The National Weather Service on Friday warned that potentially strong tornadoes may develop on Saturday over the lower to middle Mississippi and Tennessee valleys. Lightning, wind gusts of at least 74 mph and hail of at least two inches will accompany the outbreak over parts of the valleys and Southeast through Sunday.

Three waves of severe weather are expected in Mississippi this week and strong tornadoes, large hail and damaging winds are possible.

A multi-day outbreak of severe thunderstorms will begin today and last through the weekend in the Midwest, South and East. Strong, long-tracked tornadoes, widespread damaging winds, large hail and flash flooding are all threats this dangerous bout of severe weather could produce.

The impacts are already beginning in some areas while preparations are being rushed to completion in other regions, so here's the very latest on everything: Severe thunderstorm winds are no joke—they account for 70% of all severe weather reports and can be just as destructive as a tornado.
