Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1019 AM EDT Monday, May 18, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
A moist, southwesterly flow pattern will fuel scattered showers and
thunderstorms throughout the Ohio Valley into late Monday. A cold front
will work through the basin Monday night ushering in a cooler, drier
airmass for much of the upcoming week.

Another cold front is forecast to push southward through the Ohio Valley around
Wednesday and Wednesday night. This front will feature limited moisture, so
rainfall amounts are expected to be lighter than the current system.

The remainder of the week and into the weekend is expected to be dry. Not until
Sunday does moisture begin returning to the Ohio Valley.

...FLOOD POTENTIAL DISCUSSION...
Though rains will be widespread over the next 24 hours, amounts are not
expected to be excessive. Flood potential remains low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms were scattered throughout the region. Heaviest basin
average amounts fell over portions of far southern Illinois, western Kentucky
and middle Tennessee where they ranged up to around 1.75 inches.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected everywhere except for the far northwestern corner of the Ohio
Valley. Amounts will generally increase to the southeast with the heaviest axis
of rainfall ranging from 0.50 to 0.80 inch from middle Tennessee, through
eastern Kentucky, all of West Virginia and into southwestern Pennsylvania.

...RIVER BASINS IN FLOOD...
None.
