Chicago, Illinois – Breezy conditions and spotty showers could move across central Illinois Friday afternoon, mainly near and south of U.S. Route 24, while the Chicago area stays mostly dry. A high swim risk is in effect for beaches along northwest Lake Michigan, where strong currents could make swimming dangerous.
According to the National Weather Service in Chicago, cooler-than-normal air will dominate the region through early next week. Highs Friday will only reach the mid-60s near the lakefront, with lows dipping into the low 40s overnight in outlying suburbs.
Saturday and Sunday will bring mostly sunny skies and dry conditions across northern Illinois, but the chill will linger. Highs both days will hover in the upper 60s, with overnight lows again falling into the 40s. Those planning outdoor events should prepare for sweater weather once the sun sets.
Travel impacts appear minimal, though drivers along U.S. 24 may encounter light sprinkles Friday afternoon. Beachgoers are urged to avoid swimming at unguarded Lake Michigan locations due to dangerous rip currents.
By Monday, temperatures are expected to rebound slightly into the mid-70s, but overnight lows will remain cool. Weather officials say the dry, stable pattern may continue through midweek.
