conditions. A storm complex moving through the Great Lakes will sag southward
into the northern Ohio Valley late this afternoon and overnight. Scattered
showers and storms are expected to continue to drift southward on Friday.
A cold front will pass through the region late in the weekend with slightly
cooler and drier air behind it. Areal coverage of showers and storms will then
increase later next week.

Flood potential will remain low over the Ohio Valley this week.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
While rain is forecast for much of the basin, the scattered nature of the

Indiana, and the vicinity south of Lake Erie expecting 0.50 to 0.70 inch.
