Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1217 PM EDT Sunday, May 17, 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. With the exception of a weak system
around midweek, generally dry conditions are forecast.

...FLOOD POTENTIAL DISCUSSION...
Despite the continued unsettled weather the next couple days, the potential
for river flooding will remain relatively low.  No widespread excessive
rain is expected. Locally heavy rains may result in some flash flooding,
however.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms were scattered throughout the region. More
concentrated activity fell in OH, southwest PA, western KY, western TN, and
east-central IL. Amounts in these enhanced areas were generally in
the 0.50" to 1.50" ballpark with locally heavier amounts to 3.00".

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms are forecast throughout much of the basin. A
large portion of the Ohio Valley will see 0.50" to 1.00" with locally
heavier amounts possible.  The northwest quadrant should see lesser
amounts, under 0.40" on average.

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