Freeze Watch Issued for Part of Chicago Area This Weekend

A Freeze Watch is expected to take effect late Friday night in LaSalle County

Enjoy it while it lasts, Chicago. Thursday’s mild temperatures might be the last for a while.

Temperature highs are expected to peak early Friday morning before dropping nearly 30 degrees in a matter of hours as a powerful cold front makes it way into the area, bringing a Freeze Watch for some heading into the overnight hours.

The cold weather will move in from the west, sending temperatures on a steady but dramatic drop from the 60s in the early morning to the 30s by the evening.

A Freeze Watch takes effect beginning at 2 a.m. Saturday in LaSalle County, continuing until 9 a.m. Temperatures are expected to reach sub-freezing lows, dipping into the upper-20s and low-30s, which could kill uncovered sensitive plants and vegetation outside, the alert warns. 

Rain is expected to continue from Thursday evening through Friday afternoon as winds pick up. 

Temperature highs Saturday sit in the upper-40s and near 50 degrees, though a windy and chilly afternoon will make it feel colder.

The Bank of America Chicago Marathon will likely see temperatures in the upper-30s and low-40s at the time of the race’s start, with wind chill readings near 32 degrees.
