Update: Showers/thunderstorms moving east through the Chicago area this evening
As low pressure passes through our area, shower and thunderstorm bands have become more north-south oriented with locally heavy downpours in some of the stronger storms. Rainfall of 1 to 2-inches will be possible in some locations before rain gradually diminishes from the west later tonight.
The current weather radar mosaic displayed below shows eastward-moving showers and thunderstorms developing north of a west-east-oriented warm front laying across central Illinois. A Severe Thunderstorm Watch is in effect for southeast Iowa, northeast Missouri and west-central Illinois until 8PM CDT this evening, and severe storms are more likely to spread into our area and develop along and north of the frontal boundary here later in the afternoon or early evening.
Locally heavy downpours, vivid lightning and gusty winds will likely occur with some of the stronger storms in our area this afternoon.
