will see on Sunday is what we can expect for much of next week.  There is one feature we need to keep a close eye on however.

The low pressure system that will pass by to our south tomorrow might try to retrograde back toward New England early next week.  If that is the case, the forecast will change considerably.  If it does move back toward the west, we could be looking at drizzle, fog and mist with cool temperatures for a few days during the middle of next week.  The forecast models generally have a tough time forecasting these scenarios, especially when it is more than 4 days out from the current time.  It would be nice to have a Spring here New England with a few of these retrograding storms.  I'll keep an eye on this over the next few days.

Thanks for reading!

Looking mostly dry

Cooler air aloft will help kick off showers across New England today and then maybe some more rain on Saturday.

Today:  Limited sunshine, chance of showers, especially across the interior of New England, highs in thd 50s south, upper 40s north.

Tonight:  Partly cloudy, maybe a rain or snow shower north, lows in the upper 30s and low 40s south, low 30s north.

Tomorrow:  Partly sunny, slight chance of a shower north, highs in the upper 60s south, around 60 north.

Tomorrow night:  Partly to mostly cloudy, in the upper 40s to near 50 south, 30s north.

Saturday:  Mostly cloudy, chance of a showers and maybe an isolated thunderstorm, highs in the low 60s both north and south.

Discussion:

After the cold front moved through yesterday, we are left with a cold pool of air over our heads.  This will lead to some instability today as any sun we see during the first half of the day will heat up the surface and that warm air will quickly lift into that colder air.  Remember, warm air rises.  This will create more clouds and tap into the remaining moisture in the lower levels of the atmosphere to create rain showers.  I wouldn't be surprised if there are a few snow showers across the higher elevations of New England today either.  This includes tonight, where I think surface temperatures may get cool enough for snow to reach down into the valleys of Northern New England.

The cooler air will dissipate tomorrow, though a few isolated showers may still be possible across Northern NE.  It will be much warmer tomorrow as well thanks to a change in wind direction at the surface, from northwesterly to a west or southwest wind.

Saturday remains a bit of a tricky forecast.  There will be a low pressure system passing to the south of New England.  It looks like it gets close enough to trigger scattered showers across the region, particularly Saturday afternoon.  For now, I've gone heavy on the cloudiness.  If we get more sunshine than I expect currently, it will be warmer and I think our chance of showers and thunderstorms will increase with the more sunshine we get.  The more heating we have, the more unstable the atmosphere will be.

Beyond Saturday, condition looks dry with seasonable temperatures until late next week.  Temperatures in the 60s to low 70s, slightly cooler in Northern NE with a good amount of sunshine.

Thanks for reading!

Ugly now, better for the weekend

A cold front will push through New England today bringing rain and then chilly air for tomorrow.

Today:  Cloudy, showers likely with the chance of a few thunderstorms, highs near 60 south, low 50s north.

Tonight:  Mostly cloudy a few showers still possible, lows in the upper 30s to low 40s.

Tomorrow:  More clouds than sun, showers possible, cooler, highs in the low 50s south, upper 40s north.

Tomorrow night:  Partial clearing, lows in the low 40s south, 30s north.

Friday:  Partly sunny, maybe a few showers in Northern New England, highs in the low 60s south, 50s north.

Discussion:

A cold front with slowly sweep through New England today.  This should provide just about everyone with some rain at some point today.  There could also be a few embedded thunderstorms along the cold front today, none are expected to reach severe levels.  The front will clear the region late tonight, but unfortunately that doesn't mean we are done with the unsettled weather.  The low pressure system associated with the cold front will become stationary to the northeast of New England over the Canadian Maritimes.  This will hold cooler air in the region and also will keep the atmosphere unsettled enough for more showers.  It won't be a steady all day rain, but will be more scattered in nature.

Friday that stalled low will begin to move out into the North Atlantic and this will help improve our weather here in New England.  Southern and most of Central New England will have a pleasant day on Friday with some sun and seasonable temperatures.  Northern areas may still be under the influence of that departing low so a few isolated showers may develop.

This weekend looks generally nice.  A low pressure system will be passing south of New England which is causing a bit of uncertainty in the outlook.  As it stands now, we should stay mostly dry this weekend with at or above normal temperatures.  As a matter of fact, if we stay dry this weekend, our next real threat of wet weather won't be until late next week.

Slow moving storm

Hope everyone enjoyed their weekend and then breaking news last night and this morning!

Today: Sun this morning then increasing clouds, highs in the low to mid 60s both north and south.

Tonight:  Mostly cloudy, slight chance of a few showers, lows in the 40s.

Tomorrow:  Cloudy, showers possible, especially north, highs in the 60s south, upper 50s north.

Tomorrow night:  Continued cloudy with the chance of rain showers, lows in the 50s south, upper 40s to near 50 north.

Wednesday:  Cloudy with rain likely, highs near 60 south, 50s north.

Discussion:

We'll squeeze one more nice day out today before conditions begin to deteriorate.  A slow moving storm system is moving toward New England and it will affect our weather throughout the middle of the work week.  As we progress through the day today, clouds will start to build in from the southwest.  Eventually we won't see much sun by the time it sets this evening.  After that, we really won't see the sun until possibly the weekend.  It depends on how everything develops of course.

Over the next few days I'm fairly confident about what will happen.  A battle zone between warm and cold air will set up across the interior of New England late tonight and will remain in place through the day on Wednesday.  Tonight and tomorrow will be cloudy and damp, though most of the rain showers should be over Northern and Central New England.  On Wednesday, the center of the low pressure will be ride northeastward along that battle zone and will help to push it through New England.  This will also bring enhanced chances of rain to the entire region, making it the wettest day of the week.

Beyond Wednesday, the forecast is a bit fuzzy.  The low pressure system looks like it is going to stall just off to our northeast late in the week.  The problem is how far east the low makes it, does it retrograde and how much of the energy rotating around the low makes it back into New England.  If it pushes further out to sea, our weather will be nicer sooner.  If what I'm seeing is correct, our weather will be a bit unsettled until we reach the weekend.  Right now I'm expecting a mainly cloudy with a few showers right through the day on Friday.  More on this throughout the week.

Thanks for reading!
