Showers/thunderstorms to pick up again later tonight into Sunday

Update 8PM CDT…

Shower/thunderstorm activity has diminished, but is expected to pick up again overnight, as another wave of showers and embedded thunderstorms spreads over our area from the southwest. Additional thunderstorm downpours are expected Sunday.


Update 4PM CDT…

The band of showers and embedded thunderstorms has become more southwest-northeast-oriented with individual cells moving east-northeast tracking over the same area. Should this trend continue, the band of precipitation will eventually become oriented west-east covering a good portion of northern Illinois into northwest Indiana – rainfall well in excess of an inch may accumulate at many locations. While the band is expected to slowly move north into Wisconsin tonight, additional development of showers/thunderstorms may occur along the southern edge, in effect keeping much of the Chicago area in periods of showers/thunderstorms into Sunday morning..


Update 12:20PM CDT…

The  eastward-moving band of showers and embedded thunderstorms will approach the immediate Chicago area early this afternoon – passing on east out over Lake Michigan and into northwest Indiana. Strongest storms seem for the most part to be south of Interstate-80 with expected wind gusts 30 to 40 mph, lightning and brief heavy downpours.


A north-south-oriented band of showers with embedded thunderstorms has moved east out of Iowa into western Illinois. The storms will likely be near the I-39 corridor by around noon. Brief heavy downpours, lightning and winds gusting to 30-40 mph can be expected with stronger storms.
