RodneyS Posted June 8, 2016 Share Posted June 8, 2016 After failing to reach 80 degrees until May 24th, DCA has now recorded eight consecutive maximums in the 80s. When was the last time that May 24-31 each had maximums in the 80s in DC? Never since official daily temperature record-keeping began in 1872. The closest previously was in 1911, when all but May 30th had maximums in the 80s. However, that day reached an even 90. Today marked the 15th consecutive day -- May 24-June 7 -- of a maximum in the 80s at DCA. While the streak is likely over, it did, according to my records, break the all-time DC 80s streak for the first half of the year. I believe that the previous record-holder for that time frame was June 15-28, 1907 (14 days). The all-time record for consecutive days with a maximum in the 80s, I believe, is August 11-September 1, 2001 (22 days). Link to comment Share on other sites More sharing options...

RodneyS Posted July 5, 2016 Share Posted July 5, 2016 DCA July 4th maximum of 74 was the lowest since DC's all-time low maximum of 68 on July 4, 1941. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted July 26, 2016 Share Posted July 26, 2016 Today was the first 100+ day for BWI since July 18, 2012. Today also tied the record high of 100 set in 2010. Link to comment Share on other sites More sharing options...

First 100+ at DCA since July 26, 2012, and first at IAD since July 18, 2012. DCA tied the record for July 25th set in 1930 and IAD broke the record of 98 set in 2010.

Ian Posted July 28, 2016 Share Posted July 28, 2016 DCA hit 97+ five days in a row... should be it. Ties for the 4th longest stretch of 97+ in DC. Link to comment Share on other sites More sharing options...

And today marked the 13th consecutive day of at least 90 degrees at DCA, with forecasts tomorrow calling for a high in the mid-80s. Last year we also "officially" had 13 consecutive 90+ readings (during July 24th-August 5th), but that was right before the DCA temperature sensor was replaced on August 10th, with a reference sensor (psychro-dyne) showing a reading of 1.7 degrees too high on the old sensor. Prior to that, DCA had 16 straight 90+ readings July 18-August 2, 2011. The all-time record is 21 straight 90+ readings July 25-August 14, 1980. .

wxdude64 Posted August 4, 2016 Share Posted August 4, 2016 Blacksburg VA did something yesterday I haven't seen in a while. They tied both their record warmest low and coolest high on same day with a 68 and 71 reading. Big 3 degrees difference, which is also hard to pull off this time of year. They also set a rainfall record for the day with 0.95 inches. Link to comment Share on other sites More sharing options...

wxdude64 Posted August 9, 2016 Share Posted August 9, 2016 I broke my record low max with a 69.1 reading for the day, beating old mark of 70 from 1995. Link to comment Share on other sites More sharing options...
RodneyS Posted August 16, 2016 Share Posted August 16, 2016 Yesterday marked the third consecutive 100 degree or higher reading at DCA. The only other time that happened in August in DC was the legendary summer of 1930, which saw August 3-5 do it. If we hit 100 or more today at DCA, that will tie both 1930 (July 19-22) and 2012 (July 5-8) for having the most consecutive days that reached at least 100.

Ian Posted August 16, 2016 Share Posted August 16, 2016 Think we got too much rain last night. Temp of 82 at 10 would require a pretty huge rise to get to 100. We might get some upper 70s dews tho later. Link to comment Share on other sites More sharing options...

PrinceFrederickWx Posted August 17, 2016 Share Posted August 17, 2016 I think BWI has a good shot at a top ten hottest August. If the airport were to maintain its current +4.5 departure that would be a 6th place finish. Link to comment Share on other sites More sharing options...
Ian Posted September 1, 2016 Share Posted September 1, 2016 Summer 10-12 is back. :< For DC... Most 90 degree days on record in August 2nd hottest August (by one degree on one day of the month) Hottest July/August 3rd hottest summer Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted September 1, 2016 Share Posted September 1, 2016 Tied for 6th hottest August at BWI: however, summer was only tied for 15th hottest. Also three of the last nine months at BWI (December, March and August) have been tied for 6th or higher for heat. Link to comment Share on other sites More sharing options...
MN Transplant Posted September 1, 2016 Author Share Posted September 1, 2016 IAD with the hottest August on record by a decent margin. 3rd hottest summer behind 2010 and 2011. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted September 9, 2016 Share Posted September 9, 2016 BWI has a good chance of breaking the record high of 94 that was tied... last year. What is it with Sept. 9 now? I think Sept. might have a good shot at top ten hottest too, but its too early to tell. Link to comment Share on other sites More sharing options...

PrinceFrederickWx Posted September 13, 2016 Share Posted September 13, 2016 I'm thinking more and more that BWI can pull off a top ten hottest- as of yesterday they were +5.7. If we finished with that departure it would be 7th hottest. Today and tomorrow are going to push that departure even higher. Thurs and Fri look near normal and the weekend and beyond look above average. Of course it could fall apart at the end of the month but its looking good to me now. If it happens, this would be the first back-to-back top ten hottest months since June-July 2010. Link to comment Share on other sites More sharing options...

You're welcome, and as you have noted, the DCA record of 81.7 for the 1980 astronomical summer is suspect, as it exceeded the IAD temperature of 76.1 by 5.6 degrees. So, a faulty DCA sensor may have been a significant factor in that record. Link to comment Share on other sites More sharing options...

I just discovered that the September 2016 DCA average minimum of 68.6 broke the all-time DC record of 68.2 set in 1881. On the other hand, the September 2016 DCA average maximum of 83.4 didn't even approach the 1881 record of 88.2. In fact, this year's September average maximum was slightly below last year's (83.5) and ranks only 13th all-time. Link to comment Share on other sites More sharing options...

PrinceFrederickWx Posted December 14, 2016 Share Posted December 14, 2016 There are only two times in history that BWI has gotten back-to-back shutouts (T or 0) in December: 1888-1889, and 1971-1972. Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted December 15, 2016 Share Posted December 15, 2016 Also, there has never been a back-to-back combined Nov/Dec shutout ever- in both those periods above, there was snow in November but not December for one of the years (Nov 1888 and Nov 1972).
