Hurricane Agnes

WWA issued for the I-95 corridor counties - Also a SPS for fog around the area that have some snowpack. Currently below freezing here at 29 with dp 28,

Almost every MLK day (and the actual date varies but is the "3rd Monday" of the month) there is either an arctic blast and/or some kind of wintry event. It's like that "first week of December" type of pattern.

Although i prefer the short-range models this close to the event, the 12z Euro is tracking with the NAM for a possible repeat (with the coastal apparently coming further west enough to throw frozen at least to the I-95 corridor).

Back edge is approaching and am down to SN- but up to 1.5" with a measurement. Definitely unexpected here but I had a hunch and had put my "Polar Shield" windshield cover on and flipped up the wipers yesterday anyway. Snow is starting to slough off the cars and temp has been holding at 33 with dp 32.

Go on and do a Jeb Walk while you're at it!

Well this has over-achieved. Coming up on an inch here, streets and treated walks have caved. Temps are still marginal but ground has chilled. Currently 33 with dp 32.

12z surprisingly holding the line.

Currently getting SN but it's having a hard time sticking here in NW Philly. It refreshed the dusting from earlier that was almost gone so there's that. Might be approaching about 1/4" so far so will see if it chills the ground enough as the heavier band comes in. Temp is 34 with dp 30.

The 6z 3k NAM and EC are throwing a few inches at the Philly metro area.

Have a dusting of snow now, although I think there was/is a snow/rain mix out there. The temps have actually been rising here since midnight, which was my low today, of 32 and it got up to 36 before the precip started. Currently light snow and 35 with dp 26.

My last below freezing low was on Tues. (1/6) with a 29. Yesterday's low 37 and this morning's low was 39 here in NW Philly. Made it up to 53 yesterday but "only" 51 today and current temp is 42 with dp 35.

Looking at where that 0C line is set up N/W of Philly metro. "Traditionally", there has been some "event" around mid-January, around MLK day, so will see which way the temps go when we get there!

It was soup out there although it has now suddenly mostly lifted IMBY within the past half hour or so. My earlier vis. had to be no more than about 100 ft several hours ago. Made it up to 42 yesterday after a 29 low, and am currently at 39, after a low so far of 37.

So far have a 1/4" coating from snow that happened between midnight and 3 am and it's currently SN- and 21 with dp 15. My temp actually bottomed out at 20 just after 1:30 am.

Down to SN- and flurries and measured 3/4" from that squall dump! Temp currently 28 with dp 27. The rest of Jersey and down into central Delaware under the Warning -

And BOOM! White out! ETA temp down to 29 and falling, dp 27.

Was getting virga but finally have big flakes. Temp 34, dp 27.

SSW lofted for Philly Metro, New Jersey, and Delaware - That band looks like it means business!

SSW now lofted for immediate Philly Metro, as well as in Jersey & Delaware - That band looks like it means business!

Snow Squall Warning lofted to counties N/W of Philly - Will see if that holds together to reach Philly. Currently 33 here in NW Philly with dp 26.

And the cold front (with the wind), is coming through now. Made it up to 51 just before 1 pm and temp is now falling rapidly and down to 44 at post time. Picked up 0.33" of rain today with the prefrontal precip.

I just went up a degree. It has been hovering around 32/33 for hours and whatever frozen was sitting on/in my weather station rain gauge spout, has begun to melt and tip the bucket (at 0.07" at post time). Had bottomed out at 23 just after 2 am and am currently at my high of 34, with changeable skies (have had sun pop in and out today). Have been watching that precip field but have had nothing but virga here when the sun wasn't out.

Ended up with 0.30" of compacted graupel and sleet, coated with some freezing rain. Temp has been hovering around 27 for the past couple hours but finally ticked up to 28 with dp 26. Have been watching some narrow stationary band, extending from south central NJ to NE NJ, just sitting and I guess snowing.

Doesn't seem to be doing anything here in NW Philly except maybe some FRDZ, with about 0.3" of a crust of graupel/sleet/ice. Temp currently 27 with dp 25.

You missed the glacial January 1977, I think still the coldest on record here in Philly, back in the days when temps would go below zero more frequently (KPHL hasn't gone below zero for a low since 1994). I remember the walks were literal sheets of ice and the bus route that I took to high school that went up a little hill under train tracks, could not get up it so people had to get off the bus and walk up to the top and then get back on (the route has eventually modified decades later to avoid that hill). Salt truck just came through! Yay!!
