PrinceFrederickWx Posted December 21, 2015 Share Posted December 21, 2015 My new goal is to tie or beat the monthly record high (77 degrees) on Christmas Eve. LWX forecast is up to 73 now. Link to comment Share on other sites More sharing options...
MN Transplant Posted December 21, 2015 Author Share Posted December 21, 2015 The highest minimum for any day in Dec at DCA is 59° on 12/5/1973. That record is in big trouble. Link to comment Share on other sites More sharing options...
Ian Posted December 21, 2015 Share Posted December 21, 2015 The highest minimum for any day in Dec at DCA is 59° on 12/5/1973. That record is in big trouble. Was about to say NWS forecast is 63 now Christmas Eve morning. GFS/Euro suggest it's above that thru midnight. Even possible we get it two days in a row if Euro is right.

Doesn't go out past 7pm, but this is a straight up obliteration from the NAM. Link to comment Share on other sites More sharing options...
Ian Posted December 21, 2015 Share Posted December 21, 2015 Also on track to finish in top 10 warmest years at DC.. tho not sure how we handle the sensor question on that one. Link to comment Share on other sites More sharing options...

Probably about the same way we handle the fact that some of the old observations were taken multiple stories up in a building in a completely different part of town. Ignore it.

Ian Posted December 21, 2015 Share Posted December 21, 2015 Today's 12z plug in for DC: Euro: 51.9 GFS: 51.0 +11 to +12 month? lol. Link to comment Share on other sites More sharing options...

I think I have Jan 1950 as the most anomalously positive month on record at DCA. +12.0 from the current norms. This could be a solid #2. Link to comment Share on other sites More sharing options...

PrinceFrederickWx Posted December 21, 2015 Share Posted December 21, 2015 What's the most anomalous single day departure on record for the airports? We're looking at a +30 or so for xmas eve? For BWI, using the 1981-2010 normals, I think 1/26/1950 might hold the record for biggest positive departure- I calculated a +37 departure for that day. 12/22/2013 was a +32 departure and the next best one I know of. For negative departure, I got -37 for 2/10/1899 and -33 for 1/19/1994. There may be others but that's the best I'm aware of. Link to comment Share on other sites More sharing options...
MN Transplant Posted December 21, 2015 Author Share Posted December 21, 2015 Super quick look at the records finds 75/60 on Jan 13, 1932 (+32 vs current norms, would be higher against the old numbers). Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted December 21, 2015 Share Posted December 21, 2015 Something else I was wondering but don't have enough data- what's the record for most number of 70+ degree days in December (and also any winter month) for BWI? Link to comment Share on other sites More sharing options...

RodneyS Posted December 22, 2015 Share Posted December 22, 2015 Super quick look at the records finds 75/60 on Jan 13, 1932 (+32 vs current norms, would be higher against the old numbers). I think you are correct for the average temperature in DC. Looking only at the maximum, I believe that January 26, 1950 has it, with a high of 79 -- 35.2 degrees above the current normal high of 43.8 for January 26th.

PrinceFrederickWx Posted December 22, 2015 Share Posted December 22, 2015 So looking at everything I think the following records are in play at BWI (hard to keep all these straight lol): Daily record high: Dec. 23, 24, 25 Daily record high minimum: Dec. 24, 25 Monthly record high: Dec. 24 Link to comment Share on other sites More sharing options...

dallen7908 Posted December 24, 2015 Share Posted December 24, 2015 Which is more likely, another December like this one or another February like last one? My hunch is that February 2015's weather was less abnormal but haven't run the statistics. Thoughts? Link to comment Share on other sites More sharing options...

My hunch is that February 2015's weather was less abnormal but haven't run the statistics. Thoughts?Just my opinion, but if we wind up with a +11 or +12 departure or something like that, I'd say this month is the more anomalous one and least likely to happen again. Shameless plug- I have a lot of the February 2015 BWI stats in the link in my signature btw Link to comment Share on other sites More sharing options...

RodneyS Posted December 25, 2015 Share Posted December 25, 2015 64 at DCA currently. Looking good to break the all time December min record tomorrow. Even with the temperature falling to 60 yesterday, DCA still established an-all time December record high minimum for DC, but fell short of the all-time meteorological winter high minimum of 61 established on February 16, 1891. IAD, on the other hand, with a December 24, 2015 minimum of 63 broke the all-time record meteorological winter high minimum of 62 established there on January 8, 1998.

PrinceFrederickWx Posted December 25, 2015 Share Posted December 25, 2015 I love how BWI fell to 61 right before midnight just to screw us out of the monthly high minimum by one degree. Then we missed the record high by one degree today too lol We got daily record high and high minimum for yesterday, and will get high minimum for today too. Next up is breaking the record high on Sunday and then breaking the record for number of 70+ highs in December. I think we've pretty much clinched hottest December ever now. Merry Christmas to all of you! Link to comment Share on other sites More sharing options...
