Severity: Severe. Certainty: Possible.
* WHAT...Flash flooding caused by excessive rainfall continues to be
possible.

* WHERE...Portions of Illinois, including the following areas,
Central Cook, De Kalb, DuPage, Eastern Will, Grundy, Kane,
Kankakee, Kendall, Lake IL, McHenry, Northern Cook, Northern Will,

* IMPACTS...Creeks and streams may rise out of their banks. Flooding
may occur in poor drainage and urban areas. Roads and streets may
be flooded.

* ADDITIONAL DETAILS...
- Showers and thunderstorms are developing along a stalled surface
front. Atmospheric conditions are favorable for heavy rainfall
with localized rainfall rates exceeding 2 inches per hour late
this evening through the overnight. Slow storm motion and the
potential for multiple rounds of rainfall will increase the
threat for flooding in some areas. Portions of northeastern
Illinois received 1 to 3 inches of rainfall earlier today which
also increases the threat for additional flooding.
