Scattered thunderstorms possible in DC region for Sunday evening

While previous severe weather watches have been cancelled, we’re keeping an eye out for scattered thunderstorms and high winds as we head into Sunday evening. Here’s what we’re looking at tonight:

  • Increasing clouds throughout the day.
  • Afternoon showers and potentially thunderstorms.
  • Breezy, winds blowing 10-20 mph.
  • Warmer temperatures, highs in the upper 70s. 

On Sunday afternoon, high winds in Frederick, Md., brought about downed trees and power lines, including a power pole that was snapped in half on Hunting Rd. For most of the region, clouds will increase throughout Sunday. Thunderstorms are possible as the low pressure center swings its cold front toward the area, Storm Team 4 Meteorologist Clay Anderson reports.

Ahead of the front, temperatures will rise into to the upper 70s by the afternoon. Once the cold front sweeps through Sunday evening, winds will become westerly and bring drier air back into the D.C. area. Chances for showers and storms will diminish by midnight with a gradual clearing overnight.

CURRENT CONDITIONS

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.
