The calendar will still say "March," but the D.C. area will experience high temperatures more in line with April and May this coming week.
The latest forecast from Storm4 meteorologist Chuck Bell calls for a high-pressure system to move off the East Coast Sunday afternoon, with warm, moist air rushing in to take its place.
"It's going to be Memorial Day weekend-type temperatures," says Bell.
Temperatures are expected to hover in the middle and upper-70s Tuesday through Friday afternoon. By comparison, 78 degrees is the average Memorial Day Weekend high for the D.C. area.
The record run of high temperatures in mid-March will likely remain March 12-15, 1990, when the area saw high temperatures of 89, 87, 86, and 81 degrees over four consecutive days.
The warm weather will also mean an increased chance of thunderstorms, with the greatest risk coming on Tuesday afternoon. In addition, the warmer weather will likely bring an increase in the area's pollen counts, so residents with allergies should plan accordingly.
