Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1140 AM EDT Sunday, July 26, 2015
Currently, a weak cold front will approach and enter the area from the
northwest. This front, however, does not have a whole lot of widespread
moisture associated with it. Heaviest potential rain is in the far western
portions of the region where a few convective systems may be able to make their
way into Illinois and western Indiana. After this front, the beginning of
the week will see more ridging building back into the midwest and hot and humid
air. Next chance of widespread showers could occur with a another "cold" front
moving through on Thursday.
...FLOOD POTENTIAL DISCUSSION...
Some flooding is still occurring in the western basin, but nearly all locations
are receding. New additional flooding is not likely for the foreseeable future.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Mainly zero for the bulk of the Ohio River forecast basin. A few small,
isolated cells were able to get into the northwest basin Sunday evening. A
small locally heavy amount of over an inch was observed in eastern Indiana,
but most of these isolated areas saw only light to moderate amounts.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Have some widespread light showers forecast for the 12z Sunday to the 12z

western basin, in eastern Illinois and western Indiana upwards of an inch is
forecast from being on the eastern extent of a convective system or two from the
