Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
828 AM EST Saturday, January 21, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Tonight, low pressure will exit the southern Rockies and develop
eastward across the southern plains. Initially, this will draw Gulf moisture
over the southern states, but later on Sunday, this will begin to lift north
into the Ohio Valley. The low will gradually move eastward and up into the
mid-Atlantic states Monday.

Later next week, the ridge that had been holding over the southeastern states
will break down and be replaced by a trof. This will result in cooler and
drier conditions through the end of January.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding is forecast or occurring across much of the western basin.
Additional flooding is possible in portions of Indiana that haven`t yet reached
flood, but elsewhere flooding isn`t likely.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain affected mainly the northeastern half of the Ohio Valley. Basin average
amounts were generally 0.25 inch or less.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rainfall is expected basinwide. Amounts will increase to the south. Basin
averages will range from 0.75 to 1.25 inches in southern and eastern Kentucky,
southern West Virginia, far western Virginia and middle Tennessee.
