nj2va Posted January 3, 2014 Share Posted January 3, 2014 Brutal. Certainly possible if radiational cooling is present and no winds. True, won't be any snowcover left, but still possible IMO Yeah, I'm not sure I believe the city gets below 0 but possible. Euro is only a few degrees warmer than the GFS.

das Posted January 3, 2014 Share Posted January 3, 2014 Yeah, I'm not sure I believe the city gets below 0 but possible. Euro is only a few degrees warmer than the GFS. Not for you personally but for anyone: Does the Euro still have that physics problem leading to colder minT forecasts or was that fixed? Link to comment Share on other sites More sharing options...
HighStakes Posted January 3, 2014 Share Posted January 3, 2014 Not for you personally but for anyone: Does the Euro still have that physics problem leading to colder minT forecasts or was that fixed? I don't know if anything was fixed or even addressed but the Euro was pretty spot on with today's cold blast. It was way too cold for the cold fronts back in December. Next tuesday will be a big test. Link to comment Share on other sites More sharing options...
WEATHER53 Posted January 3, 2014 Share Posted January 3, 2014 i was thinking about that too -- do you happen to know how far back there are hourly obs at DCA (or other regional sites) -- be interested to look at the integrated 24-hour average temps rather than max-min for the average -- as you said, days like today don't really look that impressive in the record book Lots of opinions on this but besides all the development that has occurred in and around DC over last 100 years, transforming what used to be like Germantown into a Macadamopolis and thus complimenting global warmers(Nation's Capitol is 5-7 degrees warmer than 100 years ago!!!!) there is the inherent bias that occurs at 12:01am that does not occur at 12:01 pm. That is, we frequently have our high temeprature at 12:01 am, we almost never-never have our low temperature at 12:01pm. Link to comment Share on other sites More sharing options...

But we do have low temps at 11:59pm, which is the "opposite" of the midnight high. Link to comment Share on other sites More sharing options...
WVclimo Posted January 3, 2014 Share Posted January 3, 2014 Maybe in the metro areas the snow cover will likely be gone by Tuesday, but not a foregone conclusion here. GFS has my area above freezing for about 9 hours at night Sunday night and below the rest of the time until the next arctic front. Not sure that can wipe out what's on the ground, not to mention we could get a fresh coating with the front. Link to comment Share on other sites More sharing options...

snowfan Posted January 3, 2014 Share Posted January 3, 2014 High IMBY was 21 and now already down to 17. I'm going to be shocked if I make it all the way down to -1, which is my forecasted low, but I'm hoping it happens. Link to comment Share on other sites More sharing options...

RIC Airport Posted January 3, 2014 Share Posted January 3, 2014 Brutal. Certainly possible if radiational cooling is present and no winds. True, won't be any snowcover left, but still possible IMO As we know, DCA is already hard to hit 0°F or below to begin with. I see Dulles dropped to -3°F on January 13, 1981 with no snowcover. I did no official search for DCA, it was just a random date since I was researching the same info for Richmond and it hit 2°F there on that date with no snowcover. Edit: DCA's low on 1/13/81 was just 11°F Link to comment Share on other sites More sharing options...

Not positive but I don't think there was much snowcover in the January 1985 blast as well. You are correct. Richmond hit 3°F back then and the high was only 14°F. I only chose 1/13/81 because for Richmond, it's the closest we've gotten to 0°F with no snowever in recent times. I don't know what the snow depth status was for DCA and IAD in 12/1983, I'll leave that for Ian or snow. unless they want me to look for them.

No snowcover in the DC and Balto. area during the 12/83 cold wave. A few snow showers and squalls accompanied the front and coated the ground but not enough to be considered snowcover. I'm sure there have been many more major cold waves that had no snowcover. If Ihave time later I will look into it. Link to comment Share on other sites More sharing options...
