Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1141 AM EDT Sunday, July 23, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Conditions remain unstable across the Ohio Valley due to very warm and humid
conditions. Showers and storms are expected over much of the Ohio Valley today.
A cold front will push southward through the region tonight and Monday pushing
storm activity south with it. Behind the front a slightly cooler and drier air
mass will settle into the region.

Another cold front with associated showers and storms is expected to push
south through the basin sometime towards the end of next week.

...FLOOD POTENTIAL DISCUSSION...
some minor river flooding was occurring in western Indiana and isolated minor
flooding in northern Ohio. The potential for additional flooding in western
Indiana is high as rain continues and minor flood waters proceed downstream.
Additionally, heavy rainfall from thunderstorms can produce localized flash
flooding anytime, especially in areas receiving repeated rainfall events.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell over all but the far southwestern Ohio Valley. Heaviest basin
averages resulted from storms that generally affected areas just north and
south of the Ohio River. In these areas basin averages ranged from 0.50 to 4.00
inches, with some isolated areas in southern Indiana and northern Kentucky
measuring 5 to over 7 inches.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast across the entire area. Heaviest basin average amounts are
forecast for middle and eastern Kentucky and West Virginia where basin averages
will range from 0.50 to 1.20 inches.

...RIVER BASINS IN FLOOD...
