If anyone has or can get the Euro total snow map, please post. I know I've seen those posted before (I think), but I don't know where they come from.

Here ya go: the only two ECMWF panels that show snow accumulating, hrs. 39 and 42

EDIT_ Oops cut off the scale:

Lightest shade of blue is 2-3" in 3 hours.

I thought the reason the computer program that made the map was designed to apply the science.

I don't think Yeoman has actually added to the conversation in a few years here so don't worry about him too much.

Euro is still meh but hard to say. 6 hour increments don't help. But I think the implication is pretty clear. That there is not much moisture to work with after the changeover for the cities. A forecast for my backyard based strictly on the euro would be heavy rain mixing with and changing to snow before ending. Up to an inch possible mostly on grassy surfaces. I still like my over under of 0.5" here.

I hope your call is right, I'm still hoping to keep the dec snowfall below average if I can escape this storm. I'd hate for it us to get two sloppy little events to push us over climo. I'd like to lose on a big dog.

My memory was the GFS did.

Thanks. If that's the case here as well then you would almost have to go with the lower snow totals with the warmer GFS.

If my memory serves me right though, in the past the NAM normally had a better grasp of the temp profile but it also overdid the precip totals, though in the OCT storm it seemed to have a good grasp of the totals. I have to wonder what's different to cause this change in tendencies.

We by far have the biggest weenies in the country, myself included.

i dunno if that's true.. read some of the other forums.

that said, snow lovers are fairly content to never learn anything year to year it seems.

LWX weighs in with their afternoon AFD

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY/...

A POTENT WAVE OF LOW PRESSURE WILL PASS BY JUST TO THE SOUTH

WEDNESDAY EVENING BEFORE QUICKLY MOVING UP THE COAST TOWARD NEW

ENGLAND LATE WEDNESDAY NIGHT. PRECIPITATION ASSOCIATED WITH THIS

SYSTEM WILL CONTINUE ACROSS THE REGION WEDNESDAY EVENING BEFORE

ENDING FROM WEST TO EAST OVERNIGHT.

COLDER AIR WILL BE FILTERING IN FROM THE NORTH AT THE SAME TIME THE

STORM SYSTEM PASSES BY JUST TO OUR SOUTH. THEREFORE...RAIN IS

EXPECTED TO END AS A PERIOD OF SNOW. LATEST GUIDANCE SHOWS STRONG

DYNAMICS WITH THIS SYSTEM...BUT IT WILL BE A QUICK MOVING SYSTEM.

THEREFORE...THERE WILL ONLY BE ABOUT A TWO TO FOUR HOUR PERIOD FOR

SNOW BEFORE DRIER AIR COMES IN AND ENDS THE PRECIPITATION. THE

HIGHEST SNOWFALL TOTALS ARE EXPECTED ACROSS THE HIGHER ELEVATIONS OF

THE POTOMAC HIGHLANDS AND SHENANDOAH VALLEY WHERE COLDER AIR WILL

ARRIVE FIRST. A WINTER STORM WATCH HAS BEEN ISSUED FOR THESE AREAS.

ELSEWHERE...ACCUMULATING SNOW IS LIKELY FOR THE LOWER ELEVATIONS

ACROSS THE SHENANDOAH VALLEY...EASTERN PANHANDLE OF WEST

VIRGINIA...EXTREME NORTHERN VIRGINIA AND NORTHERN MARYLAND. A WINTER

WEATHER ADVISORY MAY BE NEEDED FOR PORTIONS OF THESE AREAS. FURTHER

SOUTHEAST TOWARD THE CITIES OF WASHINGTON/BALTIMORE AND FOR

LOCATIONS SOUTH AND EAST THE COLDER AIR WILL TAKE LONGER TO ARRIVE.

THEREFORE...ONLY A BRIEF PERIOD OF SNOW IS EXPECTED BEFORE

PRECIPITATION ENDS OVERNIGHT. LIGHT ACCUMULATIONS ARE POSSIBLE

ACROSS THESE AREAS ESPECIALLY ACROSS GRASSY SURFACES. WILL CONTINUE

TO MONITOR THE TIMING OF THE STORM OVER THE NEXT 24 HOURS. SHOULD

THE STORM TRACK A BIT SLOWER THAN EXPECTED...THEN HIGHER SNOWFALL

TOTALS MAY APPROACH THE CITIES OF WASHINGTON/BALTIMORE.

PRECIPITATION SHOULD END BY THE MORNING RUSH HOUR THURSDAY AS THE

LOW RACES OFF TO THE NORTHEAST. HIGH PRESSURE WILL BUILD OVERHEAD

THURSDAY PROVIDING DRY AND SEASONABLY CHILLY CONDITIONS.

Well maybe i should rephrase that, we have the biggest weenies who rarely get snow. At least in New England and NY they get some snow.

I'd be pretty surprised if DCA records more than a few tenths of an inch. Even if they get in a period of moderate snow for 45 minutes it would probably be a T or 0.1". IAD is another story. They got 0.6" with the October storm. I think they probably surpass that but the bust potential is still high. It seems to me the model guidance has to be pretty wrong to get an extended period of heavy snow and 31-32 degrees such that several inches could fall even in the burbs. I like the CWG map. No reason to go any more bullish than that map.
