Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
107 PM EST Saturday, February 13, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
Some Lake Effect snow showers from both Lakes Michigan and Erie will affect the
northern and eastern portions of the Ohio Valley today, though they will be
light. This activity should taper off from west to east later today as high
pressure moves across the basin.

A warm front will lift into the basin Sunday and Sunday night. This will bring
a mix of weather with snow in the north and a mix in the south.

Another stronger system will move across the southeastern Ohio Valley late
Monday into Tuesday. There is still some question as to where this low pressure
system will track, which can change which areas may get the heaviest rainfall
and where a rain/snow line will set up. It will be a complex system, but it
appears the heaviest liquid precipitation will be across the southeastern Ohio
Valley.

Another weaker disturbance will pass across the southern Ohio Valley on Tuesday
and Tuesday night continuing the chances of rain and snow.

Temperatures are expected to moderate to near or above normal by the end of
the week.

...FLOOD POTENTIAL DISCUSSION...
Frigid temperatures this weekend will give way to more normal temperatures next
week. Additionally, a series of disturbances will provide some liquid
precipitation, mainly in the south. This will result in some river rises, but
the potential for flooding remains low through the upcoming week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow showers affected most of the Ohio Valley. Basin average liquid-equivalent
amounts were ranged from 0.10 to 0.25 inches only in northeastern Ohio, far
western New York, portions of western Pennsylvania, southern West Virginia,
southeastern Kentucky and far western Virginia.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Precipitation is forecast across the entire Ohio Valley. Basin averaged liquid-
equivalent amounts will increase to the south with 0.25 to 0.75 inch forecast
across southern Kentucky, middle Tennessee and far southern West Virginia.

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