Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
105 PM EDT Tuesday, July 21, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
..HYDROMETEOROLOGICAL DISCUSSION...
A cold front pushing southward through the Ohio Valley will keep rain confined
to the southern basin for the rest of the week beginning tonight.  For this
afternoon however, some shower and thunderstorm activity will redevelop behind
the front in the Appalachians area in the air that still has some humidity
leftover, but this too will wane as the humidity dries up.

...FLOOD POTENTIAL DISCUSSION...
Flood potential will remain elevated. Some new flooding is possible with some
locally heavy rains that have recently occurred..

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Most areas of the Ohio Valley, except the northern half of Ohio, had scattered
thunderstorm activity as the cold front passed through most of the area
overnight.  Isolated areas had over 2 inches, but most areas having rain were
well under an inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms will produce 0.25" or less in the Appalachians region
and in much of Tennessee into parts of Kentucky.  Little or no precip is
expected elsewhere in the region throughout most of the basin through Thursday
morning.
