Deck Pic Posted December 24, 2012 Share Posted December 24, 2012 1/9/12 redux and this air mass is much much better Link to comment Share on other sites More sharing options...
Bob Chill Posted December 24, 2012 Author Share Posted December 24, 2012 Ll cold is definitely better than I thought for so early in the evening. 28.5 in the yard under clear skies. Doubt it drops more than another degree. Obs to the n & w are colder. Good stuff. Link to comment Share on other sites More sharing options...
Yeoman Posted December 24, 2012 Share Posted December 24, 2012 I guess if it snows enough and there is still some on the ground on Tuesday then that would technically be a white Christmas...fingers crossed The official definition is at least 1" on the ground.

Solo2 Posted December 24, 2012 Share Posted December 24, 2012 Not sure why, but it is ridiculously warm in Frederick even with clear skies. Link to comment Share on other sites More sharing options...
mitchnick Posted December 24, 2012 Share Posted December 24, 2012 Not sure why, but it is ridiculously warm in Frederick even with clear skies. I noticed Martinsburg was 42 last hour I even checked to see if it just hadn't reported, but that was a current temp Link to comment Share on other sites More sharing options...
mattie g Posted December 24, 2012 Share Posted December 24, 2012 Unofficially Agreed. The fact that there's some official definition of a white Christmas is kind of ridiculous. It's an emotional thing, and if someone is happy with a few flurries or a T on the ground, then that should be good enough. Link to comment Share on other sites More sharing options...

Huffwx Posted December 24, 2012 Share Posted December 24, 2012 NAM has cold bias-- we went from not even close to an inch of snow WAY down here. (Not the elevations to my NW) Link to comment Share on other sites More sharing options...
Solo2 Posted December 24, 2012 Share Posted December 24, 2012 I noticed Martinsburg was 42 last hour I even checked to see if it just hadn't reported, but that was a current temp It's just warm in N. MD. Manchester is warm too and Hagerstwon is mostly reporting upper 30's. It's 37.7 here now...up from 31 a few hours ago. Not a good trend.

Huffwx Posted December 24, 2012 Share Posted December 24, 2012 GFS is fine...just warmer at the surface GFS is just as cool down here-- for days I thought we had NO shot at snow tomorrow. (maybe a little onset sleet) At the very least, the kids and I could drive up to sharp top and see snow. Link to comment Share on other sites More sharing options...

That may get us wet flakes but also could be rain. Link to comment Share on other sites More sharing options...

wxmeddler Posted December 24, 2012 Share Posted December 24, 2012 IMHO, It's game over for anyone below the fall line / SE of 95.. if people in these areas (ie. AA/PG/DC) start as rain, its going to be all rain. If your NW of 95 and you start as snow, then you may have an hour (more NW) to see flakes. Fredrick, Carroll, York and Lancaster are best lined up to see 2+ hours of snow before changing over later in the evening. Still sticking with this.
