Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
140 PM EDT Friday, March 27, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
An upper level trough will cross the Ohio Valley tonight bringing colder than
normal air to the basin. Though rain and snow showers are expected over much of
the basin during the remainder of today, most areas will not receive enough to
measure.

High pressure over the area Saturday and early Sunday will keep the area dry.

A quick moving cold front will push through the basin late Sunday to early
Monday bringing light showers, mostly in the form of rain, to much
of the basin.

The next chance for any significant rain appears to be late next week, but it
is too early to tell whether any rainfall will be excessive.

...FLOOD POTENTIAL DISCUSSION...
Flooding continues in the lower Ohio Valley. The potential for any additional
flooding is low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Nearly all of the Ohio Valley saw rainfall. Basin averages were heaviest,
ranging from 0.50 to 0.90 inch, in eastern Kentucky and southern West Virginia.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Very light amounts of precipitation, with liquid-equivalent amounts less than
0.10 inch, will be scattered across much of the Ohio Valley, with most coverage
in the northeast.
