Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1147 AM EDT Tuesday, April 15, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
A cold front will continue eastward today and exit the Ohio Valley by late
morning. Some snow showers will linger into the afternoon, in the eastern
mountains and in some lake effect prone areas, but otherwise conditions will
dry out. Dry conditions will continue until at least Friday. At that time a
weak wave will move through the basin providing some light precipitation. It
will not be until early next week that we see a return of more significant
rainfall.

...FLOOD POTENTIAL DISCUSSION...
Minor to moderate flooding remains on the lower parts of the White, Wabash,
Little Wabash, and Ohio Rivers.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Precipitation fell across the entire Ohio Valley. Heaviest amounts were
oriented along a band from middle Tennessee, through middle Kentucky, much of
Ohio and far northwestern Pennsylvnia where totals ranged from 0.50 to 1.25
inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Nearly all of the precipitation is forecast to fall during the day today.
Amounts increase to the east with basin averages close to 0.50 inch along the
eastern edge of the basin. Measurable precipitation is forecast in eastern
Tennessee, eastern Kentucky, central Ohio and all areas farther east.
Additionally, some very light lake effect snow accumulations are expected to
continue in portions of Indiana.
