Eskimo Joe Posted November 25, 2013 Share Posted November 25, 2013 That's such a large area for the possibility of an inch of snow and sleet and tenth an inch of ice. It seems like the Winter Wx Adv. is the "cover your butts" product from NWS...always in such marginal situations. Then again it's for parts of DC Area where they can't drive in 65 and partly sunny.

Ian Posted November 25, 2013 Share Posted November 25, 2013 I doubt we see 50s. Thats always seemed like a reach to me. i've been skeptical but now all models show it so who knows. i would guess the cold air will fight at least a little since it's hard to scour even in ideal conditions, so would lean east on the zone of warm to cold.

I am assuming that I-95 will be the battleground for the "cold" and "warm" areas... I could see places like Ashburn being 42 and Waldorf 55 Link to comment Share on other sites More sharing options...
Ian Posted November 25, 2013 Share Posted November 25, 2013 euro still ~2.5"+ most spots east of the mtns -- maybe .5" less than last night. Link to comment Share on other sites More sharing options...

Ian Posted November 25, 2013 Share Posted November 25, 2013 Does it have nasty dry slot? not really. maybe just offshore and across coastal NC.. but even those spots mostly get 1"+. pretty solid 2"+ from fl panhandle to maine. Link to comment Share on other sites More sharing options...

Scarlet Pimpernel Posted November 25, 2013 Share Posted November 25, 2013 It seems like the Winter Wx Adv. is the "cover your butts" product from NWS...always in such marginal situations. Then again it's for parts of DC Area where they can't drive in 65 and partly sunny. I have to laugh at this because it's so true!! Or seems like it many times. The advisory expanding to the immediate north and western counties outside the District isn't a total surprise. It may be a "CYA" in part. However, I recall that the criteria for advisories for times around rush hour in the metro areas were lowered a couple years back with the knowledge that many people on the roads equals a potentially bad situation no matter how little snow or ice falls. So I don't totally blame LWX for putting that out there, especially with holiday traffic this week, and many people are probably hitting the roads tomorrow.

The holiday traffic is probably a big factor there. Link to comment Share on other sites More sharing options...
WxUSAF Posted November 25, 2013 Share Posted November 25, 2013 So now we are hoping the front end over-peforms So, Euro's down for 1" of snow on the front and 0.5" on the back? ALL IN. Link to comment Share on other sites More sharing options...
Scarlet Pimpernel Posted November 25, 2013 Share Posted November 25, 2013 The holiday traffic is probably a big factor there. I believe that is true. At least for them issuing this so far in advance. At the same time, if there were no holiday this week I think they'd still probably issue an advisory for early tomorrow, but just probably at a later time.

Scarlet Pimpernel Posted November 25, 2013 Share Posted November 25, 2013 So, Euro's down for 1" of snow on the front and 0.5" on the back? ALL IN. Yeah!!! 1.5" snow before we hit December, and that's probably a third or so of what I got all last season!! Link to comment Share on other sites More sharing options...
