A bit better Sunday with highs in the low to mid 50s. A bit better Sunday with highs in the low to mid 50s.
At least the B's and the Sox were bright spots on this damp and dreary April day.  Rain and onshore breezes killed any hopes of a warm-up today as temperatures flat lined in the middle 40s.  Rain amounts weren't impressive, but a couple tenths of an inch to a half an inch of rain was enough to keep the ground wet and the puddles on the roads.

After some lulls late this afternoon and early this evening, a renewed batch of showers, even a few embedded rumbles of thunder, move in late evening and overnight tonight with another batch of instability that has to work through.  With this batch, the air mass overall is cold enough that wet snow may mix in across the higher terrain of Southwest New Hampshire, Southern VT and the Berkshires, and perhaps even the hilly terrain in northern Worcester County. Yikes! The timing of the renewed showers start in the 8-10PM time period in Worcester County, and mainly after 10PM east of 495. 

The overnight showers taper by Sunday morning, however, the low level moisture is tough to completely scour out.  That means a lot of leftover clouds, a few morning sprinkles and an isolated afternoon shower is still possible.  I know, I know, doesn't sound great, but we'll get some dry hours in the mix too, and wind winds turning north to northwest, temps run in the 50s instead of the 40s. So at least it's a bit better.

Monday and Tuesday feature dry weather from start to finish, but still on the cooler side.  Mid to upper 50s Monday and near 50 Tuesday.

Wednesday and Thursday feature cool onshore winds and rain moving back in thanks to an approaching low from our southwest.  With a big high to our north, the pattern is slow to move, and that's why these onshore wind days and rain events can be so persistent and carryover multiple days.  This one could dump 1-2" of rain across the area.

By Friday, we should be able to get that low to our northeast, allowing for land breezes and an attempt at drier weather to end the week and go into the weekend.  The issue late in the week, and perhaps next weekend, is the fact that the air aloft is awfully cold looking, and that can create instability with the day time heating and trigger scattered afternoon showers to develop in the afternoon.  I left the rain drop in the 7day for Friday and Saturday, and that's for that potential of an afternoon shower or two.  Also not the sun icon too and the temps that warm into the low to mid 60s.  

Have a good Sunday and enjoy the rest of the weekend.
