SEVERE THUNDERSTORM & EF2-EF5 TORNADO RISK 3/19/2025

STATES INCLUDE ILLIONIS, INDIANA, WESTERN OHIO, NORTHWEST KENTUCKY

Today, a powerful fast-moving storm system is moving out of the Central Plains and toward the Great Lakes, accompanied by a cold front to the south.

The storm system proved to be stronger than expected, and as a result, the National Weather Service’s Storm Prediction Center raised the risk level to “enhanced” in parts of Eastern Illinois and Western Indiana, while expanding the “slight” risk area to include much of Illinois, Indiana, Ohio and Kentucky.

It has also expanded and increased the tornado risk to 10%, which includes the enhanced risk zone. The hatched area on the map above indicates areas where thunderstorms could produce winds of more than 65 mph and tornadoes rated EF-2 to EF-5. An EF2 tornado can reach 115 mph or higher and leave a path of destruction.

The European model shows the track of a developing low in Northwest Missouri that heads to the Great Lakes tonight and Thursday. West of the low track we have heavy snow and blizzard conditions from Northwest Iowa to northwest Wisconsin and the upper Peninsula of Michigan.

East and south of the low is where the warm sector lies and in this zone which extends south into Tennessee Mississippi & Alambama we have a marginal risk for isolated severe thunderstorms.

This storm system is not expected to produce a widespread severe weathter and tornado outbreak like we saw this past weekend in the Midwest & Deep South. Thunderstorm risk will shift eastward Thursday to parts of the Mid Atlantic but severe weather is not forecast at this time.
