Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1040 AM EDT Sunday, June 18, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Today and tonight a cold front will push through the Ohio Valley, producing
widespread showers and storms. This activity will end from northwest to
southeast tonight and into Monday.

Cooler and drier conditions will be the rule for the beginning of the work
week. A disturbance moving north of the basin Monday may produce some light
rainfall across the north. By mid-week temperatures will gradually moderate
to more normal levels.

Late in the week a front will begin to drop into the basin from the Great
Lakes. Over the next weekend the front will move through the basin, likely
interacting with deep Gulf moisture, resulting in very wet conditions.

...FLOOD POTENTIAL DISCUSSION...
Some river flooding is still forecast in western Indiana from recent rainfall.
Additional rainfall is not likely to produce any new river flooding in other
area.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell over the northwest quadrant of the Ohio Valley as well as along the
southeastern edge. Basin average amounts were highest in central Indiana where
they ranged from 0.50 to 1.50 inches.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast across the entire Ohio Valley. Basin average amounts will
generally increase to the southeast with amounts of 1.00 to 1.75 inches
expected in far western New York, western Pennsylvania, the southeastern half
of Ohio, much of West Virginia and western Virginia, eastern Kentucky and
middle Tennessee.
