A severe outbreak with strong, long-track tornadoes likely
A severe thunderstorms outbreak with widespread damaging winds, tornadoes, and large hail is likely today and tonight from the Midwest into the Deep South. The strongest storms will have the capability to produce winds as strong as winds in a category 1 hurricane—potentially up to 80 mph, strong long-track tornadoes—EF2+, and very large hail—larger than golf balls.
The Storm Prediction Center has a large severe risk from the Great Lakes to the Gulf Coast states with many areas along the Mississippi River, from the Mid-Mississippi Valley to the Lower Mississippi Valley, under a moderate (level 4 of 5) severe risk [red].

Numerous large Metro areas are included within the risk, placing tens of millions of people in an elevated severe and tornado today and tonight.

Have a shelter plan in place and know where to get weather warnings from
If you live anywhere in or near the severe risk areas, please have a plan in place. Know where you will shelter if a warning is issued for your area. Also, have a few reliable weather sources to receive accurate, timely severe weather warnings from. It would be wise to go ahead and charge your electronic devices in case you lose power or have to seek shelter without adequate charging options.
