FEB 13th Pre V-Day Storm Part II

Lightly snowing and sleeting roads are getting slushy

Officially snowing in NYC, everything is getting covered!

Approx location of 850 line. This continues moving south over the next couple hours. It is about where it was forecast to be, maybe even a bit south, at this time.

Latest GFS 06Z Run. Im hoping to get 4-6" out of this. Love that it shows a almost a foot, but 4-6" is where my head is at. Real sharp cut offs for I84.

Bill that radar is dead on accurate. Can you provide url? thanks!

I agree heehaw. 4” imby would be a double into the gap. 6” a home run. Anything over 8” and this storm is a grand slam (and a coup for the GFS lol).

It is the RadarScope app. Precip Depiction setting.

30.6 here and heavy snow. Did not expect to wake up and see this. The power of lowered or in this case almost no expectations.

Haven't gone out to measure but grass completely covered and plow just went through. Eyeballing, as Doc would say, at least 2.5 inches so far. I'm about 12 miles south of 84 so not sure how sharp the cutoff is there. Looks to be snowing at a fair clip all the way up to Poughkeepsie on radar.

Incredible that it still shows my area with a foot. The next 7 hours must really get going or this is gonna bust for this area. I'm reading some up north already have 3 inches on the ground. Very nice!

I still think GFS is overdone - maybe by a few inches in the max areas. But if this really did achieve 1-2” per hour rates, would only take 4 hours of that heavy snow (which we may get from 7-11 am) to get 4-8” on top of whatever comes before or after that.

Heavy snow 31.8 about 1/2" OTG.

It's a good sign when the scope of WSW's increases in the AM update.

I'm a big fan of this signature on the h5 trough. That's going to push in a lot of instability inland.

30.4° and snowing moderately here 12 miles south if I84. Intensity down in the last 15 minutes.

4.0 inches officially as of 5:15 am. Don't know what happened between midnight and five but wish I'd been up to see it. This has already exceeded my greatly lowered expectations from last night. Plows already been through and street covered again.

Dropped to 31.5 with heavy snow. I expected to have to fight above freezing surface temps. Pleasantly surprised

Same here. Thought at 5 am I’d wake up to 34* wet pavement and light snow. Instead 32* moderate snow and everything is snow covered.

There are times when the antecedent air mass is less important and less need for the big banana H which I usually look for to get sig snow. Track and n/s interaction can compensate for that and this case looks to be doing so.

Gonna have to snow very hard in next five hours for Brooklyn my to get 3”this storm is fast

Surface low 992mb on the Delmarva. Deepening rapidly.

Deer Park
33 with some light snow and sleet. A light coating on the grass and cars..

They just closed schools for the day in Edison.

This is good placement for us. Probably explains a bit why the cold air has intruded a little faster than expected.

The wind direction around that Low due to its placement is NNE. That can’t be underestimated either.
31* here, moderate Snow, NNE wind 10 mph, gusts 21mph.

Radar is impressive and expansive with this system.

Heavy snow 31.2/31.0 winds gusting to 25 maybe 30 mph. Have to measure but approaching 1.5" seems reasonable.

It's going to probably look blizzard like at times as this storm cranks.

Same here CP, 4 inches, 30 degrees moderate snow.I had the call of nature around 3:45 and there was an eyeballed 1 1/2 inches OTG then so must have started around 2 am.Sure looked like we were going to be scrooed on this yesterday with the rapid southern shifting.So, with that being said:

Snowstorm check on nowcast day:
1) Is there snow on the ground? Yes, 4 inches CHECK
2) Does the radar look juicy? At least 4 or 5 hours of 1/2 plus per hour rate CHECK
3)Cold weather for a week ahead for a good snowpack and a refresh Clipper or two? CHECK
Let's see if we can get to 6 , a victory for us considering the dire straits of yesterday.

Hope the South and East crew get their 8 plus radar looks very good for them as well.

This storm has become a forecasting nightmare. Just when it looked like we were going to have an under performer with all the cutbacks on snow totals yesterday afternoon/evening, lo and behold the storm has seemingly done a head fake and the meso models have been bumping north overnight. Quicker closure of the ULL and negative tilt of the trough can work wonders.
