FOX 32 Chicago Meteorologist Mark Strehl says that temperatures overnight Sunday into Monday will drop into the mid- and upper-20s.
But on Monday, highs will make it into the low 40s with a very slight risk of light rain.
Tuesday will be a mix of a lot of clouds and a few peaks of sun with highs back near 42 and a 25% chance of rain later Tuesday night.
Wednesday will bring Chicago partial sunshine at times with highs in the mid 40’s.
There is a 50% chance of rain on Thursday, a 60% chance of rain on Thursday night and a 30% chance of rain on Friday. Both Thursday and Friday will have highs in the low and mid 40’s.
The 40’s will stick around for the weekend as well.
