Wetbulbs88 Posted December 11, 2019 Share Posted December 11, 2019 9 minutes ago, eduggs said: This event was elevationally dependent as expected because of the slope of the thermal front. As is typical, surface cooling lagged mid-level cooling substantially. So elevated areas changed over and began accumulating much sooner than lower areas. And lower/coastal areas had only a brief period of accumulating snow when temps. were marginal. The problem with the snow maps isn't an issue of "sticking" with "warm ground." The issue is that the algorithms tally up all modeled "snow QPF" and display that total. Snow accumulation is different than total modeled precipitation in frozen form. Moderate snow sticks at 33 or 34F with dense overcast. Truly heavy snow sticks at almost any realistic temperature. But even steady light snow typically requires <33F to accomplish more than coating the cars. And the vast majority of snow obs. are light in any given winter.

binbisso Posted December 11, 2019 Share Posted December 11, 2019 1.5" here. 3" for the season so far. Looks like a winter wonderland here. If anyone lives in the Bronx take a drive through Pelham Bay Park on Pelham Parkway heading towards City Island what a beautiful sight this morning 1 Link to comment Share on other sites More sharing options...

Wetbulbs88 Posted December 11, 2019 Share Posted December 11, 2019 Radar has been pretty unreliable so far this year. Snowing harder than it has all year here but sitting at the back edge of a 'light-to-moderate' band 1 Link to comment Share on other sites More sharing options...
purduewx80 Posted December 11, 2019 Share Posted December 11, 2019 Any of the brighter echoes moving through the city now are indicative of the better snow growth with forcing near 500mb. We went from white rain to large dendrites and moderate snow here in Bed-Stuy over the past 15 minutes. Moderate snow at Central Park now too. 1 Link to comment Share on other sites More sharing options...

Model analyses and short-term forecasts of vertical velocities are one way (RAP/HRRR especially), but they're subject to model depictions being correct. RAP analyses are used in the SPC meso products - check out the winter weather and upper air sections for the relevant info. The 12Z OKX sounding showed no dry air issues and had the dendritic growth zone centered near 500mb. So any parcels lifted from below into that layer will give you the better snow growth. 700mb (or likely just above this) frontogenesis is doing the trick now. 1 Link to comment Share on other sites More sharing options...

I can't speak for your specific location, but surface temps. were definitely an issue (as expected) for many locations in the area based on official and unofficial obs.
