Could you imagine if we got a legit Dec 5th event? Something like a regionwide 3" - 5" fluff storm? This place would crash from excitement.

The temp crash during the day Sunday on the euro is pretty impressive.  FDK is 32 at 4am and 18 at 1pm with a gusty NW wind.

We are talking about an event that is less than 36 hours away in the medium/long-term thread.  And Sunday maybe missing north or south.  And about how the snow gods hate certain spots on the map, and reward everyone else but them with snow.  And how it might be warm for Christmas like it was in 1965, but not for long.

60 at Christmas is now closer to 35..................  What a thrill!!!!

If this Sat/Sun event pans out - we get pretty lucky with the timing of the onset. It’s honestly not that cold when precip starts (euro actually at 33° for the beltway). Cmc is rain. If this was during the day it might have been even tougher.

It’s never easy.

Crazy how that came true a month out (albeit with smaller amounts)

 Psuhoffman said something that stuck with me, we've always been right on the line with events that would go in our favor. Now we seem to be just on the wrong side of that line, instead of just on the right side.

If this weekend pans out, I will be pretty satisfied. Usually we spend December talking about snow chances in Jan and Feb. Now it's like having multiple threats in Jan but in Dec. I like the trend so far. Always a chance to over perform.

If DCA gets 1.1" of snow or more in the next few days, it will be the snowiest December for them since Dec 2009... 16 years.

Dang my bad.

On topic - I think the extrapolated NAM was gonna be pretty nice.

There has been some talk about a torch leading up to Christmas.

The White Christmas fans would have loved Christmas 1969 in Augusta County.

I recorded 12 inches of snow with a high of 24 and low of 14. 

Lets do it....................................

go to 18z nam for the composite. Right at 84 you see the explosion of snow in the east.

 

that link defaults to 12z
