If you have been paying attention to the weather over the past couple of days, you know that we could be in for some major storms Thursday evening. So this is what we're looking at so far:Most of Thursday should remain dry, however, it is going to be very windy and warm. Winds (non thunderstorm winds) could possibly gust to 50 MPH during the afternoon. An intensifing area of low pressure in the Plains now will move east tonight and tomorrow. It will bring a cold front through Iowa where the potential for supercell thunderstorms (ones that could produce tornadoes) will likely develop during the afternoon. As the evening progresses, the storms will form into a squall line, where the main threat for us will be damaging winds, although hail and isolated tornadoes will not be ruled out. The thing to keep in mind with this is that we will have very gusty winds through all the layers of the atmosphere so as quick as the storms moved in, they will be quick to move out as well.
As we continue to go through tonight and tomorrow morning, we will continue to keep you updated on air and right here on our blog. Feel free to post your comments as well! - CANDY

Why does the NWS have a wind advisory for IL but not for WI?
Does that mean it is expected to be less windy in WI or is it just different NWS offices with different opinions?
Just differing opinions. As far as wind advisories, (if I was at the NWS) I would wait to issue them because you can't "prepare" for wind. I anticipate that everyone will be under one tomorrow.
Look at how many Wind Advisories are posted! Amazing

Will we just see one line at night and thats it or could there be other smaller storms?
The magnitude of this system is quite amazing. The wind has already picked up significantly in the past few hours. It's going to be a very excitng day tomorrow for you guys in the weather center. Not that any of you have any control over tightening down the ropes on your tower out there... but I don't know what I would do without WREX broadcasting the severe weather information..:o) A quick question for you: is it true that if we see more sunshine tomorrow that the severe weather threat will be maintained at a higher level -vs.- cloudiness decreasing the threat?
I've heard eric talk about that quite a few times, that sunshine will increase instability (I think thats what it does, so dont quote me on it) and make the chances for severe storms higher.
Certainly the more sunshine we see the more unstable the atmosphere becomes.
Think of it in this hypothetical situation. Let's say the air high up in the atmosphere is 88 degrees. Unless the air near the surface reaches a temperature higher than that we won't see any rising air. Warm air rises, but if there is a "cap" on it (warmer air aloft), nothing will happen. In conclusion, the more sunshine we see the warmer the air near the surface will become.
Eastern Iowa needs to see a lot of sunshine today for our severe weather to come to fruition.
