Baltimore Sets Two Records on 11/11/2020

As Tropical Storm Eta moves northward along the west coast of Florida, a ton of partially associated moisture has been streaming all the way up through the Mid-Atlantic States. According to the NWS, Baltimore-Washington International Thurgood Marshall Airport received 1.91″ of rain on 11/11/2020, breaking the previous record of 1.34″ from 1987. Current radar is showing quite a bit more rain, some very heavy (numerous flood warnings are in effect), will continue falling on 11/12/2020, the record for that date being 1.82″ in 1925. Will it be two consecutive days of daily records?

A second record that was set at the Baltimore airport on 11/11/2020 is the number of consecutive days with November maximum temperatures ≥70°. Today, the Maximum of 70° marked the 8th day in a row, now surpassing the previous record of 7 days from 1975.  The 8 total days (including non-consecutive) with Temperatures ≥70° currently places 2020 in 3rd place, behind the the 9 days in 1994 and the 11 days in 1975.

UPDATE ON 11/12/2020: The Maximum Temperature of 70° today (just after midnight at 12:18 AM) marks the 9th consecutive day with a November temperature of ≥70° and now ties 1994 for 2nd place for all November days ≥70°. Additionally, the rainfall total of 2.62” covering a 24-hour period 11/11/2020 to 11/12/2020 ranks as #10 highest November amount.

  1. The very narrow zone of heavy rainfall resulted from an extremely moist air mass, converging air and a weak disturbance over the area. These ingredients indicated the potential for heavy rainfall somewhere in the region, but predictive models did not show it occurring where and when it did. The heaviest rainfall totals, exceeding four inches, focused in the area from Northeast D.C. through College Park to around Adelphi in Prince George’s County. Hyattsville received 6.35 inches, the highest amount recorded.
