Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
244 PM EDT Thursday, September 29, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
A cut-off low pressure system will linger over the basin the next several
days. For the next 24 hours or so, deep moisture will stream up from the
southeast into the eastern basin, leading to some intense rainfall over the
Upper Ohio Valley. Moisture levels will then decrease this weekend and the
low will eventually begin pulling away on Sunday. Drier conditions will
prevail much of next week.

...FLOOD POTENTIAL DISCUSSION...
The flood potential will increase for the northern and eastern Ohio Valley.
No river flooding is forecast at this time, but the potential exists for
significant rises, especially across the Upper Ohio Valley. Any locally
heavy rainfall that develops could result in flooding and/or flash flooding.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell throughout much of the basin. Heaviest amounts fell in northern
KY, IN, and OH, where 0.25" to 1.25" reports were common.  Elsewhere
amounts were generally under 0.25" with only localized areas receiving
heavier totals.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Widespread showers and embedded thunderstorms will affect much of the
basin. Parts of the southern Ohio Valley will remain dry, but areas north
of the Ohio River can expect amounts greater than 0.50". Heavier totals in
eastern OH, western NY, western PA, and WV will range from 1" to 3" with
locally higher amounts.

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