Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1135 AM EST Tuesday, December 1, 2015
A front that had pushed south of the basin yesterday lifted north into the
southern Ohio Valley again. This drew widespread rainfall into the southern
two-thirds of the Ohio Valley. As the front drops south again tonight a low
pressure system will ride through the southeast Ohio Valley, again enhancing
rainfall in that area. Rains will finally move out of the southeastern portion
of the basin on Wednesday.
A low pressure system will pass across the Great Lakes on Wednesday and early
Thursday. This will provide some minor shower activity across the northeastern
half of the Ohio Valley.
High pressure will build into the Ohio Valley later in the week bringing an
end to the wet conditions. The next significant precipitation in the Ohio
Valley isn`t expected until early to mid next week.
...FLOOD POTENTIAL DISCUSSION...
Minor flooding continues in the Little Wabash Watershed of southern Illinois.
The flood potential will increase across the southern basin by mid-week in
response to rainfall in that region. Any flooding that does develop would
be minor in nature.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell over all but the northeastern Ohio Valley. Amounts were highest in
middle Tennessee and Kentucky where basin averages ranged from 0.50 to 1.75
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected everywhere with the exception of the west central Ohio Valley.

and far western Virginia.
