No mention of sleet in the DC metro ZFP at 333pm

LWX going warnings now ETA - watches still for NE parts of the CWA

Pretty nice closing by the 3km NAM hours 54 to 60

It's interesting because it goes back to heavy snow at 45. If rates are heavy enough, even if there is a slight warm nose, can it be more rimed flakes?

Ripping snow EZF north at 09z

It can only snow... in the Twilight Zone

Snowing in DC metro at 05z Monday on 18z NAM

18z NAM definitely moving south through 14... let's see if it continues You can see it if you toggle the radar map on TT

RNK moved everyone into warnings as well

https://www.wpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=qpfhsd Afternoon winter disco from 237pm

RLX issued warnings for their zones bordering the LWX CWA just now

@MillvilleWx I'm going to assume another conference call tonight for upgrades to warnings in tomorrow mornings package for PHL/AKQ/LWX/CTP?

I posted the snow squall warnings in the jan 3 thread btw. Cold weather advisory replaced wind chill advisory

geez 183 for you guys

Well that escalated quickly

gets sheared out looks like IMO

12z CMC is a big hit -- all snow DC metro... prob EZF as well

800mb is barely over the line FWIW, everything else is 0c or lower @nj2va shows it better above

I would posit that as long as the precip doesnt get too light, it should remain snow since the "nose" is only a few tenths above 0c
