Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
100 PM EDT Friday, September 4, 2015
A cold pool of air aloft will be enough instability to allow showers and
thunderstorms to develop in the Ohio Valley this afternoon. While most areas
are at risk for this activity, we expect most storms to be in the northern
portion of the basin closest to this pocket of cool air. This hot and humid
pattern with scattered thunderstorms will likely continue until midweek, when a
change to cooler and drier air is expected by the end of next week.
...FLOOD POTENTIAL DISCUSSION...
The flood potential is low.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rainfall was between 1 and 2 inches in much of the eastern half of Ohio and
parts of Pennsylvania and West Virginia. Most of the remaining basin had none.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rainfall is forecast, mainly under 0.25 inches, again today and tomorrow, in the
northern parts of the basin, with lesser amounts averaging in the southern half
of the basin.
