Today/Tonight's Severe Weather Update

As of 8AM Wednesday morning, a few showers have made it into northwestern Ohio. Most of this rain is outrunning the energy associated with the large scale cluster now developing in the upper midwest.

CURRENT RADAR LOOP IS HERE

The Storm Prediction Center still has western Ohio under a MODERATE risk of severe weather. Remember that the definition of a SEVERE THUNDERSTORM is a storm that has 58 mph winds or greater and/or hail of at least 1 INCH in diameter. 

* Moderate risk for western Ohio *

Wind damage will be the biggest threat along with heavy rain tonight

Any showers and storms that develop ahead of the main cluster this afternoon will be more scattered. Not everyone will see rain and storms this afternoon and early evening. That said, we will need to keep a careful eye on this. Often times, these scattered, fast-moving storms in the late afternoon can rapidly develop into organized clusters by themselves. In fact, one computer projection is showing just that but not until the mid evening.
 

The last complex of rain and storms overnight will be heavy. Rainfall will be significant. Winds will be pushing 30+ mph in spots.
