PM Update: Record-breaking warmth likely again on Monday.

Record highs in the upper 70s were set at Dulles and BWI Marshall airports Sunday.

An afternoon surge of warm air led to some record-breaking temperatures across the region this afternoon. Dulles and BWI airports both hit 78 degrees, breaking records of 70 degrees (from 2004) and 76 degrees (from 1935). Reagan National, which also hit 78, feel just shy of its record of 81 degrees from 1961. More records are likely to fall on Monday, as we are likely to see temperatures hit the 80-degree mark before a sharp drop off after a cold frontal passage later on Monday.
