Over 70 million Americans on alert for severe weather, tornadoes

Destructive, long-track tornadoes are possible from Arkansas to Ohio on Friday as over 70 million Americans prepare for potential severe weather.

Strong tornadoes, destructive winds in excess of 75 mph and very large hail the size of baseballs are possible.

More than 400,000 customers are without power on Friday afternoon, including over 200,000 in Michigan and 100,000 in Missouri, with severe weather moving through the Midwest.  

Severe storms blew through St. Louis on Friday afternoon and dumped large hail on Missouri’s St. Charles County.

One or two tornadoes may become a high-end, long-track twister. 

There is a moderate risk — level 4 of 5 — for significantly severe storms Friday, from southeast Missouri through southern Illinois, western and central Kentucky and southern Indiana. After storms move through in the morning, the majority of the afternoon will be dry and sunshine is expected. However, this will work to re-energize the atmosphere, especially considering the extremely warm air mass creating record high temperatures for surrounding areas.

Around 3 to 4 p.m. Central time, storms will begin popping up over eastern Missouri and central Illinois, which may turn severe quickly.

There will be storms over Paducah, Kentucky, and Little Rock, Arkansas, around 6 p.m. CT.

The storms will reach Indianapolis around 7 p.m.

The storms will then hit Cincinnati; Louisville, Kentucky; and Jonesboro, Arkansas, at 8 p.m. CT before hitting Memphis, Tennessee, at 9 p.m. They will reach Nashville, Tennessee, from 10 to 11 p.m.

Strong storms are possible in the Mid-Atlantic on Friday afternoon as the energy from the morning system reach the area. Strong winds and some hail are the main risks for the East Coast.

Saturday’s risk area is mainly centered over Texas, Oklahoma and Arkansas, where damaging wind, large hail and a few tornadoes are possible. These storms are expected in the evening and overnight hours.
