The low pressure system is forecast to move slowly northeastward
through the Middle Mississippi and Ohio Valleys over the next few
days. The low combined with tropical moisture will continue to
cause heavy rain in eastern portions of the Middle Mississippi
Valley today. Heavy rain is likely in the Ohio Valley through the
weekend and will spread into portions of the Lower Great Lakes
region on Sunday. Additional rainfall totals of over 5 inches will
be widespread throughout those regions, with locally higher
amounts. Flooding and flash flooding are likely, and a high risk
of excessive rainfall is in effect for Saturday and Saturday night
for parts of Illinois, Indiana, and far western Ohio.

The next storm summary will be issued by the Weather Prediction
Center at 1000 AM CDT. Please refer to your local National Weather
Service office for additional information on this event.
