Severe Weather Outbreak Today/Tonight

Widespread strong to severe thunderstorms will erupt this afternoon and evening. A severe squall line capable of all modes is expected. The Storm Prediction Center has issued a Moderate Risk for portions of Illinois, Missouri, Kentucky, Arkansas, Tennessee and Mississippi.

There is potential for strong tornadoes within the Moderate Risk areas. There is a hatched significant 15% threat in red, 10% hatched significant in yellow, 5% in brown and 2% in green.

There is a high probability of damaging winds as they have placed a hatched significant 45% threat in the pink outlined areas, 30% hatched significant in red, 15% hatched significant in yellow, 15% yellow non hatched, and 5% in brown.

Large hail is also of concern today with a 30% red and 15% yellow hatched significant.

For Central Kentucky:

Uncertainty exists due to current on going cloud cover. Depending on the rounds of showers and storms this afternoon should they occur, it will lessen the blow of the severe squall line that will sweep across the area of I-65 around midnight.

Should there be enough instability left over, all modes could be possible. The biggest threat at this time is 40 mph gradient winds outside of thunderstorms, a Wind Advisory had been issued. Regardless of the evolution, many of these storms will be nocturnal. Do not allow yourself to be caught off guard. If you have a basement, perhaps spend the night sleeping down there. Be ready to take shelter should a tornado warning be issued.

Wind Advisory

* WHAT...South to southwest winds of 15 to 25 mph with gusts to 40 mph possible.
