4:30 p.m. update: The preliminary high temperature reports are in and it doesn’t appear records were set. Reagan National (DCA) hit 71, three off its record, Dulles Airport (IAD) 70, one off its record, and Baltimore-Washington International (BWI) 69, four off its record.
From 1:00 p.m. (updated hourly through 4 p.m.): After Dulles airport’s record high of 70 degrees yesterday, temperatures are surging once again today, and may again reach record levels at one or more of the area airports. It’s hard to believe snow is expected in Alabama and Mississippi!
Here are today’s records:
DCA: 74, 1973
IAD: 71, 1998
BWI: 73, 1990
Here are the hourly readings from the local airports:
4 p.m.: 66 DCA, 68 IAD, 66 BWI
3 p.m.: 68 DCA, 70 IAD, 69 BWI
2 p.m.: 69 DCA, 70 IAD, 67 BWI
1 p.m.: 68 DCA, 68 IAD, 67 BWI
At DCA, today marks the 9th straight day with high temperatures above average and at least 60 degrees.
With another rare, late-season 70-degree reading seeming likely, it begs the question, how unusual are such days from now to the end of the calendar year? The National Weather Service has the answer:
IN THE WASHINGTON AREA RECORD FROM NOV 28 TO DEC 31 DATING BACK TO 1872 ONLY 70 DAYS HAVE REACHED 70F. THAT IS A 140 YEAR RECORD...SO ONLY ONCE EVERY OTHER YEAR DO WE HIT 70F AFTER NOV 27 IN THE WASHINGTON AREA.
As warm as it’s been the last 9 days, we’re averaging “just” 2.1 degrees above normal for the month at DCA, compared to 4.7 degrees above normal during the record warm year of 2001.
