Pleasant but a bit cool

We'll have a relatively nice weekend coming up, but temperatures will be a bit cooler than the last few days.

Today:  Partly to mostly sunny, slight chance of a shower inland, highs around 70 south, mid 60s north.

Tonight:  Mainly clear south, partly cloudy north with a few isolated showers, lows in the 40s south, mid to upper 30s north.

Tomorrow:  Partly to mostly sunny, highs in the lower 60 both north and south.

Tomorrow night:  Mainly clear, lows in the low 40s south, upper 20s and low 30s north.

Sunday:  Mostly sunny, highs in the low 60s north and south, upper 50s along the coast.

Discussion:

High pressure is in control at the surface for this weekend.  It hasn't quite taken control yet and because of this, there might be a few showers across the interior of New England.  Behind the cold front that moved through last night, cooler air has moved in aloft.  As the sun heats up the surface today, this will create lift in the atmosphere and produce some cloudiness.  There is also enough instability left behind that may help to kick off a few isolated showers across the region.  It looks like most of this activity will be across the interior of New England, mainly this afternoon.

As high pressure takes full control tomorrow, the risk of showers will diminish.  We'll be left with plenty of sunshine, but slightly cooler temperatures.  Saturday will be the better of the two days, mainly because I'm expecting a sea breeze to develop on Sunday.  This will keep coastal areas a bit cooler.

Our next chance of unsettled weather will be on Monday with a cold front moving through.  Mostly just expecting showers, but a few thunderstorms might be possible.  Tuesday looks dry at this point and then Wednesday looks to be messy.  One model indicates that temperatures aloft will be cold enough to support snow, that's right, snow.  Do I think we will see snow, I'm not sure yet.  It's a possibility that some higher elevations could see some snow, but not all the models have this storm hitting the region.  Time will tell.

Thanks for reading!

Cold front passage

A cold front will move through New England today followed by what looks like a decent weekend.

Today:  Mostly cloudy, chance of showers and thunderstorms, highs in the low 70s south, upper 60s north.

Tonight:  Any showers and thunderstorms end, partial clearing, lows near 50 south, upper 30s north.

Tomorrow:  Partly sunny, maybe an isolated shower or two inland, highs near 70 south, low to mid 60s north.

Tomorrow night:  Clear to partly cloudy, lows in the mid and upper 40s south, mid and upper 30s north.

Saturday/Sunday:  Plenty of sunshine, slight chance of a shower north, highs in the upper 50s and low 60s south, 50s to near 60 north.

Discussion:

A cold front will pass through New England today.  This front is just about out of energy so I don't think we will have anything significant across much of New England as it moves through.  There were some warnings in effect across the Hudson Valley this morning in NY, but those storms are weakening and will probably just end up being thundershowers for Western New England this morning.  The front will start to get stretched out this afternoon and it will start to split.  Some energy will go north in Canada, the rest will stay south and slide below New England.  We should only have widely scattered showers and some isolated thunderstorms through the evening.

Once the front clears we are in for a decent weekend.  There will be some cold air aloft that may help to kick off a few light showers at times across the interior of New England.  Other than that, we'll have a decent amount of sun and seasonable temperatures.

Please keep the people affected by the severe weather outbreak in your thoughts today, that was one of the worst tornado outbreaks since the Super Outbreak of 1974.  So far I've seen reports of 160 tornadoes and over 180 people dead.  Staggering numbers.  Several of these storms passed over densely populated areas and many happened late in the evening when people were sleeping.  Some entire small towns in Georgia were completely destroyed.  Debris that was created and then picked up by the tornadoes were falling from the sky 50 miles from where the tornado was located.  There was debris and hail falling at the same time.  The debris was getting sucked up into the tornado, taken way way up into storm and then was blown out ahead of the storm by 50 miles!
