i should say, the enhanced is fine, it’s the placement that is horrid. way too far SE/E. there shouldn’t be a slight in the metro, let alone an enhanced nosing in.
It appears that a combination of a couple of factors lead to the setup...
An MCV was passing nearby (just south) and a weak front was moving through, which aided in the initial development of activity. There was also a lake breeze that was set up just inland, which appears to have had a [positive] effect on t'storm outflow attempting to push westward against a weak 10-20KT southwesterly LLJ that was in place, thus leading to the re-development and training of activity across that corridor.
Added a couple more 90°+ days over the holiday weekend. Hit 92° on the 4th and 94° on Saturday at both ORD and MDW.

The second half of June was phenomenal, temperature/humidity wise.
T'storm/severe t'storm wise, this first half of the year has been one of the worst I can recall for action around here.
ORD hit 90° on Saturday, 94° on Sunday, and 90° today. Midway wasn't even close on Saturday (Lake Breeze), but hit 93° on Sunday and 91° today.

It has had its ups and downs.
The biggest issue is that everyone looks at the simulated radar reflectivity output from it, which runs very hot, making everything look like a sup ready to produce the next EF-5.
