Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1056 AM EDT Friday, April 11, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
By sunrise Friday morning, a cold front had pushed south and was aligned
generally across southern Indiana, through central Ohio and into western
Pennsylvania. This front will  continue to slowly drop through the basin,
passing to the southeast of the area on Friday evening.

A  warm front will develop over the basin Saturday and begin to lift north.
Other than some isolated shower activity the Ohio Valley will see dry and warm
conditions over the weekend.

By late Sunday night and Monday morning, another cold front will begin to
move through the basin. The front and associated rainfall will move east of
the basin by Tuesday night. This front will provide some significant rains to
areas northwest of the Ohio Valley as well as over southeastern portions of
the basin. The remainder of next week will likely be drier than normal with
temperatures normal to cooler than normal.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding continues across much of Illinois, Indiana, northwest Ohio,
and western Kentucky. Moderate flooding remains across the lower portions
of the White, East Fork White, Wabash, and Little Wabash. Major flooding is
ongoing on portions of the Patoka River in southern Indiana. The threat of
additional flooding is low this week and into the weekend. Flood potential
may increase again early next week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain generally affected areas north of the Ohio River. Highest basin average
amounts were 0.50 to 0.90 inch in east central Indiana and the northern half
of Ohio.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
The bulk of the rain in the forecast is in the first 24 hours. Highest basin
average amounts will range from 0.25 to 0.40 inch in far eastern Ohio, western
Pennsylvania and much of West Virginia.
