Hurricane Agnes

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!

That's cause you are nestled in the hills up there. I remember driving by there on the way to Niagara Falls and the area is really pretty (IMHO). Some stations near me have reported 40+ mph gusts as a note. The winds have really picked up here now. Temp is a chilly 38. ETA - At post time, KLOM reporting 18 mph sustained & 41 mph gusts - https://aviationweather.gov/adds/metars/index?submit=1&station_ids=KLOM&chk_metars=on&hoursStr=2&std_trans=translated&chk_tafs=on KPHL has 33 mph sustained, 45 mph gusts - https://aviationweather.gov/adds/metars/index?submit=1&station_ids=KPHL&chk_metars=on&hoursStr=1&std_trans=translated&chk_tafs=on KPNE has 26 mph sustained, 45 mph gusts - https://aviationweather.gov/adds/metars/index?submit=1&station_ids=KPNE&chk_metars=on&hoursStr=1&std_trans=translated&chk_tafs=on

Heard on the KYW traffic report that there was a power outage around Castor and Frankford Ave. PECO reporting 4800 outages and map is showing a big outage in the area near Port Richmond in the city and in Cheltenham (around La Mott), plus scattered all around the Montco outskirts of NW Philly. I think this is just getting started. Hope power holds where I am. https://www.peco.com/Outages/CheckOutageStatus/Pages/OutageMap.aspx Temp here is 36.

Hearing the winds starting to howl. Temp back up to 45 and partly cloudy.

Looks like it's on the CWA doorstep. Temp still slowly dropping. Down to 43. Interestingly enough, the sky started clearing and the sun was trying to come out just before it set.

Briefly hit a high of 45 about an hour ago but it's back down to 44. The front is still back near western PA so not sure if we end up with a non-diurnal temp surge overnight or we're done rising before the front comes through (the sun sets in a little under 20 minutes).
