...HYDROMETEOROLOGICAL DISCUSSION...
High pressure will build into the Ohio Valley today bringing dry
conditions.  A potent system crossing the Southeast US on Friday will
spread some rain and snow across the southern and eastern Ohio Valley
into Saturday morning. Some locations could see 0.50" to 1.00" of rain.
Northwest flow behind the system will open the door for a clipper later in
the weekend. Snow showers will be widespread Sunday and Sunday night.

...FLOOD POTENTIAL DISCUSSION...
The potential for river flooding is low, however, some localized minor
flooding is occurring on the Wabash in western IN due to ice jams.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
A wintry mix generated amounts of 0.25" or less for parts of the northern
and eastern Ohio Valley.
