...HYDROMETEOROLOGICAL DISCUSSION...
A building ridge of high pressure will moderate temperatures Friday through
Monday. A warm front arriving this weekend will generate some very light rain,
but it is not until Monday when the trailing cold front will arrive and more
significant rainfall is expected. Even so, amounts are not expected to be
excessive.

Behind the frontal passage Monday, temperatures will remain near normal and
conditions will generally be dry. Another frontal system is forecast to push
through the basin around next Friday/Saturday. This system has the potential to
feature heavier rainfall amounts.

...FLOOD POTENTIAL DISCUSSION...
Local flooding caused by ice jams remains is a possibility -- particularly in
the northern half of the service area. Warmer temperatures over the Ohio Valley
will result in some gradual snow melt. This in combination with rain expected
early next week will produce some significant river rises. There will be an
increasing potential for minor flooding, especially in Indiana, early next
week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
None.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Very light rainfall is forecast over eastern Illinois, Indiana, most of Ohio,
northern Kentucky and West Virginia. Basin average amounts will be 0.05 inch or
less.

...RIVER BASINS IN FLOOD...
None.
