Yes indeed, this is all going to occur here without hardly any heating. So far it is mostly cloudy, but if we are able to get some sun to heat up this area it could be even worse. I'm going to be keeping an eye on it, especially since it's the labor day party time and it's going to storm

Looks like KC is on the edge of the slight risk core. In all honesty, I haven't really paid attention to the local forecast since I have been following Hurricane Frances.

We'll see what the SPC does with this in about 15 min with the next outlook. Then I'll try to get an updated post on the new outlook

[NWIASpotter]

It looks like everything is much the same, still the same probablities. Still watching about the lack of heating, but there should be plenty of vertical shear to get those storms supercellular if they get going.

the weather dude in Eau Claire, WI said a tornado was spotted a little while ago in St. Croix COunty (EAST OF THE TWIN CITIES, i believe)... I'm south of here, but watching them progress Eastward, looks pretty impressive on radar....

[NWIASpotter]

We had a good amount of tornado warnings around here, only one was reported on the ground. A lot of rain, they weren't very impressive on radar, but they had a lot of shear with them.
