Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1142 AM EST Friday, January 20, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
A warm front will continue to lift through the northeastern Ohio Valley today.
Rain will will move out of the basin later today.

By Saturday night, 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 all but the far northeastern Ohio Valley. Heaviest basin averages
were in the 0.75 to 1.50 inch range in eastern Illinois, much of Indiana,
western Ohio, middle Kentucky and middle Tennessee.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast across much of the area, but basin average amounts will be
light. amounts will approach 0.25 inch only in the northeastern and far
southern Ohio Valley.
