Hurricane Agnes

If it gets really convective in the right spot and ramps up the rates, you just need a couple hours of that before it goes flying off to the NE.

I'm teasing you. Even Mike chimed in that they might be "too high". I think some of this is due to the traditional hanging of a hat on the Euro, which the past couple years has not been the best (maybe some upgrade did it in) and a knee-jerk dismissing of the NAM (which has gotten a bit better the past couple seasons).

I think this is the first Winter Storm Warning for Philly (county) the whole season (I usually archive the watches/warnings) - This would pretty much be Philly school-closing criteria. And as a sidenote, I have been LOLing at Kamu talking Ralphie off the cliff.

Getting some flurries the past 15 minutes or so. Some remnants have been passing over ("heaviest" in quotes about 10 minutes ago). Temp is still 32.

The temp remained at or above 32 all night. Looks like I have about 1/4" of a sleet/ip/snow mix on the car windshield (nothing on treated surfaces) but the gauge ticked up to 0.32" of liquid (I think much of yesterday's snow had pretty much already melted in the hole before this started). There was light rain here about an hour ago. It's interesting to look at the archived nexrad images back to midnight to see the rain/snow line literally wavering along I95. Currently 32 and DZ.

Am I seeing things or is that a HECS in NY & NE. It's like Colorado's typical spring snow has been transplanted to the east coast. Must be all sorts of convective feedback or something.

Has FV3 become the "new NAM" (even if much of it might include sleet, but still....)? Must have been a brain transplant from the NAM to the new GFS, meaning we can now start saying we were FV3ed.

There was one little last blob headed my way about an hour ago but it evaporated so my final for storm #1 was 2.90". Cleared off the car and popped over to the supermarket and noticed the snow was about average consistency here - not really powdery nor heavy/wet but fortunately lightweight. Wanted to get it off the car in case storm #2 ends up with enough rain in there to transform the almost 3" of snow into a concrete paste. Currently 33 and mostly cloudy but with a broken deck and sun trying to come out. And boy is that March sun doing its work. The snow is sloughing off of cars that haven't been cleared yet.

Since he moved back east and lives in VA, he mostly posts in MA, although he still pops in with obs from his parents' house in Ewing, NJ.

I think because storm #1 actually started "March 1st" (morning) and storm #2 is also supposed to start March 1st (this afternoon/tonight). So there were storm #2 disco mixing in with storm #1 obs.

Measured 2.9" but there is one little blob that appears headed this way shortly. Temp is up to 30 with some pixie dust snow at the moment.

Is this going to just be a discussion thread or an obs thread or both? I think that is also part of the confusion.

The movement of this has been interesting to say the least. It started out with a general W --> E motion then shifted to a SW --> NE movement and has now started a NW --> SE movement. So with that, the "back edge" keeps basically staying stationary near me and I still have light snow. It was to the point where places in the city south of me had nothing and now it has filled back in over the city proper. Temp is still creeping up ever so slowly (although still 28 - technically 28.2).

Snow still hanging on here. Flakes have gotten bigger again and am somewhere between SN- and SN. Temp 28.

Down to very fine flakes and SN-. Will wait until that is done for final measurement. Temp crept up to 28.

Was looking at some of the archived data on my GRLevel3 program (images posted below) and saw it started here IMBY around 3 am. A heavier band started setting up around 3:45 am, and sortof ballooned on its way east. The back edge is approaching and it's still snowing lightly but with bigger flakes that are adding to the accumulation. Temp still holding at 27.

Yeah but what happened was that many of the roads were not done (in some cases, not pre-brined) so with the antecedent cold, they have been snow-covered and the usual idiots think they are in a Suburu commercial blasting through the snow (but failing).

Just came back in from measuring. 2.0" on the nose. Snow rate is varying from SN- to SN but with the temp at 27, it is still steadily accumulating. Even though the WWA was up since last night, it seems that people are being surprised by this. There are accidents galore being reported. Maybe because the previous events were mix and this is all snow - at least here in the Philly area and immediate 'burbs. Plus there has been a lot of hype about the Sun/Mon storm so this one seemed to have been minimized.

Some LSRs have 2.5" - 3" in central Montco and north and central Chesco (1 includes Paul's report). Has lightened up a bit here to SN- but still steady. Temp holding at 27.

Have just over an inch here with SN. Temp is 27. Seems to be a narrow band of the heavier precip.

WWA lofted for the southern 1/3rd of the CWA -

Just read the article at AccWx - https://www.accuweather.com/en/weather-news/meet-the-man-behind-the-mic-american-weather-icon-says-farewell-as-illustrious-51-year-career-comes-to-a-close/70007560 IIRC he used to live here in Philly and went to the junior high school a couple miles from me. Loved his wacky and corny puns and would look forward to the days when he did them. He was unique at the time given the fact that most local radio/TV media used non-met on-air staff to read the forecasts, with someone behind the scenes actually coming up with them. Nowadays, "broadcast meteorology" is a major with its own degree. Wish him well and hope he enjoys his "on-air" retirement!

A whole row of those are pretty cool. There have been a ton of accidents reported this morning with that light precip. The roads have been chilled to below freezing so it has been an ice rink on them. One of my sisters just texted that there was a 20-car pile-up on 309 near where she is in Wyndmoor (probably in the vicinity of the Paper Mill Rd or Flourtown exits) and they had to close it. Anyone going out in the SE Montco/NW Philly area please be careful!

Temp 31 and was on the southern fringe of something that blew by leaving a very light 0.1" sugar dusting of snow on only the coldest surfaces - notably the car - sometime between 3 - 4 am. Was able to grab a nexrad image of some of it -

Here is the actual tweet - and closeup of that map (this was as of/just before the tweet, which was 2/17/19) - There is an interesting hole in southern Delaware too, somewhere along an area between Milford and Lewes!
