Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1127 AM EDT Monday, July 27, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
A weak disturbance is crossing the region today producing some scattered
showers and thunderstorms in the central and southern Ohio Valley. A ridge
of high pressure will strengthen through midweek with hot and humid
conditions. A few showers/storms will remain possible mainly across the
southeast during the afternoon and evening hours. On Wednesday night and
Thursday, a passing cold front will produce more widespread thunderstorm
activity. Drier air will fill in behind that front however, bringing a quiet
end to the work week.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding lingers in the western basin and will continue to do so for
the next few days. Otherwise, the potential for additional flooding will be
low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Organized, heavy showers and storms fell in central Indiana with 1" to 4".
Less organized activity affected eastern IL, TN, KY, OH, and western PA.
There were some locally heavy pockets of precipitation, but amounts were
generally under 1" in these areas.  Parts of WV and western VA saw some
action as well, but amounts were a half inch or less.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms will be scattered across the region. Amounts
should be minimal across the north, with the heavier totals expected in the
middle and southern tiers. Less than 1" will fall in most places although
locally heavier amounts are likely in thunderstorms.
