THURSDAY NIGHT: Mainly clear and warm for the season. Humidities remain comfortable. Lows range from the upper 50s coolest outlying areas to the upper 60s downtown Chicago. Winds: Light easterly. Low: 64.
Friday begins with a fair amount of sunshine but some clouds begin increasing as we move beyond lunchtime and into the later part of the afternoon.

An area of low pressure bordering Minnesota and the Dakotas is slowing moving to the east and will thicken area cloud cover by evening and also bring the chance for a spotty shower to 10-20% of the metro area.

Better chance of seeing more organized precipitation comes late Friday night and into Saturday.
Friday morning temperatures
A much warmer start to the day with much of the area in the lower to middle 60s.

Friday afternoon temperatures
Potentially one of the warmer days we see for the remainder of 2025! Highs again will surge well into the 80s for most of the area. The one exception will again be areas close to Lake Michigan where a light easterly breeze will keep highs a few degrees cooler in the upper 70s.

Friday boating forecast
Another day where area boaters may opt to leave work early or take the day off. Partly sunny skies expected with highs close to 80-degrees and only a modest 1-2 foot chop on Lake Michigan.

Friday sunburn forecast
