Showers/thunderstorms spread into Chicago area
A band of scattered showers and thunderstorms will continue a southeastward movement into the immediate Chicago area late this Wednesday morning and the possibility of additional shower/thunderstorm development will exist this afternoon. It appears that most of the activity will occur north of the Interstate-88/290 corridor including Chicago with more isolated showers/thunderstorms farther south. Some gusty winds and small hail are possible with the strongest storms, otherwise brief heavy rain and lightning can be expected.
The upper-level disturbance that triggered a broad area of thunderstorms overnight in Wisconsin will continue to move east-southeast into Lower Michigan later today. Northern Illinois is positioned on the southern edge of this shower/thunderstorm activity, which should end from the west here later this afternoon.
