High pressure in control

As the title states, high pressure is in command and this will keep our weather quiet through the day on Thursday.  Unfortunately, it will be chilly today and breezy at times.  Wind chill values will be quite cold today.  Bright sunshine is expected however, so if you are in direct sunlight, sheltered from the wind, the sun will feel warm.  Look for high temperatures only in the 20s today.

Tomorrow and Thursday, tempeatures will warm a few degrees each day, we'll hit the mid to upper 30s tomorrow(more melting, yay!) and then into the 40s in Southern New England on Thursday, probably still in the 30s for Central and Northern New England.  Skies should remain mainly sunny right through sundown on Thursday evening.  Our attention then turns to a storm system approaching from the Appalachains.

The forecast models, after several runs showing a similar solution are starting to deviate from each other now.  This of course makes it very difficult to forecast what is going to happen.  However, the one model that is showing it colder, hasn't been doing a very good job this winter.  The model that is showing a warmer solution has been pretty solid.  I'm going hedge toward that warmer solution for now. I still expect much of New England to get a period of wintry precipitation.  The further south you are, the shorter this period will be.  Places in Northern New England may get a significant ice event from this system.

On the other side of the spectrum, if the colder situation develops, we'll see mainly snow, but the majority of the precipitation will stay south of New England.  It would be a plowable snow in Northern MA into VT and NH, but not a crippling event.

Now if the warmer solution develops, as I have stated for the last few days, flooding will be concern, particularly in Southeastern MA and RI.  Time will tell and I'm monitoring closely.

We probably will see a light snow on Sunday as a weak disturbance pass through.  Temperatures after this system passes through on Friday will drop off to chilly again and probably will remain chilly until the beginning of next week.

Stay tuned and tell your friends about this blog!  Thanks for reading!
