Ian Posted December 11, 2011 Share Posted December 11, 2011 Do you know the year and least number of December days DCA hit freezing? Looking at the extended models, after tonight and maybe tomorrow, it may be a long while before it happens again. here's the top (lowest) 10 for winter season 2007-2008 41 1931-1932 42 1997-1998 42 1948-1949 45 2001-2002 46 1990-1991 47 1973-1974 48 1982-1983 49 1999-2000 51 1974-1975 52 Link to comment Share on other sites More sharing options...

jonjon Posted December 11, 2011 Share Posted December 11, 2011 Geebus! Do you still have snowcover? I would have thought last night was textbook for inversions. Yes, a few inches on the ground and we are in a valley at 3100'. We're high but low if you know what I mean. Link to comment Share on other sites More sharing options...

snownut Posted December 12, 2011 Share Posted December 12, 2011 No whining here. Pleased with season IMBY. October surprise, nice squall in November, and thick stubborn little December elevation snow. I am in WV which helps with colder temps, but not Jon Jon high country or snow belt. Some snow on the ground 10 days this season and all with without any bitter cold. Web cam shot from moments ago. Link to comment Share on other sites More sharing options...
BethesdaWX Posted December 12, 2011 Share Posted December 12, 2011 Made it to 21.6 this morning, almost 7 degrees colder than Saturday morning, surprisingly. Link to comment Share on other sites More sharing options...
Ellinwood Posted December 13, 2011 Author Share Posted December 13, 2011 My boss likes our potential for snow Friday night into Saturday (16th-17th). Been following it's progression over the last couple of days... showing improvement as we go along, with a nice baroclinic zone and vort. max cutting through south of DC and high pressure pushing in cold air to the north. Teleconnections looking favorable around that time, reflecting the pattern we're starting to see evolve on the models. Link to comment Share on other sites More sharing options...

There does seem to be a chance which is a good thing given how it has been looking from the start of Dec. Side note: DCA 3 days of sub 32 low?

As Ian said, I think it's technically the 4th day because the first freeze came late on the 10th. I could be wrong though. Link to comment Share on other sites More sharing options...

I'm just a cold weather person, my asthma is better in this weather and its easier for me to run... nice plus that there is also a lot less sweating!

WxUSAF Posted December 13, 2011 Share Posted December 13, 2011 6z GFS Op and ensemble mean and 0z Euro Op and ensemble mean all show a pretty decent pattern developing with a +PNA and the PV displaced south toward Hudson Bay. Still looks like transient cold shots since upstream blocking is weak, but certainly more of them and colder air associated with them. Link to comment Share on other sites More sharing options...

Can you explain for those of us who don't know all the details of PNA what that means? TIA Link to comment Share on other sites More sharing options...
