Another Monday in the 80s, another record targeted
With a warm front moving north overnight, and warmer, wetter air pushing into the region from the south, forecasters say we can expect "another very warm Monday."
The forecast high is 82 degrees for BWI-Marshall Airport. That's just 3 degrees below the record high for the date - 85 degrees, set in 1887. Dulles Airport in Northern Virginia is looking for a high of 84 degrees, which could threaten the record of 87 set for the date there in 1977.
Last Monday's forecast called for a high of 78 degrees. But the NWS folks out at Sterling, Va. regularly underestimate the warm-weather highs at BWI. So we guessed we would top that and threaten the record of 83 degrees for an April 4 in Baltimore. We did. The day's high at BWI was a record-breaking 86 degrees. It was 87 downtown for the Orioles' home opener.
So we may well threaten the April 11 record of 85.
The setup is the same. Forecasters say the wedge of cold air that has kept us cool all weekend will be moving north overnight as a warm front. Southwesterly winds and increasing moisture will mean temperatures may turn and head higher well before dawn. That will raise dewpoints, bringing us some morning fog. Once that burns off and skies clear, the April sunshine will heat us up even more.
And, just like last week, there is a cold front expected to cross Central Maryland Monday evening behind the warm front. That will raise the risk of showers and thunderstorms, probably after midnight Monday night, with as much as a half-inch of rain. There's "slight" risk some of those storms will be severe in northeastern Maryland, capable of damaging gusts and large hail.
The same scenario last week brought a small tornado to northern Charles County and brief, but powerful wind gusts to parts of Southern Maryland.
Behind the front, forecasters say we can expect more seasonable temperatures again, with highs in the 60s and lows in the 40s for the balance of the week. Mid-week looks sunny, with rain chances returning Friday night into Saturday.
