Coldest Night Yet...
Did you all hear that yesterday was opposite day? That's why when we said today was supposed to be mostly sunny we really meant mostly cloudy! Moisture got trapped under a low-mid level inversion and spread out underneath it providing a stubborn stratocumulus layer that took most of the day to finally burn off under the weaker November insolation. Now we are clear and ideal radiational cooling conditions are setting up and by morning almost all towns will be in the mid 20s! Radiational cooling will also create a nocturnal inversion that could trap moisture tomorrow morning and we could have a bit of ground fog form. Models handled today's cloud cover terribly and I am very weary of patches of clouds forming again tomorrow under similar weak inversions.
We are still looking a phasing on Thursday and a soaking rain to develop on Thursday morning with the heaviest in the afternoon. As mentioned last night the track looks to hug the coast so warm air will get into most of central and eastern New England so it will be all rain and probably around an inch.
Again, the baroclinic zone or breeding ground for storms where the temperature gradient is greatest won't get very far offshore so we will likely have lingering colder rain showers on Friday too.
The upper level trough traverses New England over the weekend with a slight chance for a shower or flurry on Saturday (especially early) then some late November cold air works in for Sunday with highs in the low to mid 40s.
