Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
120 PM EDT Friday, July 24, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
High pressure building into the Ohio Valley will keep things dry in the Ohio
River forecast basin for the next couple of days.  On Sunday, a weak cold front
will approach and enter the area from the northwest.  This front, however, will
have little moisture associated with it so only some areas of light, scattered
showers will fall across the northern basin.  After this front, the beginning of
the week will see more ridging building back into the midwest and hot and humid
air.  Monday night into Tuesday carries some chance of a convective system swath
through the western basin.  The ridge soon will strengthen more and keep the
basin dry through the second half of next week.

...FLOOD POTENTIAL DISCUSSION...
Flood potential will remain elevated due to existing flooding. New flooding is
not likely for the foreseeable future.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
The far southern basin received some areas of showers and thunderstorms over the
past 24 hours.  Heaviest totals were in a small two inch core in south-central
Kentucky.  Other areas of TN and southern KY saw about a half inch to one inch.
The rest of the basin was dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light amounts of a tenth or two of an inch or less were forecast over the
northern fringes of the basin for Sunday morning.  Otherwise, zero for most of
the basin.

...RIVER BASINS IN FLOOD...
Points along the following river basins were in flood Friday morning:
