Hydrologic Outlook
National Weather Service Lincoln IL
356 AM CDT Thu Apr 27 2017

...COPIOUS RAINFALL EXPECTED THIS WEEKEND...

A frontal boundary will become nearly stationary across southern
Illinois Friday night, and will begin to slowly drift northward
through Saturday night. A very moist air mass will be in place
during this period, resulting in occasionally heavy rain falling.
Current indications are that rainfall totals in excess of 3 inches
are likely over all of central and southeast Illinois before the
storm system exits Sunday night, with potential for over 4 inches
east of the I-55 corridor.

With this amount of rain falling, rapid runoff is expected to
produce river flooding, as well as localized flooding of area
roads. Be sure to monitor later forecasts for updates on the
potential for flooding this weekend.
