Friday Forecast

Friday: Today is looking really warm. Temps this morning will be around 50. Temps will rapidly rise in the afternoon to near 80. Winds will be 15-20mph with gusts near 40. Thunderstorms are possible this afternoon. Some of these thunderstorms may be severe (more below). Thunderstorms will move through the area tonight. Temps will fall into the mid 40s by mid night tonight..

Severe Weather Threat This Afternoon: There is a threat for severe thunderstorms later this afternoon and evening. Based on the latest model runs, thunderstorms will begin to impact our area between 3-6 this afternoon.Thunderstorm initiation looks to be as early as 2 and as late as 4. The earlier the initiation, the more time the storms have to obtain energy. CAPE (instability) values will range from 1000-2000J/Kg. A decent amount of wind shear will be in place later this afternoon. This will allow for rotating storms or super cells to develop. This will heighten the risk for large hail and an isolated tornado. I will update on the severe weather threat when I can. The Storm Prediction Center has us under a SLIGHT risk area today with a 15% chance for large hail and damaging winds and a 2% chance of a tornado within 25 miles (very small). South Eastern Indiana has a 30% chance for large hail and damaging winds and a 5% chance of a tornado with 25 miles of a point. The next update from the Storm Prediction Center is 12:30. I will update if they and the new model runs have new information.
