Very nice agreement between the GFS and the NAM re: total storm precip amounts. GFS shows 1"+ from DC-Annapolis and straight eastward toward Dover.

it basically matches the 0z euro as well.. stripey dc/balt

Agree... NAM though did have a thin stripe of 1.25-1.50 though on it.. so it might be a bit overdone... NAM/GFS/EURO agree on around an inch QPF of just about all snow DCA/BALT... not really sure what LWX is thinking right now still having WWAs... and i wonder what OPM will do...

Most of us already received 3-5 inches this morning. Suck it up and deal.

had some mixing so my total was around 2.5", but I ain't complaining

my office, 6 miles SE of my house, had less and a friend from Severna Park had 1/2-3/4"

everyone else should understand that the precip will be caused by the upper level dynamics, no dynamics, no precip; more importantly, it will be those dynamics that will also cool the atmosphere such that one hour you're drizzle at 34 or 35, then the precip/dynamics move in and you're 32 with heavy snow

the further north, the cooler you will be but all the models put the heaviest strip of precip between BWI and DCA so the extra qpf should result in a uniform snowfall for the area, all things considered

not liking the drop off in northern md but it is probably wrong anyhow.

I have 5 inches on the ground and still seeing moderate snow. At the rate it's going I may wind up with 6 or 7 by the time it gets here. You never know where these bands will set-up, but if they stay south I can survie becasue I still will wind up with near a foot anyway, anything else is just bonus. :popcorn:

...RAPIDLY DETERIORATING CONDITIONS FOR THE MID TO LATE AFTERNOON

AND EVENING RUSH HOUR COMMUTE...

AFTER A BREAK IN PRECIPITATION THIS MORNING...ACCUMULATING SNOW

WILL OVERSPREAD THE AREA THIS AFTERNOON AND EVENING. A MIX OF RAIN

AND SNOW WILL QUICKLY CHANGE TO ALL SNOW DURING THE AFTERNOON AS

IT BECOMES HEAVY. THE PERIOD OF HEAVY SNOW WILL COINCIDE WITH THE

LATE AFTERNOON AND EVENING RUSH HOUR COMMUTE ACROSS MOST OF THE

REGION...INCLUDING THE WASHINGTON DC AND BALTIMORE METROPOLITAN

AREAS. CONDITIONS IN SOUTHERN MARYLAND WILL DETERIORATE AROUND

SUNSET AS PRECIPITATION CHANGES TO SNOW.

THE HEAVY SNOW WILL REDUCE VISIBILITIES BELOW A QUARTER MILE WITH

SNOWFALL ACCUMULATION RATES AT TIMES OF 2 INCHES PER HOUR. THIS

WILL PRODUCE DANGEROUS TRAVEL CONDITIONS DURING RUSH HOUR. SNOW

WILL MOVE OUT OF THE AREA BY MIDNIGHT.

I think we're looking at a start time closer to rush hour, which means folks are not going to get out of work early. That means the highway carnage this evening will be epic. If you can weasel your way out of work this afternoon, do so.

I'm leaving the city at 3:00. I don't want to be anywhere near a road when the boom starts.

I wrote something to Jason lobbying for upping are amounts and we crossed e-mails. It sounds like I was lobbying to the choir and he's already pretty excited. I'm not sure what amounts he'll end up with but think it likely he'll nudge them some based on the very intense snowfall rates being forecast by the nam and gfs,

You are normally the most conservative guy here (and for good reason). What the heck is LWX smoking?
