1.2" total for DC with ~0.5" falling between 12z and 18z and another 0.2" between 18z and 00z.    It's a good run for DC..probably the best we can hope for given the setup.  

 

if we blend GFS/NAM soundings, we probably flip in DC around 9 or 10....but will probably waste snow for a bit until we get to 34....it's a cold air/precip race

mitchnik I live a stones throw from you, on rt 175 east columbia and I.m really not expecting to see much accum either, despite all the talk about temps and rates, if it snows in nov, i,m happy., Wishing your family ,gods best blessings peace and prosperity.

 

Am also in East Columbia.  I've noticed a big difference in accums (usually declining) driving from Columbia to BWI area after many storms.  Personally, I also don't see much chance of accums on grass, decks, etc. until late afternoon or early evening -- if then -- unless we get some great rates earlier.

all you have to do is get on Rt. 100 and drive east from Rt. 104 and it's all downhill....in more respects than one!

I have low expectations here...my desire is to change the landscape a bit to create a nice holiday mood. An inch or two on the grass will do that. Anything more including street accumulations is a bonus but is highly unlikely. I sure hope most on here get to see some white love lay on their yards. Good luck all

I'm right near Rt. 100 and Rt. 103. I've seen a snow difference in just the 2 miles from my neighborhood to 95. So yeah Mitch--got that right! BTW. Local TWC says 3-5 inches? Hmmmm.

I think we busy high under heavy rates and the ground is covered, including streets. This doesn't include the immediate downtown DC area until very late tomorrow afternoon. 2-5 inches in the 95 corridor. Temps have fallen nicely overnight

I honestly don't have a problem if this busts low (or completely) because just the fact that we see a Miller A at this point in the season bodes well for the next 3 months

regardless, good luck and Happy Thanksgiving to all in case I can't see through my tears tomorrow     lol

Yes, if a Miller A pattern can establish itself from the funky jetstream it gives good odds of snowier Jan and Febs. Temps seem to be pointing to rain events in Dec.

37 winters here and it's really only useful to pay attention from Jan 5 thru March 5, if you like snow.

Even the euro Temps are concern at this point. Those of us to the west stand a better chance. But I think this is a white rain storm for basically everyone. I will be happy with 2 inches on the grass before thanksgiving though.

Aren't Euro temps usually a degree or two on the high side?  Seems they tend to come down as we approach an event.  Maybe that's just with CAD...
