Chicago weather

THURSDAY: Smoky sunshine gives way to incoming clouds. A modest chance of a shower or t-storm or two developing—mainly inland. Warm but with a gusty cold front passage which sends temps tumbling beyond late morning. High 81—but falling back to the low and mid 60s by evening over much of the area and into the mid to upper 50s on the Lake Michigan shoreline before nightfall. THURSDAY NIGHT: Clearing, breezy and cooler. Low 54
