Good morning; the heat is ON. A supermassive dome of high pressure has slid eastward and is actively pumping muggy gulf coast air northward into the Chicago region. Dew points are already in the mid 70s and they will remain there through this week. 🥵

Mostly sunny skies under this dome will allow temps to skyrocket into the mid to upper 90s this afternoon. The only thing that could actively cap the max temp is the dew point itself. If the air is TOO saturated with corn sweat, it actually limits how hot it can get. Thats why, despite the strongest sun on the planet, the tropics rarely get above 100F whereas temps in the desert, much further north, less strong sun, but much drier air, regularly crests to 110+F. 

Anyways, the sunny, hellish weather will continue tomorrow through Thursday. All three days will see the thermometer inch close to 100F.

The heat will continue on Friday but a chance of thunderstorms could limit temps a smidge. Thunderstorms will continue through the weekend as temps gradually come back down to earth.

Tl;dr - heat wave is HERE. 90s-100 all week. Sunny. MUGGY. Drink water, stay in the shade.. Relief = t-storms Fri.
