Severe threat over for now...

The storms that blew up over our area early in the afternoon have left, leaving the severe thunderstorm watch cancelled.

There were many trees and power lines down over highways in Corydon, IN, and power lines also down in West Point, KY.

Let me now explain the situation for tonight...

The storms have ended for now. We may get an isolated pop up during the early evening, but no severe is expected.

Our next chance of severe will be after 10pm tonight. A storm complex developing over northern Missouri and central Illinois will move southeast towards our area during the night time hours. The storms will produce lots of wind damage over these areas, but they may weaken some as they move towards southern Indiana and north central Kentucky.



For this reason, west of I-65 is in a 30% chance of wind damage, and east of 65 is now in a 15% chance. However, notice that the 45% hatched area goes to western Indiana. The question is how soon and how much they will weaken after they move into Indiana.

Remember last night when the storms seemingly exploded when the sun went down? That was because of how hot it was. When it is that hot, it caps the atmosphere and won't let storms develop. So, the sun is out and it is heating up again. Our humidity in place will help to destabilize the atmosphere. This may lead to the same thing as last night; the storms continue on through the night, still remaining severe.

I will probably again around 9:15pm...
