Severe storms expected to rip DC region on another hot and humid day – WTOP

Here comes Round 2. Severe storms are expected to slam the D.C. area Wednesday during yet another hot and humid afternoon that could see the temperature spike to 94.

And the storms might produce 60 mph wind gusts along with hail and periods of blinding rain.

After a gorgeous morning in the District, the weather is expected to take a serious downturn, sparking an NBC Washington StormTeam4 Weather Alert Day.

So what, exactly, is the region looking at?



“Today will have the higher risk of severe storms in the afternoon even though Thursday has the higher overall chances for getting rain,” StormTeam4 Meteorologist Chuck Bell said.

“The reason for that is because today will be have more sunshine to start out and will therefore be the hotter afternoon.”

Storms are expected to develops after 3 p.m. Washington is at the southern edge of what the National Weather Service is highlighting as an “enhanced risk” area.

Bell said the most likely time for the severe weather is from 3 p.m. and 10 p.m.

The National Weather Service warns that the “enhanced risk” area — which includes all of the District as well as huge swaths of Maryland, Virginia, West Virginia, Delaware, Pennsylvania and New Jersey — could see large hail, damaging winds, isolated tornadoes and heavy rain.

Temperatures are projected to hit 94, but at least Thursday will be a little cooler, with highs closer to 90.

The record temperature for this date is 97 in 1941.

Severe storms have been raking much of the U.S.

Monday marked the record-tying 11th straight day with at least eight tornadoes in the U.S., said Patrick Marsh, a Storm Prediction Center meteorologist. The last such stretch was in 1980. The weather service website showed at least 27 reports of tornadoes on Tuesday, most in Kansas and Missouri but also in Pennsylvania and Illinois.

Outbreaks of 50 or more tornadoes are not uncommon, having happened 63 times in U.S. history, with three instances of more than 100 twisters, Marsh said. But Monday’s swarm was unusual because it happened over a particularly wide geographic area and came amid an especially active stretch, he said.

As for why it’s happening, Marsh said high pressure over the Southeast and an unusually cold trough over the Rockies are forcing warm, moist air into the central U.S., triggering repeated severe thunderstorms and tornadoes. And neither system is showing signs of moving, he said.

Scientists say climate change is responsible for more intense and more frequent extreme weather such as storms, droughts, floods and fires, but without extensive study they cannot directly link a single weather event to the changing climate.
