WinterWxLuvr Posted November 26, 2013 Share Posted November 26, 2013 Single digit dew points should yield some IP / -SN burst at the start. The earlier the better for everyone. You said there would be NO snow. Link to comment Share on other sites More sharing options...
wxmeddler Posted November 26, 2013 Share Posted November 26, 2013 Sleet? Nevermind. Didn't even see the best guess section on the lower right. If this profile all the sudden became saturated, it would be snow. The blue line is the wet-bulb, which is below freezing at all levels. Link to comment Share on other sites More sharing options...
yoda Posted November 26, 2013 Share Posted November 26, 2013 33/6 at IAD and 35/10 at DCA and 32/7 at BWI at 7pm... going to be interesting to see how lo we can go... perhaps a sneaky upper 20s Link to comment Share on other sites More sharing options...
Huffwx Posted November 26, 2013 Share Posted November 26, 2013 If this profile all the sudden became saturated, it would be snow. The blue line is the wet-bulb, which is below freezing at all levels. It seems like that NEVER happens and the WB rises as the temp does and we get sleep. Especially with no cold air advecting in.. Link to comment Share on other sites More sharing options...

WinterWxLuvr Posted November 26, 2013 Share Posted November 26, 2013 For out there or the WWA crowd? Just going off the crude NCEP maps, looks cooler for everyone up this way.

Eskimo Joe Posted November 26, 2013 Share Posted November 26, 2013 You said there would be NO snow. Conversational snowflakes at worst...but then again DC can't drive so it'll be chaos over a flizzard. Link to comment Share on other sites More sharing options...

DDweatherman Posted November 26, 2013 Share Posted November 26, 2013 NAM actually shows a way to get presentable (meaning a few hr period of SN possibly) backside snows, watch sfc temps though, thats your key. The ULL track is what you'd desire though. Will examine further in a few. Link to comment Share on other sites More sharing options...
