maybe they figure the duration will be really short as the front pushes through in a few hours

 

Good question. It's not like the heat index's are that much different from west to east. Although the dewpoints are higher over the agricultural lands more so.

Not long enough of a period of time for the heat index to exceed 100°?

My only guess is they watched trends until it was clear cut that dews were not going to mix out and by then it was too late. Maybe.

That is an impressive looking cell.  Looks like it's going to miss the city just to the west, though.

 

You're under a warning now. Line is back building.

I grew up without AC and only have had it for the last 8 or so years. Just one of those things where you are used to it. Keep the house closed during the day and use fans to get the hot air out at night. Only can remember a few times where it was unbearable, 1995 being the worst I can remember because it didnt cool off at night, but I was young so easier to deal with. I still only set my AC at 78.

The temp in our house ranges between 72F and 75F...  I was at my brother's (who lives in Rochester, MN) and their house  (brand new condo) was 70F and i was freezing.   In winter i easily can handle 65F...  just need to get used to it...  I just couldn't imagine living without AC.  

 

Saukville claims to not use his...

 

Above 90F again...dews dropped to upper 60Fs...clear blue skies.

hi-res nam did pretty well a couple days out

 

Yeah the 12z run was slow with the frontal passage. Looking good for that storm to pass through here.

 

DLL - maybe the hotter air got trapped in the valley overnight? Not much mixing?

 

95/102 here right now.

 

Waukesha, Brookfield getting slammed. Probably some hail on that end of the storm falling.

I don't know if CR hit 100 intra-hour.  Des Moines hit 104 last hour.  Beyond the temps, the dewpoints are interesting.  Ottumwa is currently 101 with a dewpoint of 58.  I'm assuming dry air has been mixing down.  Just up the road in Waterloo the temp is 92 with a dewpoint of 77 due to moisture pooling along the front.  That's quite a difference.

Severe thunderstorm warning now for Lake County, Mc Henry county for quarter sized hail and 60mph winds.

 

First pic:

 

 

Looks like a hail core near Union Grove, WI. About 20 miles NNW of here.
