Warmth and rain on tap for Chicago
As low pressure strengthens in the Central Plains and its associated warm front moves north out of Central Illinois, there will be extensive low cloudiness and scattered dense fog early Monday morning. As the front moves into our area toward evening, moderate to locally heavy rains will spread from the south to the north. Overnight rains could give upwards of an inch at many locations.
The warm front will surge north of our area toward Monday evening, and temps will be on the rise overnight. Strong SW winds will boost readings to near record highs in the lower 60s on Tuesday. As the low pressure tracks across Michigan, the associated cold front will swing through our area from the west later Tuesday, temps falling overnight. Cold temps/snow showers likely Wednesday/Thursday.
- Strong 120 mph SW jet aloft to our west moving slowly east
- Strong SW low-level jet shifting just to east of our area
- Cool air spreading over Rockies/northern Plains
- Cold front will move through Chicago later Tuesday, preceded by record-warm air and followed by colder air/snow showers later Wednesday/Thursday
