Humid conditions could turn into stormy weather Friday

Friday’s humid conditions could give way to strong storms in the evening throughout the D.C. region, bringing gusty winds, heavy rain and lightning. Here’s what you need to know.

7News First Alert meteorologist Jordan Evans said after a mostly sunny day — with temperatures ranging between the upper 80s to lower 90s — a cold front heading to the region brings the potential for a few scattered showers and thunderstorms in the evening.

“Some of those storms may contain brief, gusty winds and some heavier downpours,” Evans said. “Most will be concentrated north and northeast of the District.”

The storms are expected to end by midnight with dry but less humid conditions for the weekend, Evans said. Father’s Day is set have clear conditions with temperatures ranging between 75-80 degrees.

The possible storms will give the region a break from the heat, as the heat index is set to be as high as 95 in some parts. Friday’s high temperatures probably won’t break records at regional airports on Friday — likely peaking in the low 90s.

The record high heat for June 14 at Reagan National Airport was in 1954 at 98 degrees and 94 degrees at Dulles International and BWI Airport in 1994, according to the National Weather Service.

Friday was set to potentially be the hottest day of the year so far, with the D.C. government activating the District’s first Heat Emergency plan of the year.

“During a Heat Emergency activation, residents are urged to stay cool, check on seniors and other vulnerable neighbors, and to call the shelter hotline for unsheltered residents in need of free, accessible transportation to a cooling center,” a news release said.

After the mild weekend, prepare for a big warm-up. A heat wave is expected next week with highs in the 90s nearly every day.

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.
