First watch in almost 2 months for Chicago; ridiculous.

sad times, really.

2.07" of rain at ORD last evening/night and into early this morning.

paging hawkeye.

trash outlook.

not supported by cams or the environment.

finally some decent deep summer action around here.

nothing severe, but this is a step in the right direction.

Morning storms died to the west over Iowa, and this afternoon they're blowing up just east.  Gotta love it.

Hope we can cash in on the leftover Iowa activity later tonight.

look at the radar just west?

don't go all you know who on us.

Crazy localized!  Was it a backbuilding cell?

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.

Quite a flood event on the near west side early last night.

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.

Has the RRFS been doing pretty well?  I honestly haven't been paying enough attention to it as I probably should have lol.

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.

It hit 94° at ORD and 95° at MDW today.

Both locations were 89°'d yesterday, while all inland areas hit 90°+.
