Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1257 PM EDT Friday, April 21, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
On Friday a cold front was working its way through the southeastern Ohio
Valley. Low pressure developing over the south central US will move quickly
along the front toward the Ohio Valley. Rainfall ahead of this system was
already affecting the southwestern Ohio Valley on Friday. When the low pressure
passes through the basin on Saturday, rainfall will be enhanced across the
southern half of the forecast area. In the far southeast, rain will linger even
into Monday.

Much of next week is shaping up to be relatively quiet with moderating
temperatures.

...FLOOD POTENTIAL DISCUSSION...
With significant amounts of rain across the southern basin over the weekend,
there is some potential for minor flooding across the southern Ohio Valley
beginning late Saturday and into early next week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain affected the entire Ohio Valley. South of the Ohio River, amounts were
generally light. In portions of southern Indiana, northern Ohio, western
Pennsylvania, far western New York and northeastern West Virginia basin average
amounts ranged from 0.50 inch to 1.25 inches.

...60-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast generally along and south of a line from Indianapolis to
Columbus, Ohio, to Pittsburgh. Basin average amounts increase to the southeast
with totals in southeastern Kentucky, portions of middle Tennessee, southern
West Virginia and far western Virginia ranging from 2.00 to 3.25 inches.

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