Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1238 PM EST Tuesday, January 24, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
High pressure is gradually building into the Ohio Valley, though some showers
are lingering over the eastern basin. This activity is forecast to diminish
overnight as the high strengthens. A cold front will eventually enter the
western basin Wednesday, bringing another round of widespread, albeit light
rainfall.  Behind the front, temperatures will drop back to near normal
levels accompanied by scattered, light snow showers the rest of the week
into the weekend.

..FLOOD POTENTIAL DISCUSSION...
Recent rainfall events have resulted in minor flooding across a large
portion of the western basin, and with additional rainfall earlier this
week, some significant but sub-flood rises are also forecast/occurring across
the eastern parts of the Ohio Valley. With a return to more winter-like
conditions (colder/drier) the flood potential will gradually diminish
the rest of this month.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Moderate to heavy rain fell across parts of the basin, including the
north-central, eastern, and southeastern portions. Amounts in these areas
generally ranged from 0.50" to 1.50". Outside of these areas amounts were
generally 0.10" to 0.50" except the western third of the basin which was
completely dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light rain (eventually transitioning over to a wintry mix of rain and snow)
will produce a few hundredths in most places, but as much as a third of an
inch in the Lake Erie snowbelt and higher elevations of WV.

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