Tornado Watch until 9pm
>> Wednesday, October 27, 2010
Storms are increasing in intensity in the Upstate into portions of the Piedmont. Looks like parameters are again in place for storms to rotate, and damaging winds and tornadoes will be the main potential. Looks like the actions will shift to near I-85 this time around...

Matt is the current sunshine going to make storms even worse than last night?
Well, the dynamics are slightly less impressive than yesterday, but yes, the sun is making things more unstable. They will likely balance out in some fashion.
Matt - I can't wait until when we get out of this humid and wet mess and get some dry and cooler air come in. It's been like this almost the whole week.
