Severe Weather Threat for Southeast, Mid-Atlantic and Plains Wednesday
The strong storm system moving through the Southeast will create a the chance for isolated severe storms Wednesday. The severe weather threat extends to the Mid-Atlantic as well.
A separate storm system organizing in the lee of the Rockies will bring isolated to scattered severe storms for the plains of eastern Colorado, western Kansas and the Texas and Oklahoma panhandles later this evening.
For Wednesday, the severe weather risk shifts to the Chesapeake Bay through North Carolina and from Florida’s Big Bend to southeast Georgia and South Carolina.
Strong wind gusts of 60 mph is the main concern for the marginal risk (level 1 on a scale of 1 to 5). Gusty winds and hail are also the primary threat for the Plains.
The hail risk is for parts of the Mid-Atlantic, Gulf Coast and Southeast. Hail could be up to 1″ in diameter with the strongest storms.
Gulf Coast and Southeast
Instability, or surface energy, is expected to be lower on Wednesday than earlier in the week. However, energy will still be strong enough aloft and along the cold front to create isolated severe storms especially along the Gulf Coast and Florida panhandle.
As the cold front moves slowly to the south and east Wednesday afternoon, thunderstorms will develop along and ahead of the system. Overall coverage and strength will not be as widespread as earlier this week. Scattered severe storms are possible especially in the afternoon during peak heating hours.
The front will stall along the coast, making for slow storm movement and the potential for several rounds of storms. Gusty winds and large hail remain the main threats through the afternoon and early evening, along with heavy rain and flooding.
The cold front will have a better jet stream energy and movement to the east further north, in the Mid-Atlantic.
Heavy rain and thunderstorms will develop in Pennsylvania and New Jersey through the mid-morning hours. Isolated storms along the I-95 corridor as far south as Washington DC are possible.
As the first round of rain moves from the Northeast offshore into the Atlantic Ocean, there will still be enough energy to get a few isolated storms to develop through the late morning and early afternoon east of the I-95 corridor in eastern Virginia and Maryland. These storms will mainly pose a gusty wind threat but hail larger than 1″ is also possible with these storms.
By early evening the energy will be offshore and the severe weather threat will end.
Colorado and Kansas
A separate system organizing east of the Rockies also brings the chance for a few isolated to scattered severe storms this afternoon and evening from eastern Colorado, western Kansas and the Panhandles of Oklahoma and Texas.
Gusty winds are the biggest threat with storms in these areas.
Hail larger than 1″ in diameter will also be possible.
Thunderstorms will start to form in the early afternoon east of I-25 in eastern Colorado.
While storms will be isolated through much of the afternoon, wind gusts could top 60 mph at times.
Storms will push into Kansas and Nebraska this evening. Gusty winds and heavy rain will remain the biggest threats, but reports will likely be very isolated.
Thunderstorm activity should diminish after sunset as energy levels decrease.
