Dangerous heat, severe storm risk in DC region as some schools cancel outdoor activities

The D.C. region is getting hit with a one-two punch Thursday: Dangerous heat and the chance for severe storms later in the day.

In a word, Thursday is going to be gross.

Thursday is expected to be one of the hottest days so far this year, with highs climbing into the low to mid-90s. The heat index 鈥 what it feels like when humidity is factored in 鈥 could reach 100 to 105 degrees during the afternoon.

“A swampy feel with morning temperatures in the 70s, afternoon highs 95 or higher,” 791欧美激情 First Alert Meteorologist Eileen Whelan said.

The National Weather Service has issued a heat advisory until 8 p.m. for D.C., Arlington and counties east of Interstate 95.

Dulles International Airport could come close to its daily record high of 95 degrees, while Reagan National is expected to stay below its record of 101.

While much of the day may stay dry, the atmosphere will become increasingly unstable by the afternoon. Scattered thunderstorms are expected to develop between about 2 p.m. and 10 p.m.

Those storms “could be strong to severe, with damaging wind gusts, hail, downpours and frequent thunder and lightning,” according to Whelan. The Storm Prediction Center has placed the D.C. region under a level 2, 鈥渟light risk鈥 for severe weather.

All outdoor activities scheduled between 11 a.m. and 8 p.m. are canceled at Fairfax County Public Schools Thursday, including recess and after school activities.

Montgomery County Public Schools announced that Wootton High School closed at noon Thursday as the school has no air conditioning because of a burst pipe.

Anyone outside Thursday afternoon should keep an eye on the sky, stay hydrated and find air conditioning when possible.

Thursday night will stay warm and muggy, with lows in the 70s. A few spots could see patchy fog, but otherwise conditions should quiet down overnight.

Friday won’t bring any relief. It’ll still be dangerously hot and thunderstorms are expected.
