RodneyS Posted January 6 Share Posted January 6 22 hours ago, RodneyS said: The 60+ degree weather streak at DCA to begin the New Year has reached a DC record five days. However, that streak will almost certainly end today, and so will not challenge the more general eight-day January 60+ degree streak that began on January 2, 1998. The 60+ degree weather streak has ended, but it established a DC record for the first five days of the year for both average maximum and average mean temperatures. January 1-5, 2023 averaged a 65.0 maximum, breaking the January 1-5, 2000 record of 62.3; and a 55.6 mean, breaking the January 1-5, 1950 record of 54.5.

RodneyS Posted February 1 Share Posted February 1 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. 1 Link to comment Share on other sites More sharing options...

That was the 4th 80-degree plus February reading in DC history, with the highest being 84 on February 25, 1930. IAD also broke the record today with a maximum of 80 (old record 77, set in 2017). That tied February 21, 2018 for the highest February reading in IAD history. 1 Link to comment Share on other sites More sharing options...

Its a Breeze Posted February 24 Share Posted February 24 Not close to Christmas Eve Eve's 43 degree same day temperature change, but yesterday's 36 degree temp change (in the wrong, but felt so right, way) was the second 35+ degree same day change we've seen so far this season...

Once the mesonet stations go in this year, we'll have better access to identifying mesoscale features and supporting warn-on (hopefully!) processes. Really exciting times coming locally to summer weather lovers. 1 Link to comment Share on other sites More sharing options...

January 1950 is # 1 at 48.0 and January 1932 is # 2 at 46.8. February 2023 was another warm one at DCA, averaging 46.8 degrees, good enough for third all-time in DC, behind only 2017 (47.7) and 1976 (46.9). Moreover, while neither January nor February 2023 broke the DC average monthly high temperature record, the two months combined did, averaging 45.9 degrees for the first 59 days of the year. The previous record-holder was January-February 1932, which averaged a full degree lower, at 44.9 for the first 60 days (60 days because 1932 was a leap year. However, if the first 59 days of 1932 are used instead, they also averaged 44.9.) 1 3 Link to comment Share on other sites More sharing options...

The 2022-23 meteorological winter (DJF) at DCA was the third warmest in DC history, averaging 43.9 degrees on a true (90 day average) basis. Interestingly, two long-ago winters have it beat -- 1931-32 (91 days) averaged 44.7 and 1889-90 (90 days) averaged 44.3. 2 Link to comment Share on other sites More sharing options...
PrinceFrederickWx Posted March 1 Share Posted March 1 I'm calculating the unweighted DJF average for BWI to be 42.0, which is tied for 4th warmest with 1880 and 1950. 1 Link to comment Share on other sites More sharing options...

Late 1940's / early 1950's seemed to be an incredibly warm and bad stretch too: The 1948-49 winter was 3rd warmest, and 1949-50 was tied for 4th warmest. 1949-50 was also the least snowiest year on record for BWI. Somehow 1948-49 managed to score 19.9" despite being so warm though. 1950 did feature a colder than average March after the DJF torch though. 1 Link to comment Share on other sites More sharing options...

dallen7908 Posted Friday at 12:14 PM Share Posted Friday at 12:14 PM Yet another excuse if 2023-2024 fails to deliver. "When Hunga Tonga–Hunga Ha‘apai (HTHH) erupted in January 2022, it shot the standard volcanic cocktail of ash, gas, and pulverized rock into the sky. But the eruption included one extra ingredient that’s now causing climate concerns: a significant splash of ocean water. The underwater caldera shot 146 metric megatons of water into the stratosphere like a geyser, potentially contributing to atmospheric warming over the next 5 years, according to a new study published in Nature Climate Change. The model calculated the monthly change in Earth’s energy balance caused by the eruption and showed that water vapor could increase the average global temperature by up to 0.035°C over the next 5 years. That’s a large anomaly for a single event, but it’s not outside the usual level of noise in the climate system, Jenkins said." Link to comment Share on other sites More sharing options...
WxUSAF Posted Friday at 12:16 PM Share Posted Friday at 12:16 PM More than the direct warming from Hunga-Tonga, the water vapor getting into the winter stratospheric polar vortex will on balance tend to strengthen it. We already saw that in the southern hemisphere last year, with record cold winter vortex temps. Link to comment Share on other sites More sharing options...
