Mesoscale Discussion 0156
   NWS Storm Prediction Center Norman OK
   1158 AM CST Sat Feb 19 2022

   Areas affected...CT...RI...MA...NJ...southeast NY...eastern
   PA...southern portions of VT and NH...northern portions of MD and DE

   Concerning...Snow Squall 

   Valid 191758Z - 192200Z

   SUMMARY...An intense snow squall will continue to accompany an
   arctic cold front as it moves rapidly east this afternoon, resulting
   in a brief period of blizzard/near-blizzard conditions.

   DISCUSSION...Composite radar imagery continues to show an intense
   snow squall accompanying a strong cold front that was moving rapidly
   east (near 40 kt) across portions of the northeast U.S. at 1755z. 
   Surface observations and time-lapse camera imagery show rapid
   deterioration of visibility along with accumulating snow as the snow
   squall moves through, with several METAR observations reporting
   brief blizzard conditions.

   In the presence of strong and focused ascent along the front through
   low-level convergence, low/mid-level frontogenetic forcing and
   rapidly cooling surface temperatures, the majority of latest
   high-res guidance supports a continuation of the snow squall as it
   moves east with the cold front through much of the remainder of this
   afternoon.  A brief period of heavy snow along with wind gusts of
   35-45 mph will result in blizzard or near-blizzard conditions as
   visibility is quickly reduced to at or below 1/4 mile.

The temp here is up to 43, so very unlikely we will see any accumulation from the snow squall. RGEM changes it over to rain by the time it gets here too, so that's possible. Too bad the temps are not a little bit colder to make this snow squall event more interesting.

I was at 40 before it started…

Light to low end moderate snowfall during the squall. Nothing heavy enough to accumulate. Sunny again.

As much as I loathe winter I’m a snow squall fan.

If you’re in CI, the squall line is still west of NYC
