Is the lake breeze gonna give us an appetizer here in the Calumet before the entree later this evening?

Watch out for more of WI now:

Seems strange they didn’t push the watch to the lakefront counties. Maybe they will extend it later or just hoist warnings for them if necessary.

How many rotations are tucked into this thing anyway? Near Iowa Falls

 

[Malacka11]

Walking the dog and watching this little Batavia cell organize. It's actually really neat to see in person and on radar

Three (at least) distinct areas of broad rotation on the line

Interesting set up out here. Remnants from the early convention never totally cleared out. It got up to 90 but the at-home thermometer is down to 84. Overcast and a clam wind. Storms trying to fire along and south of US 30 in Indiana. 

[Harry Perry]

Still a good cap here… lake breeze just pushed east of here. 

[Malacka11]

I think I'm just baked but this little DuPage cell has some supercell-esque updraft presentation in person, I wish I could get a picture of the entire thing but I'm too close.

Good photo but what is that reflection in the upper right?

[CheeselandSkies]

Tornado warning in SW WI.

[CheeselandSkies]

If it can hold together and this SW WI cluster doesn't totally sap the energy for it, that other cluster N of La Crosse should be what eventually gets to Madison.

[CheeselandSkies]

2" hail reported in Platteville.

Weirdest severe thunderstorm warning polygon ever just issued from the Dubuque area eastward into Jo Daviess County, IL.

Whoever drew that up be smoking something bomb as hell.

I would believe that’s the cap breaking. 
 

Just the vents in my truck lol.

What did I say about supercell-esque updraft that shit literally exploded overhead

Severe Storm Watch, Flood Watch, Special Weather Statement, and storms in Kane County popping up in last 15 minute. It's on...

[Harry Perry]

Looks like the HRRR sniffed out something, but looks like garbage over this way for tonight. Wonder what the next SPC outlook will look like. Almost looks as though storms are firing along the higher dew point gradient from N IL points southeast into Indiana. 

Dare I say… this mornings bullshit in Indiana forked SWMI once again by working over the atmosphere creating a rather large cold-pool, and only slowly advanced that cold-pool NE into the area while better untapped air pushed into northern Indiana? 
 

Time will tell. 

 

Already cooling off here @79° and clear skies.

Firing right along the back door cold front from the lake as it marches west

There you go Malacka

Dupage co looking prime to train

[SchaumburgStormer]

That line near Jo Davies co could mean business if it continues to mature

       to 80 mph possible
     Isolated large hail events to 1.5 inches in diameter possible
     A tornado or two possible

   SUMMARY...Initial supercells appear to be growing upscale near the
   Mississippi River and should accelerate east-southeast across much
   of northern Illinois tonight.

   The severe thunderstorm watch area is approximately along and 65
   statute miles north and south of a line from 40 miles south
   southwest of Cedar Rapids IA to 85 miles east northeast of
   Marseilles IL. For a complete depiction of the watch see the
   associated watch outline update (WOUS64 KWNS WOU2).

   PRECAUTIONARY/PREPAREDNESS ACTIONS...

   REMEMBER...A Severe Thunderstorm Watch means conditions are
   favorable for severe thunderstorms in and close to the watch area.
   Persons in these areas should be on the lookout for threatening
   weather conditions and listen for later statements and possible
   warnings. Severe thunderstorms can and occasionally do produce
   tornadoes.

Yet another tornado warning, on the MS River near St. Donatus, IA. Velocity looks like this one could do something.
