Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
112 PM EDT Wednesday, August 17, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
A front that had remained relatively stationary across the Ohio Valley for the
last several days has begun to weaken and sag southeastward through the region.
The deepest moisture and therefore most of the showers and storms will drift
southward with the front.

Another front will approach from the west late in the week. It is expected to
pass through the basin Sunday. Widespread precipitation will develop ahead of
and along the front. Behind the front next week conditions are expected to
shift to cooler and dry.

...FLOOD POTENTIAL DISCUSSION...
Flooding is currently forecast in eastern IL and southern IN. Various points
in the Little Wabash Watershed are currently in or forecast to reach moderate
flood levels. Minor flooding of other large rivers in the western basin will
likely persist through the week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
While rain fell over most of the Ohio Valley, the heaviest band was oriented
from western Kentucky and southern Illinois, across southern Indiana and
southern Ohio into southwestern Pennsylvania where basin average amounts
ranged from 0.50 to 1.50 inches.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected over all but the west central Ohio Valley. Basin averages will
be heaviest in eastern Kentucky, southern Ohio and much of West Virginia where
they will range from 0.50 to 0.75 inch.
