Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
119 PM EDT Saturday, July 25, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
High pressure building into the Ohio Valley will keep things dry in the Ohio
River forecast basin for the next 24 hours.  On Sunday, a weak cold front
will approach and enter the area from the northwest.  This front, however, will
not have ample moisture associated with it and should only bring areas of
light, scattered showers into the region.  After this front, the beginning of
the week will see more ridging building back into the midwest and hot and humid
air.  Monday night into Tuesday carries some chance of a convective system swath
through the western basin.  The ridge soon will strengthen more and keep the
basin dry through the second half of next week.

...FLOOD POTENTIAL DISCUSSION...
Flood potential will remain elevated due to existing flooding. New flooding is
not likely for the foreseeable future.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Only a few hundredths of an inch in the far northeast corner of the basin.
Otherwise, zero basin-wide.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Have some widespread light showers forecast for the 12z Saturday to the 12z
Monday period, primarily for the northern half of the basin.  Amounts generally
run from a tenth or two to about a half inch in western IN and eastern IL.
