RodneyS Posted January 1 Share Posted January 1 On 11/30/2024 at 6:49 PM, RodneyS said: November 2024 at DCA has for sure broken the record high average November DC temperature of 54.8 degrees, which was set in 2001. DCA finished at 55.2, which resulted in a record high January-November average of 63.6, beating the previous 11-month record of 63.1, which was set in 2012. That puts DCA on course to break the previous DC calendar year record of 61.6, also set in 2012. All that is needed is for DCA to average 39.0 degrees or higher in December -- 39.0 would be 2.7 degrees below the 1991-2020 normal. Note: Edited on December 1st because the final November 2024 DCA temperature average was 55.2, rather than 55.1 December 2024 at DCA averaged 41.9 degrees, 0.2 above the 1991-2020 normal and tied for the 32nd warmest December in DC history. The bigger news is that calendar year 2024 at DCA averaged 61.8 degrees, which broke the previous DC calendar year record high average of 61.6, which was set in 2012. 2 2 Link to comment Share on other sites More sharing options...

I didn’t think we’d take down 2012. November really pushed 2024 over the top. Link to comment Share on other sites More sharing options...

RodneyS Posted January 31 Share Posted January 31 On 2/1/2023 at 10:26 AM, RodneyS said: DCA finished January 2023 with the third warmest (of 153 years) January average temperature in DC -- 45.2 degrees. January 1950 is # 1 at 48.0 and January 1932 is # 2 at 46.8. Quite a contrast to two years ago at DCA, even if January did finish on the warm side this year. This year's January average temperature was only 34.2 degrees -- 11 degrees below January 2023. That put DCA not only 3.3 degrees below the 1991-2020 January normal of 37.5, but also 1.2 degrees below the 1871-2025 historical DC average of 35.4. January 2025 tied for only the 92nd warmest January in DC history and was the coldest January at DCA since 32.2 in 2014. 3 2 Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted Tuesday at 02:18 PM Share Posted Tuesday at 02:18 PM How often does it occur where DCA's seasonal snow total exceeds BWI? Link to comment Share on other sites More sharing options...
RodneyS Posted Tuesday at 08:44 PM Share Posted Tuesday at 08:44 PM 6 hours ago, PrinceFrederickWx said: How often does it occur where DCA's seasonal snow total exceeds BWI? DCA became the official DC weather location in July 1945, and BWI began operations in June 1950. Thus, winter season comparisons between the two airports begin in 1950-51, and so there are now 74 winter season comparisons in the books. During those 74 seasons, DCA has averaged 15.5 inches of snow, and BWI has averaged 19.8 inches, with BWI snow exceeding DCA snow 58 times, DCA snow exceeding BWI snow 14 times, and two seasons ending in a tie. 2 1 Link to comment Share on other sites More sharing options...

RodneyS Posted Wednesday at 12:21 AM Share Posted Wednesday at 12:21 AM 2 hours ago, PrinceFrederickWx said: Wow, I’m surprised it happened 14 times! Yes, and this season may make it 15 times. By the way, the largest amount by which DCA snow exceeded BWI snow was 5.5 inches in 1979-80 -- 20.1 inches at DCA, 14.6 at BWI. On the other hand, the largest amount by which BWI snow exceeded DCA snow was 20.9 inches in 2009-10 -- 77.0 inches at BWI and 56.1 inches at DCA. Both totals were record-breakers for any year in Baltimore and DC dating back to the 1880s, and the BWI total even exceeded IAD's record-breaking total of 73.2 inches that memorable snow season 15 years ago. 1 Link to comment Share on other sites More sharing options...
