usedtobe Posted December 5, 2013 Share Posted December 5, 2013 Then looks like iciness... IAD is still below freezing 06z MON around 30... BWI right at freezing and DCA 31 or so The ice igonna be the bigger story though temps around the city will be marginal enough that the roads will probably more wet than icy. Untreated roads in more rural area to the west may be a different story though if it precips hard, usually car traffic and latent heat will keep them more wet than icy when the temps are around 30. Of course tree limbs or power lines could still mess things up. Link to comment Share on other sites More sharing options...
DDweatherman Posted December 5, 2013 Share Posted December 5, 2013 First thoughts Around 1-2" for Baltimore, 2-3" possible for locations such as DMW (Westminster), snow starting around 9-10am Sunday SW-NE. Up to 4 inches around JYO possible. Ice .15-.25" around 95 including MTN, BWI significant ce storm looking more likely according to latest guidance, even though snow could still hang on a bit longer. FDK .3-.5" ice accumulation down to JYO. Heavy icing to CHO, some locations getting up to .6" ice. Will have more and for more locations overnight.

If there's an inch of snow then the roads will be mostly wet and slushy already. It's awful tough to build ice on streets once they are messy. IF there is a period of decent zr near the cities it will be mostly pretty to look at and not be a major problem for travel. Except for the sidewalks. Verbatim I think xray techs are going to be busy sunday night. haha Link to comment Share on other sites More sharing options...

Although...it's a dead end street that barely gets traffic lol. So close to the fall line here but I always tend to be just cold enough to hang onto frozen precip a bit longer.
