Some new weather records were set in the D.C. area on Tuesday.
Reagan National and Dulles International airports both saw highs at 55. At BWI Marshall Airport, the high was 55, both breaking records for lowest high for Oct. 4.
In weather terms, the lowest high temperature for a given day is known as the lowest maximum. We’ll call it LOMX, because that’s what meteorologists do. Basically LOMX is the ceiling, but not the basement for daily temperatures, (the HI in HI | LO).
The previous record for LOMX on Oct. 4 was 56 degrees, set in 1998 at Reagan National, and 2010 at Dulles Airport.
The record LOMX at BWI Marshall is 54 degrees; they got up to 55 today. No record.
Either way, it isn’t normally this chilly until later in the month and definitely unusual for highs (LOMX!) to be below 55 before late October. Temperatures early Tuesday morning were around seven degrees below average, Storm Team4 meteorologist Chad Merrill said.
