Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
149 PM EDT Tuesday, July 7, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
A cold front will slide into the basin today before stalling around the
Ohio River tonight. Showers and thunderstorms associated with this feature
will affect much of the the Ohio Valley.  A secondary area of low
pressure traversing the front Wednesday night will bring another round of
significant rainfall along with it.  High pressure will gradually ease
into the region Thursday, providing quieter weather through Friday.
However, more unsettled weather is expected over the weekend.

...FLOOD POTENTIAL DISCUSSION...
Minor to moderate flooding continues across the western Ohio Valley from
previous rains.  The potential for any additional river flooding is
somewhat elevated due to 1-3" rain possible this week, but the greater
threat will be urban and flash flooding.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms fell over the eastern Ohio Valley on Monday, and
across far western areas earlier this morning.  Parts of IL and western KY
received several inches of rain.  Meanwhile, a large portion of the central
Ohio Valley was dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms are expected to produce rainfall for almost the
entire Ohio Valley. Heaviest amounts are forecast in IL, IN, OH, KY, and
WV with 1" to 2" expected across a broad area, and locally heavier amounts
possible in thunderstorms.
