Dreary, chilly conditions continue Sunday ahead of Memorial Day warmup

Unseasonably cool temperatures and overcast conditions are in Sunday’s forecast across the D.C. region, prolonging an unfortunate trend of dreary Memorial Day weekend weather. The National Weather Service said Sunday morning that if predictions for today hold true, record low daytime temperatures could be set at each of the region’s three major airports. Sunday’s high at Reagan National Airport hit 57 degrees, tying the previous record low daytime high of 57, set in 1915. At Dulles International Airport, today’s forecast high is 55 degrees, which would be seven degrees under the lowest high temperature recorded there, in 1971. The National Weather Service forecast a record low high temperature of 55 degrees at BWI Airport. While showers and clouds are possible through the afternoon, according to NBC Washington meteorologist Lauryn Ricketts, any lingering showers will clear by the evening hours and clouds will part overnight, lending to sunnier skies on Memorial Day itself. Temperatures will rise to the mid-70s on Monday, with light winds.

Hot, humid week ahead for DC area with severe storm risk

A dangerous heat wave will grip the D.C. area through Thursday, with highs in the mid to upper 90s and heat index values between 100 and 105. Hot and humid conditions are expected through Thursday, according to the National Weather Service, which said to expect daily thunderstorm chances and a risk of severe thunderstorms. 7News Meteorologist Eileen Whelan told WTOP that most of Tuesday will stay dry, but a few late-day thunderstorms are possible, especially north and east of D.C. as storms drift south from Pennsylvania. Any storm could produce damaging wind gusts and hail, but Whelan reiterated "storm chances are low" on Tuesday. Due to a lack of air conditioning, Parkdale High School in Riverdale, Maryland, closed early at 10:30 a.m. on Tuesday, Prince George's County Public Schools said in a social media post.
