  1. BWI: 13.9 DCA: 8.1 IAD: 15.7 RIC: 4.7 Tiebreaker SBY: 4.6

  3. For October 2017 as a whole, DCA averaged 64.9 degrees, good enough for the third warmest October all-time in DC, with October 2007 the warmest at 67.0 degrees and October 1984 the second warmest at 65.2 degrees. At IAD, the average was 63.1 degrees, good enough for the second warmest October there, surpassed only by 2007 at 63.6 degrees.

  5. October 9, 2017 didn't quite equal the previous day in this area, but nonetheless established new record high minimums in both DC and at IAD for this late in the year. At DCA, the minimum was 74 and at IAD was 69.
  6. The DCA minimum yesterday (October 8th) was 75 -- by far the latest in the year that DC has had a minimum temperature that warm. The previous record-holder for a 75-degree or higher DC minimum late in the year was September 24th, when 75 was the minimum in 1970. So, this year's was two weeks later than that. Similarly, at IAD, yesterday's 73-degree minimum eclipsed the record for a 73-degree or higher minimum there this late in the year. The previous record-holder for a 73-degree or higher minimum there was September 9th, when 74 was the minimum last year. So, this year's was 29 days later, although last year's still holds the record for a late 74-degree or higher minimum there.

  8. The 2017 astronomical summer here was considerably cooler, despite the warm finish. IAD averaged 73.5 degrees, down 4.5; and DCA averaged 77.6 degrees, down 3.5. The IAD composite summer averaged 73.4 degrees, down 3.7; and DCA averaged 77.43 degrees, down 2.74.

  10. Right, although yesterday there were much higher rain totals not far from DCA. Still, I find it interesting that since I began this thread six and a half years ago, the same general pattern that existed for these two days prior to August 2011 has continued, albeit to a lesser extent; i.e., August 12th continues to be rainier than August 15th. Specifically, in the last seven years DCA has recorded 2.12 inches of precipitation on the 12th, but only 1.33 inches on the 15th. A very long-term coincidence, or something more?
  11. This year featured rain on each day, with DCA recording 0.52 inches on August 12th and 0.17 inches on August 15th. So the updated totals, 1871-2017, are: August 12: 43.07 inches total; 21 days with a trace, 53 days with measurable, 12 days with at least an inch, 5 days with 2+ inches. August 15: 12.45 inches total; 16 days with a trace, 47 days with measurable, 5 days with at least an inch, no days with 2+ inches.
  12. July 2017 at DCA finished with an average temperature of 81.7 degrees -- 12th warmest July of all-time in DC, but cooler than four of the previous seven. DCA also recorded 9.15 inches of precipitation in July -- 7th most ever in DC for that month, and the most July precipitation since the 9.44 inches in 1969.

  14. AccuWeather came up a little short, as July rainfall at DCA has totaled 9.15 inches . . .
  15. I believe that DCA's precipitation total yesterday (3.31 inches) was the 6th highest daily July amount in DC history (record is 4.69 inches on July 9, 1970), and is also the most daily precipitation at DCA since Sandy (3.85 inches on October 29, 2012, which by the way fell 0.13 inches short of the October DC record set on October 4, 1877).
