Both Washington Dulles and BWI airport set record lows this morning, as the historic November cold blast focused on the eastern third of the Lower 48.

At Dulles this morning, the mercury plunged to 13 degrees, shattering the old record of 20 degrees set in 1990. (Records at Dulles date back to 1963.)

BWI Airport dipped to 19 degrees, besting the previous mark of 20 set in 1936. (Records in Baltimore go back to 1871 but, prior to measurements at BWI in the 1940s, were observed downtown – a warmer location.)

Reagan National Airport, the District’s official observing location, fell short of the daily record of 18, which was set in 1891 (when temperatures were measured at 24th and M St. downtown, beginning in 1871). It dropped to 22 – still the coldest reading at Reagan National so early in the season since November 14, 1986, when the mercury fell to 21 degrees.

Additional cold weather records are possible this afternoon. The record low maximum (high) temperatures of 35 at BWI (from 1880) and 38 at Dulles (from 2008), are both in jeopardy.

Even though Reagan National’s afternoon temperatures should exceed the record low maximum of 33 (from 1880), as long as temperatures hold in the 30s, it will be the coldest day so early in the season since November 14, 1996.

On Tuesday, Dulles Airport established record lows for both the maximum and minimum temperature, rising to only 36 degrees (just after midnight), with a low of 19 (just before midnight about 24 hours later).

Wednesday’s records in the D.C. and Baltimore areas join more than 180 others in the eastern U.S.

Several record lows were set in the New York City area, including both Laguardia and JFK Airports.
