Forecasts for last night’s freezing temperatures in the Washington, D.C. area verified pretty well. Overnight lows ranged from the upper 20s to mid-30s.
Most spots outside of the urban core at least touched freezing. Dulles Airport (IAD) dipped to 30 and BWI 31. Within the urban heat island, Reagan National Airport (DCA) only dropped to 34.
While cold relative to the exceptionally mild weather of late, these lows were well shy of the records of 20 at DCA (1894), 17 at IAD (2001), and 20 at BWI (2001).
This morning’s coldest lows - in the upper 20s - were on the west and north side of Montgomery county and west and north of there. Gaithersburg fell to 27, Frederick 29, and Hagerstown 27.
For my part, I predicted lows of 35 at DCA (off by one), 31 at IAD (off by one) and 31 at BWI (correct).
Because - in most locations - temperatures only briefly achieved freezing levels and did not fall below 28 for at least three hours, any damage to plants is likely to be minor.
