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!
