>The storms in Chicago fell apart last night and lost their severe characteristics.
The reasons why are interesting:
-A cap redeveloped, slightly suppressing storms.
-CAPE values fell, making the atmosphere unsupportive of severe storms
-Lapse Rates were unsupportive to begin with.
All in all, after a couple of cells, a very light cap redeveloped around Chicago. As that happened, storms that moved through were killing the CAPE values, thus stabilizing the atmosphere.
Just as a reference, I posted all those images but that never came to. I will post worthwile information from now on.
But the first outbreak gets you excited like that.
