Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1152 AM EDT Monday, September 1, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
Humid and warm southerly flow continues to bring occasional bouts of showers to
assorted areas of the Ohio River valley.  These will continue through the course
of the day today and into the overnight hours.  Tuesday will see a cold front
pass through the basin bringing widespread showers and thunderstorms as it
traverses the area.  Behind that, cooler and drier high pressure will take its
place for a day or two before humid air returns to the basin late in the week
and into the weekend.

...FLOOD POTENTIAL DISCUSSION...
Flood potential is currently low. Chances for localized flooding/flash
flooding will increase with the widespread showers and thunderstorms with the
passage of the cold front on Tuesday.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Many areas of the Ohio River forecast basin saw some precipitation over the past
24 hours, though the majority was on the light, a quarter of an inch or less,
side.  There were a few very small, yet concentrated cores of showers that
yielded multiple inches.  There was a 4 to 5 inch core in Greene county of Ohio.
Also, there was a two to three inch core in eastern KY as well as a 2 inch core
in SW New York.  Again, all very small and localized.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Widespread precipitation is forecast for the next 48 hours.  Heaviest
basin-average amounts total just over an inch in Indiana, eastern IL, and
northwest OH.  Most other areas measure a quarter to a half inch basin-average.

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