Thunderous Tuesday possible, but is it unusual for DC?

Mother Nature is rolling out the red carpet to spring weather in the D.C. area this week, with thunder, wind and record heat in the cards. Though some may feel as though it’s too soon for afternoon rumbles and milder temperatures, the spring-like conditions aren’t unheard of for late February in the D.C. region.



Heat

Record winter warmth happens occasionally in D.C., so that’s not out of the ordinary. Take Thursday’s forecast high in the upper 70s to low 80s. The previous record we are challenging on Thursday occurred just last year when Reagan National Airport climbed to 77 degrees.

Thunder

What about thunder rumbles in February? A front heading for the Mid-Atlantic Coast Tuesday afternoon promises to trigger a thunderstorm or two from D.C. north into Pennsylvania. One or two storms from Philadelphia to New York City could actually generate gusty winds. The National Weather Service in Sterling, Virginia, issued a wind advisory for much of the D.C. area until 7 p.m. Tuesday, warning of sustained winds from the west of 20-35 mph with gusts up to 50 mph.

Turns out, February thunderstorms have happened in the past in D.C. Digging back through observations at Reagan National Airport since the early 1970s, thunder has been noted in late February (specifically, during the year’s eighth week) in eight previous years. Those years include 1990, 1998, 2000, 2003, 2007, 2012, 2016 and 2017.

Snowfall in those winters was quite variable, so thunder in February can’t be connected to a snowless winter in D.C. Historically, thunderstorms are most common between 4 and 8 p.m. from mid-June to mid-July. Stay tuned to WTOP for the latest on the changeable weather with forecast on the 8’s.

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.
