Falling temperatures and possible storms in DC area’s forecast

A foggy morning and passing rain showers Tuesday are a prequel to what’s expected to be an impactful weather system bringing gusty storms to the D.C. region.

The chance for rain increases after sunset on Tuesday. The wet weather will continue as heavy showers soak the region through Wednesday afternoon.

Morning commuters should prepare for a slippery drive into work with possible ponding. Along with the heavy rain, storms could bring thunder and damaging winds.

“Winds picking up as the front moves through,” 7News First Alert Meteorologist Jordan Evans said. “Some of those wind gusts, especially east of I-95, may reach severe limits up to 55 mph.”

Winds are expected to pick up Wednesday afternoon. Make sure to secure any outdoor holiday decorations or store them inside and be ready in the event the power is knocked out.



7News Chief Meteorologist Veronica Johnson also said rain totals could reach over an inch Wednesday, adding wind gusts were expected to hit 35 mph.

“Rainfall will be heavy through the afternoon with rain tapering off from west to east shortly after sunset,” Johnson said.

The most severe weather is expected to move through the region from 10 a.m. to 7 p.m., Johnson said.

After enduring all that, the reward is the return of bone-chilling temperatures Thursday. Wind chills will drop back down to as low as 19 degrees Thursday morning.

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.
