  3. October 2, 2019 is in the record books for the hottest October maximum in DC, Baltimore, and Dulles. The respective maximums today were 98, 98, and 96. The previous record for DC and Baltimore was set on October 5, 1941, with respective maximums of 96 and 97. The previous record for Dulles was set October 9, 2007, at 94.
  4. Minor correction for DCA: According to the Capital Weather Gang, September 2019 was the 3rd warmest and 4th driest September in DC history; see https://www.washingtonpost.com/weather/2019/10/01/washington-just-posted-its-rd-warmest-th-driest-september-record

  8. You're looking good right now, while I'm headed from first to worst. By the way, I think Richmond hit 99 a couple of weeks ago, but that may look cool by the time the weekend ends.

  10. Another DC precipitation record has just fallen. The previous DC record precipitation from the second half of one year to the first half of the following year was 62.16 inches, set during July 1885 to June 1886. With 0.62 inches already recorded at DCA tonight, the July 2018-June 2019 total there is 62.53 inches and counting.

  12. Most of us have complained at some point about rainy days seeming to occur more often on weekends than on weekdays. However, as the Capital Weather Gang recently noted, that has actually been the case this year in this area, assuming that the weekend is defined to include Friday; see https://www.washingtonpost.com/weather/2019/05/13/washingtons-wettest-days-history-inches-precipitation-have-fallen-past-year/?utm_term=.2bb2b4bf05c4. Specifically, through the first 19 weeks of 2019 at DCA, there have been 32 weekend days on which measurable precipitation has fallen vs. only 17 weekdays on which measurable precipitation has fallen. Moreover, because there are more weekdays than weekend days, the percentage of weekend days that have received measurable precipitation is 56% (32 of 57 days) vs. only 22% for weekdays (17 of 76 days). I just ran a two-tailed T-Test to determine the probability of this pattern occurring randomly, and it works out to be about one chance in 730. So, is this rainy weekend pattern here just a fluke, or is there more to it than that?
  13. You're right that last April was relatively cool at DCA -- 54.9 degree average, which was 1.9 degrees below the 1981-2010 normal, and 7.5 degrees cooler than this year.
  14. April 2019 averaged 62.4 degrees at DCA, second all-time in DC to the 63.8 recorded in April 2017. However, precipitation was only 2.24 inches -- the first below normal month at DCA since October 2018.
