Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1237 PM EDT Saturday, July 22, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Warm and very humid conditions continue in the Ohio Valley. Showers and storms
will continue to affect the basin, with an axis of most significant activity
today from the northwestern portion of the basin eastward into the east central
Ohio Valley. Storminess will gradually drift southward, more significantly
affecting areas south of the Ohio River on Sunday.

By Monday and into Tuesday a slightly cooler and drier air mass will settle
into the Ohio Valley.

Another cold front with associated showers and storms are expected to push
south through the basin sometime towards the end of next week.

...FLOOD POTENTIAL DISCUSSION...
At the beginning of the weekend no river flooding was occurring in the Ohio
Valley. Recent and forecast rainfall are expected to produce some minor
flooding in portions of western Indiana by the end of the weekend. And heavy
rainfall from thunderstorms can produce localized flash flooding anytime.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell mainly along a band from northern Illinois, across all but southern
Indiana, into most of Ohio, northeastern Kentucky and in West Virginia. Basin
averages were heaviest across northern Indiana and portions of Ohio where they
ranged from 0.50 to around 2.00 inches.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast across the entire area, but amounts ranging from 1.00 to 2.25
inch are forecast to southeastern Ohio, southwestern Pennsylvania and most of
West Virginia.

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