Severe storms to deliver strong winds, flash flooding in eastern, central US
Arthur will promote severe weather conditions along part of the Gulf Coast on Thursday as batches of strong thunderstorms rumble elsewhere in the east with strong winds and heavy rain.
Following the severe weather outbreak in the Midwest on Wednesday, powerful thunderstorms are forecast to rattle parts of the East on Thursday and return to the Plains and Midwest over the weekend.
As a cold front pushes into the Northeast on Thursday, winds will be unusually strong for June, even without thunderstorms, and capable of breaking tree limbs and sending unsecured objects in the yards or for trash collection sailing through neighborhoods. Gusts of 40-50 mph will be common from Ohio and northern Kentucky to the Appalachians. Sporadic power outages are likely.
As the Midwest gets a break from severe weather, pockets of intense thunderstorms are in store for the Northeast and the Southeast with torrential downpours that can lead to flash flooding, hail and frequent lightning strikes, in addition to damaging wind gusts.
One zone will focus on New England, eastern New York, northeastern Pennsylvania and northern New Jersey while another stretches from southern Missouri and northern Arkansas to Delmarva and the New Jersey and Virginia capes.
A third batch of severe weather will focus farther south and will be associated with the inland track of Arthur on Thursday.
From southeastern Louisiana to central and southern Georgia, there is a risk of strong wind gusts, tornadoes and torrential downpours that can lead to flash flooding.
Coastal areas from eastern Louisiana to the Florida Panhandle could be at risk for waterspouts on Thursday.
A few big storms may erupt on Friday in parts of Texas and Oklahoma, as well as along the coasts of the Carolinas, Georgia and perhaps the Florida Peninsula.
A new focus of severe weather will ramp up over parts of the Plains on Saturday as a potent storm rolls out of the Rockies.
A surge of warm, humid air over the southern Plains will collide with a large wedge of cooler, drier air over the Midwest, sparking thunderstorms over the region.
The main threats on Saturday and Sunday are expected to be high winds and hail. However, at this early stage, a few tornadoes cannot be ruled out as the parent storm moves from Nebraska and Kansas on Saturday to the Ohio Valley by Sunday.
Where downpours overlap from previous days, there will be a heightened risk of flash flooding.
