After an excruciatingly hot start to July, we will see some relief today in the form of cooler temps and a northerly breeze. Air spilling southward out of the UP will pass over the Great Lakes, remaining cool the entire time. This will cap temps this afternoon around 78F in the Chicago area. HEAVEN!! Skies will generally be partly to mostly cloudy.

Unfortunately the cool weather is not sticking around and an approaching frontal system tomorrow will coax temps back up to around 90F. Dew points will rise, accordingly. 

Generally seasonable temps with a chance of an isolated afternoon thunderstorm will become the norm for the next week or so. 

If you are curious - the first 6 days of July 2025 have averaged more than 6 degrees above normal! For our most “stable” month, temperature-wise (July normally has the least fluctuation from the “normal”), this is quite extreme. (The hottest July on record saw monthly-averaged temps barely 6 degrees warmer than the normal, for reference).

Tl;dr - cool air relief today! High 78F. But heat returns tomorrow. 80s - 90s expected for next 7 days.
