Sidewalks and neighborhood paved surfaces all slushy and getting snowy. Wind picking up. Probably accumulated 0.2-0.3” in my 40 min @Jebman Jebwalk
-
0.4” on the board
-
At freezing or very close now in Columbia. Ratios should jump up nicely with these rates and flakes.
-
-
Grass getting slushy. Absolutely dumping right now…
-
All snow giant flakes. My PWS (which doesn’t do great when it’s wet) has lost like 5F in the last 90 mins. But neighbors’ suggest about 34 now.
-
It’s starting. Meteors falling
-
It’s trying. Temps are definitely dropping. Come on snow, be the storm we know you can be!
-
Temps seems to be ticking down. Maybe a few flakes mixing back in.
-
My kids are getting antsier than me waiting for snow
-
Yeah it’s got to be something like that. Drizzle still with pretty respectable reflectivity
-
Radar would seem to suggest more then drizzle and yet…
-
To get accumulation, I think the first step is to increase rates above drizzle lol
-
Temp has gone back up a bit. Light rain/snow.
-
Incredible! Hellebuyck MVP
-
Damn Hellebuyck single handedly keeping the US alive
-
Most nearby PWSs down to 35 now in east Columbia. Still mostly rain. Maybe 50/50 snow and rain in heavier bursts.
-
First mangled flakes in Columbia
-
-
Temp has dropped a bit with the heavier rain but no snow flakes in sight despite my intense squints out the window
-
Question is does it just sort of flip from N/W to S/E and then stay all snow (even if non-accumulating for awhile), or does it pulse back and forth and be rate dependent during the middle of the day before a flip to snow for good mid-late afternoon?
-
Ah right, I got it backwards with the elevation scans.
-
Euro has been low for DE coastline relative to all the other guidance for awhile?
-
This is a day where correlation coefficient rare is our friend. Looks to me that is showing rain almost everywhere but the highest elevation scans (closest to IAD) are snow. So snow is melting as it falls, as we’d expect. But the highest DBZ returns south of DC right now are maybe also mixing with snow at the ground.

Final call/guess: BWI: 4.9” IAD: 4.2” DCA: 2.3” my yard: 4.6” Norrisville: 14.7”
