A Brighter Finish to the Workweek...
Did you see it? That elusive fireball in the sky revealed itself for a few short intervals this afternoon...ironically, the longest interval of sun occurred on the Cape. Tomorrow the intervals will be longer and more frequent but clouds will still be pesky. The large ocean storm has now swirled well offshore but it has left behind plenty of moisture and it will be hard to scour out of the lower levels of the atmosphere due to the onshore wind direction. That moisture will be condense into stratocumulus clouds over the next couple of days due to a slightly unstable atmosphere...basically even though the surface low is moving away, it's parent cold pool of air at 500mb is still hanging back over us (cyclonic flow), that will create rising surface air that cools and condenses. So to some up these next couple of days will be much better with intervals of clouds and sunshine. Highs will range from 65-70 inland to around 60 at the coast and a little cooler than those ranges on Friday.
I mentioned last night that the weekend was looking iffy...it still is. It appears that the ridge located just to our west producing some fabulous weather will be beaten down a bit by a retrograding cut-off to our north in Eastern Canada. This will send a backdoor front through the area most likely Saturday afternoon (but it could be sooner). So showers will once again return by the second half of Saturday. The front will likely stall in and around Southern New England on Sunday at the same time the next cut-off (slow-moving storm) will be working through the Appalachians, out ahead of it a flow of warm moist air will develop this flow will crash right into the front keeping the front very active with convective type showers and rain which will likely last for days.
