Am now a few minutes past sunrise and have been holding at 12 here in NW Philly since about 5:30 am. Dp is fluctuating between -2 and -1. Opened the front door briefly and am noting that same very high hazy deck of thin cirrus and that may have kept radiational cooling down.
"Snow on snow" is an interesting concept missing this season (so far).
My dp has crashed to below 0 and my "high" today did end up being 35 just before the arctic front blew through here around 5:30 am.
Currently down to 21 with dp -3 (although it has dropped to as low as -5 briefly).
Literally missed being under the heavier blobs by a couple miles. Down to a broken cloud deck with a few flurries and a dusting. Temp stabilizing a bit at 29/dp 22.
It was like a downsloping warming and as the front hit with the winds, the temp has been dropping. Temp now down to 30 w/dp 24.
Edit - now down to 29 and continuing to fall.
Am guessing that is riding along the arctic front. I was surprised that it was still at or above freezing here but then there are clouds that kept the radiational cooling down.
KYW Traffic report already reporting the snow up around I-78 (Justin Drabick).
Temp here is 33 with dp 24.
Yeah am now back to overcast with that, with an occasional break as a reminder that the sun is still up.
Currently at my high (so far) for the day - 39, with dp 19. That might be the warmest it gets through the first part of the weekend.
That's better than the GFS this winter with those long-range storms that didn't verify.
Almost not a cloud in the sky* save for some contrails here and there.
(*although looks like there may be a fuzzy deck of very high cirrus that has still allowed a "blue" cast to shine through for a faux blue sky )
Currently 37 and mostly sunny with dp 16.
Phil came through!
Mt. Holly had some historic data on him -
I dropped down to 25 as a low this morning and it's currently partly sunny and 27 with dp 16.
Well all gone - and before it hit 32.
And it is currently 32 here with dp 24 and the clouds have returned! <Jim Nabors voice> Surprise surprise surprise.
As I had somewhat expected (but wasn't definitive about), I apparently didn't even have to wait to go above freezing... the snow on the east side of my car's windshield has already started to disappear, and fairly quickly at that (about 1/3rd gone)!
Sun out, clearing rapidly, and now partly cloudy. Temp is up to 30 with dp 24. As soon as the temp goes above freezing, whatever is out there will go poof.
Went out with the ruler and got 0.2" - and was actually examining what fell and it looked like quite a bit of small graupel mixed in because the surface coating had piles of tiny foam-bead-looking stuff mixed in that was definitely not sleet (was softer).
Am currently at my low of 29 (so far) this morning and it's overcast and somewhat misty, with dp 24.
Car topper 1/4" here. Not much on the grass but just some of the coldest surfaces.
Currently SN-- and 30 with dp 24.
Below was when some of the heavier stuff came through...
