The low pressure system is forecast to move slowly northeastward
across the Ohio Valley tonight through Sunday and will move into
the lower Great Lakes by Monday. The low combined with tropical
moisture will continue to cause heavy rain across the Ohio Valley
today and will spread into portions of the Lower Great Lakes and
Mid-Atlantic region by 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 PM CDT. Please refer to your local National Weather
Service office for additional information on this event.
