It doesn't look as though this weeks damage was anywhere near as bad as last Friday's. As far as I know there are no assessment crews from the National Weather Service surveying storm damage even though there were reports of funnel clouds and some touchdowns. There doesn't seem to be extensive damage. There was quite a bit of microburst damage south of Fort Wayne in Adams county though.

Large Squall Line Moving Toward Area
Remember that squall line I mentioned this morning. Here it is, this is very elongated but with the wind and the afternoon heating it won't take much to spark some pretty decent storms.

Severe weather tonight?
A line of storms ahead of front moves into the area tonight, does that mean severe weather for us? Well, there is certainly some dynamics for severe weather in place, the heat and humidity of the afternoon are going to add some buoyancy to the atmosphere and a boundary of low pressure will push a squall line of thunderstorms towards the area by late this afternoon and tonight. A strong low level jet will also be present. Here's my thinking, with squall line thunderstorms severe weather is limited by the fast movement of storms. Cumulonimbus cloud tops are cut off by this fast movement making for marginally severe storms. So, while there is a risk of severe weather, and I'm certainly on board with this, dynamics are marginal right now.
