Severe Threat for South This Week

A multi-day severe weather threat could lead to strong winds, large hail and tornadoes across parts of the South and Southeast to start the work week.

A potent area of low pressure moving through the Upper Midwest and Great Lakes region will have a trailing cold front, setting the stage for severe weather across the much of the Mississippi and Ohio River valleys Monday through Wednesday.

First, on Monday, severe storms with large, damaging hail, strong winds and a few tornadoes look set to impact the ArkLaTex and the Ozarks. Warm, humid air out of the Gulf of Mexico will clash with a cold front, setting off storms that could last into the overnight hours into parts of the Ohio River Valley, although the storms should slowly weaken once the sun goes down.

Then on Tuesday, the severe threat expands and budges further east under the strengthening low. Wind will be the primary hazard with these storms, but isolated tornadoes and large hail could also accompany the strongest cells.

Strong to severe storms could rumble through areas unusually far north for this time of year. Places like Indianapolis, Indiana and Columbus, Ohio, for example, are under a slight risk for severe storms for Tuesday. The northeast ‘cutting’ motion of the strong low, meaning it’s moving through the heart of the country rather than out to sea, means it will draw up warm, unstable air out of the Gulf of Mexico and transport it far north and east.

By Wednesday, the storms concentrate across Georgia, Alabama and the Carolinas before the system moves out to sea. Again on Wednesday, strong winds appear to be the primary hazard.

Make sure you are prepared with the WeatherNation app, a NOAA weather radio and a sure way to get timely warnings in the event of a severe or tornadic thunderstorm.
