Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
113 PM EST Thursday, January 19, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Two significant weather events, one already starting to push into the region,
and a second early next week to affect mainly the southeastern basin.  The trend
for this second system looks to be farther south and weaker than previous
forecasts.  Cold weather later next week will curtail additional hydrologic
impacts to the Ohio Valley.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding is forecast or occurring across much of the western basin.  New
flooding is also a threat with the expected rainfall through Friday.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light rain amounts were observed in the Appalachians yesterday, and in the
southwestern basin early this morning, otherwise, the Ohio Valley was dry
in the past 24 hours.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Forecast rainfall amounts exceed 1.5 inches in the southwestern basin with a
widespread inch or so expected northward through much of Indiana.
Amounts in the eastern basin will be minimal as the system weakens by the
time it reaches there.

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