Hurricane Agnes

The precip had pretty much ended here although something is looping around. I did see where the WWA was dropped here in Philly too. Currently overcast and 36.

I think the problem is figuring out the meso scale probabilities where they overdo the convection that could draw in and self-generate cold air that would up the chances for a switch to all-frozen. What often kills that scenario is warm air that filters in well above the surface due to the (relatively) "warmer" ocean temps and unless there's a big arctic high to the north, it just can't get the cold air down through the whole column.

I've been watching the rain/slow line slowly moving off the coast with the blues and purples filling in over your area. Was wondering if that was translating into real snow or what.

Still getting a light but cold drizzle here and whatever snow fell this morning is gone. Am up to 0.17" of liquid today and temp is currently 35. Have been watching that wide band in Jersey pivoting and backing in from the NE as the low moves east but am not sure if a band would make it this far west before the storm moves away.

The snow mixed with rain and is now all light rain/drizzle here for the past hour with temp @34. Melting underway. Got about 1/4" slushy coating on the car.

Had a rain/snow mix a couple hours ago (picked up 0.08" rain overnight) that dusted the car and colder surfaces. Now have SN- with a coating on those colder surfaces (including the grass), with marginal temps at 33.

Looks like today/tomorrow may be a nowcast storm. So far picked up 0.07" of rain overnight and the temp is hovering not much above freezing at 34 here.

I was in the 34 - 35 temp range much of the day until later this afternoon when the temps started creeping up to 37, which is my current temp (with light drizzle/mist). Have picked up 0.53" so far today but didn't see any flakes or ip.... at least yet. Have also been semi-following the wild model gyrations trying to deal with the coastal and where it sets up. I expect there may be some surprised folks tomorrow if this all verifies. Even Amazon seemed to realize something was up when when they sent out another delivery truck and I received a couple packages about 30 minutes ago that were due for delivery tomorrow that they went on and delivered today (about 15 minutes after I received today's expected deliveries)!

You're right - that WSW was put up by Binghampton (the point and click is acting wacky) -

Mt. Holly lofted a WWA further south and converted the Leigh Valley Watch to a Warning...

You're basking more than me. I'm currently at 35 near the 400ft asl range. Some of the lower elevation sensors around Springfield & Cheltenham townships are at or barely above freezing and the ones in those same areas near the tops of all these hills are running warmer - in the 38/39 range.

As of the 11 pm update, Sebastien is now post-tropical -

5 pm update (not much change other than forward motion and expected to become post-tropical some time tomorrow) -

Flakes are coming down pretty heavy - still pancake but coating the cars and grassy areas. Temp down to 37.

Just got a text from my sis in Wyndmoor to alert to the big flakes. Literally 5 minutes later they started here in NW Philly with some pancake flakes. Already up to 0.84" rain today (0.14" yesterday) and a temp of 38.

5 am update and it continues to strengthen (plus a slight delay in prog for it going post-tropical) -

Better late than never but a 5 pm Sat. update (although it has strengthened over the past couple days, it is expected to become post-tropical tomorrow and dissipate next week) -

5 pm update (now moving N and slowed a bit) -

Was trying to post earlier but there were apparently some issues with Amwx.... 5 am update on Sebastien -

After a high that barely cracked freezing yesterday (33), I bottomed out at 23 this morning, a degree "warmer" than yesterday morning's low of 22. Currently 29 and overcast.

Couple record and tied record lows this morning (from AFD Climate section) -

Currently at 22 with single digit dps (currently @ 7 here), and still a bit more than an hour before sunrise. That's some arctic air!

I think last year the snow was a couple days later, on 11/15 - 11/16/18 (and I actually got 4.5" of a combo of frozen then).

I was a senior in college at UMASS/Amherst then. For some reason I don't remember much about it because usually the eastern side of the state got the bulk of the nor'easter snows and this particular one happened about a week after Karen Carpenter had died, so that seemed to stick with me more than the weather at the time. I used to work at the radio station on campus and did the Friday drive-time news, so remembered reporting that (also remember watching the M*A*S*H finale a couple weeks later too ). They usually cleared the snow out pretty quickly on campus, although the snowball fights would be epic before that happened. I think there was more hullaboo about that blizzard down here than up there.
