CHICAGO, IL — The city wakes under a pale autumn dawn, car roofs glinting with frost and wisps of vapor lifting from backyards and rail yards alike. The chill cuts quickly this morning, reminding residents that fall is almost spent — and winter’s edge is quietly waiting beyond the weekend.
According to the National Weather Service in Chicago/Romeoville, patchy frost will fade by midmorning as skies clear and temperatures climb toward 53°F. Northwest winds near 5 mph will keep the air crisp but manageable, and sunshine dominates the afternoon. Away from the lake, significant frost risk remains for rural and suburban areas into early Saturday morning.
Saturday stays mostly sunny, with a high near 54°F, before clouds and spotty showers move in by afternoon and evening — mainly west of the I-55 corridor. Sunday will see mild highs in the upper 50s, though a 20–30% chance of light rain lingers for Chicago and northwest Indiana.
By Monday, skies dry out again with highs near 56°F under mostly sunny conditions. Nights remain cool — lows dip into the mid-40s, and frost could return briefly midweek as another weak front passes.
To be fair, the next few days offer a manageable mix — bright skies, chilly mornings, and just a touch of rain. Long-range models even hint at a more wintry setup arriving after Halloween, signaling the first true cold snap of November. For now, Chicago gets one last stretch of pleasant, crisp fall weather before the next seasonal turn.
