Its a shame we don't have more users from Prince George's county. Some of those areas are getting 2"/hr rates under that narrow band. Lake-effect-esque.

I'm in Davidsonville and the band just got here. We were getting shafted all morning with nothing more than pixie dust and now it's dumping. Everything is finally turning white. Wouldn't say 2" per hour though...

32/29 -SN, maybe 0.3"

One thing some of the models got wrong was surface temps...pretty much all of immediate DC metro is 30-32...even DCA was 33 last OB....The idea that we were going to be 35 all day has not come to fruition.

The next 3-4 hours should have the best snow growth. It will still pulse but there should start being an increase in "fatty" reports incoming.

Nice conglomerated dendrites in the band in northern MoCo. Jumped to over an inch quickly. Video attached.

Heavy rain mixing with some sleet in Richmond. Safe to say unless cold air from the west is pushed in, we are probably done for. It was fun. Maybe more next time around.

As the upper level support to your west rotates through I'd be pretty suprised if it wasnt all snow. No idea if it will be accum snow but the soundings down there are all snow west of RIC and only borderline over the city.

Truth. All guidance tended colder leading into to onset so they were a little late but didn't miss it. Guidance has busted to warm a lot over the last couple weeks but we only pay close attention when snow is involved. Lol
