Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1147 AM EDT Friday, May 29, 2015
Moisture will continue to increase over Ohio Valley, so scattered showers and
storms will be possible in most areas today.
On Friday night and into the weekend a slow moving cold front will begin to
push into the basin from the west. It`s slow progression will increase the
potential for excessive rainfall in any given area. The potential for heavy
rain appears to be higher to the south of the Ohio River.
...FLOOD POTENTIAL DISCUSSION...
Today, the potential for river flooding will remain low. Rains over the weekend
may be heavy. There is some potential for minor flooding in the rivers of the
northwest Ohio Valley...specifically in Indiana where it will take less
rainfall to produce minor flooding. Overall, localized flash flooding is more
likely than any river flooding.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rains were mostly scattered across the southern, middle and southeastern
portions of the basin. Basin averaged precipitation amounts were generally 0.40
inch or less.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rains will be widespread and somewhat significant over the next two days. Basin
averages will range from 0.90 to 1.25 inches over the entire northwestern 2/3
of the Ohio Valley. Amounts then taper off to the southeast, reaching around
0.30 inch over far western Virginia.
