Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1231 PM EST Friday, November 21, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
High pressure over the Ohio Valley today will move east and allow another
weather event to move into the basin.  This event will be mainly rain as warmer
air returns to the region, and most of the rain will occur on Sunday.  Colder
and drier weather will return for the work week with a chance of light snow on
Thursday.

...FLOOD POTENTIAL DISCUSSION...
The potential for flooding is will be on the rise starting Sunday.  The rain and
warm weather will melt any remaining snow, and the combined runoff will not soak
into the ground much.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow fell in the northeastern basin amounting to a half inch (of liquid
equivalent) in parts of that region in the 24 hours ending near daybreak today.

...72-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light rain will fall over much of the Ohio Valley until Sunday, but more
organized rain will move into the region early Sunday.  Amounts expected will be
over an inch in the northwest basin through the 3-day period.

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