These snow showers & squalls are moving thru fast, the air column is dry and the surface temps are near 32 degrees. Some lucky spots might get a quick trace or dusting :).

Yea we had some higher returns right over midtown and the result on the ground was nothing more than flurries.

5 inches? I meant heaviest at one time. It was a white out with snow blowing everywhere in wind. could barely see woods behind apartment

I was asking in general how much snow LI had for the total season, although especially after all of the blizzards over the last 2 years it's just odd to think that so far in the entire winter, a single snow squall brought the heaviest snow at one time to parts of the area.

Its not really hard to believe. None of the snow this winter has brought visibilities down like that and had that heavy of snow here at any time. The event 3 weeks ago had 4 inches, but was light the whole time/

HPN dropped down to 1/2SM as the thing went through. Looked like M1/4SM near Byram on our live camera at the height.

Yeah we were definitely under 1/2 mile vis for a few minutes across the river in Nyack. "heavy" dusting id call it lol

I would've thought that the late January event would've had more than light snow... the radar showed 20-30 dbz bands over Long Island at times with that storm, while the radar had these squalls around 28+ dbz when they moved into Long Island.

Not all 28 dBZ snow is alike. That event had graupel, which radar beams will have a higher reflectivity from. Also, there was alot of melting and mixing going on at the radar beams height so some of the snow then was bigger in size also creating a higher reflectivity. This snow squall that we just had was loaded with snow, huge flakes and small ones alike and blowing around.

That makes much more sense... thanks for the explanation. I thought it had something to do with the flakes but didn't know exactly what it was.
