Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1159 AM EDT Monday, August 22, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
High pressure is in control across the basin with a cooler and drier
airmass in place. As a result quiet conditions are forecast the first half
of the week.

The next chance of rain will be late in the week as moisture returns and a
disturbance works through the region. Showers and thunderstorms will develop
and gradually spread from west to east across the basin late Wednesday thru
Thursday.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding continues in the Little Wabash Watershed of southeast
Illinois.  River levels are also elevated across parts of southern Indiana
and western Kentucky, though these areas will remain below flood stage.  The
threat of new flooding is low the next few days, but may increase somewhat
as humidity returns and the next storm system rolls through later this week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms impacted northeast OH, western NY, western PA,
WV, southern and eastern KY, and Middle TN. Amounts ranged from a few
hundredths up to around a half inch with locally heaver amounts up to
three-quarters of an inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
A few hundredths are forecast in the northeast Ohio Valley - to the lee of
Lake Erie, and also in the northwest basin late in the forecast window.
Otherwise, the basin will be overwhelmingly dry for the 48-hr period.

...RIVER BASINS IN FLOOD...
