Discussion-OBS snow event sometime between 06z Thu 2/20-12z Fri 2/21?

Good mornin all:: OBS will probably start here sometime midday or early afternoon.  Should see a nice refreshing powder per the mapping added below. or as you see it differently but snow is coming and you'll see it rapidly expand on radar during midday as the short wave approaches through Philly northeastward.

Wont surprise me that there is a short period of 3/4S- near 6 or 7PM CP and a 1/2-1" snowfall there though uncertainty exists.

Let us know if sticks to the streets this evening... I kind of think in the area described below that will be slippery on untreated surfaces sometime during the evening rusk hour, especially after sunset. Winter driving habits advised, for sure side streets.

Dendrites might increase from the typically cold thickness small flakes, briefly to moderate sized flakes this evening per modeled lift in the deeply saturated dendrite growth zone aided by cirrus seeding. 

Graphics hopefully are self explanatory including the 09z/20 NWS ensemble chance of 1" (very low a you can see) the 00z/20 SPC HREF which is optimistic for near 1" in parts of our area, 00z/20 European ensemble snowfall output and the 4AM NWS snowfall forecast.

My sister lives in Cary NC moved to get away from cold and snow like most people, however this is their 3rd event this season and they are enjoying as it's unique and not a typical year.

My cousin lives in Raleigh. Looks like they got like half an inch or so. Def a year for them.

Agree. Once you get to 3/15 that’s pretty much all she wrote, even for southern New England, minus some freak, high anomalous event. At that point you have sun angle, climo and length of day all working very strongly against you 

We had a recent March, might have been 2017 or 2018 with 4 or 5 big storms in March. We got into a pattern where we got coastals every week, but that was definitely an anomaly. One of my all time favorite storms, March 2010 was a 5" rain maker, occurring a few weeks after the snowicane.

Yep and he complained about how Norfolk got so much more than he did. He had Richmond around 8

He sucks! What years ago when I first started following him, I thought the guy was really good but then I could see that he was wrong so many times. I mean, if you're a weather forecaster, you're gonna be wrong, but he went down in flames so many times it was comical.

He was hugging the nam and ignoring the models showing much less. Anyone enough about him

The NWS has come around to Walt's thinking (which Lee Goldberg on Channel 7 agrees with, too) as their interactive point/click map now shows 0.5-1.0" north of 276/195 in PA/NJ/NY (and 1-2" in the Poconos) vs. 1/4-1/2" south of that line, even though their official map only says <1". Still pretty minor, but as the NWS said, "with cold temps, roads could get slippery especially after sunset this evening." This would apply for areas that get more than 1/2", given temps in the upper 20s. Also, the most recent 12Z mesoscale/short-term models (NAM, HRRR, RAP, RGEM), which, in theory, should do better with a minor mesoscale event like this, are all showing 0.5-1"+ for areas N of 276/195. The NWS map shows 0.5" for my house, but I'll go with a hugely overperforming 0.7", lol.

Also, for those curious, this was a big storm for NE NC and SE VA and extreme southern MD/DE, as per the map below. The VA Tidewater area got 8-12", the northern OBX got 3-5" as did the Research Triangle and Richmond areas, and extreme southern MD/DE got 4-6", while areas in western VA/NC got a fair amount less than forecast as did northern VA/MD, with DC actually shut out, as was all of NJ, except Cape May which got <1/2".  Was really fascinating to see the steep gradient across the southern half of Sussex Co, DE, going from 0 to 5" over a 20 mile stretch from NW to SE.
