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.
