While not cold, it is much cooler this afternoon than yesterday, about 20° to 30° cooler over northern IL & northwest IN. This cooler air surged in last night for much of the Midwest. In Nebraska, temperatures are over 50° cooler than yesterday! #ILwx #INwx pic.twitter.com/AoDDEEWB21

Numerous waves of heavy rainfall are possible across the Upper Midwest over the next 5-7 days. Although it is too early for high confidence in precipitation amounts, 2-4 inches of rainfall, with isolated higher values, are possible by Tuesday morning. pic.twitter.com/iMaw6cG6t5

Photo here from Michigan City, IN late this morning. While beyond typical beach season, we know walking the immediate lake shore can still be a fun autumn activity. Use caution through this evening along IL & IN shores, with waves briefly near 10 ft. #ILwx #INwx pic.twitter.com/6qpNkC1maN

Rainfall amounts of 0.5-1.5 inches are forecast across the upper portions of the Rock River and Fox River basins through Saturday morning. This rainfall is expected to cause additional rises with minor flooding possible. pic.twitter.com/ttZZhJ4YmE
