Sunrise 7:01 AM MON OCT 13 2025  East 99° Sunset 6:12 PM MON OCT 13 2025  West 260° sunrise sunset azimuth chicago / Google Search   O’HARE FORECAST …  RADAR | CLOUDS  | UV Index | AQI |  RAIN | SNOW The same-day weather forecast for Monday degraded a bit from Sunday's forecast for Monday.

Radar indicates dissipating light rain precipitation moving west to east toward northeast Illinois from about I-80 into Wisconsin and about one-third the width of Illinois. Showers are forecast to end about 2:00 p.m. Monday. There was no rain in Sunday's forecast for Monday. If you want the technical excuse for this rain, warm advection ahead of an associated approaching surface cold front led to increased shower coverage, but dry air in the low-to-mid levels is preventing significant rain from hitting the ground. Next chance for rain is 1:00 a...
