...HYDROMETEOROLOGICAL DISCUSSION...
Much of the region remains in the warm sector of an approaching disturbance
with mild temperatures and generally quiet conditions for now. As the cold
front encroaches into the Ohio Valley later today and overnight, showers
and thunderstorms will develop and push across the region, lasting into
Sunday. Rain will be widespread and amounts will mostly range from 0.50" to
1.00" basin-wide.

Another low pressure system is forecast to move through the basin around
Monday night/Tuesday. It will be weaker, but still should provide another
dose of rainfall to the basin, especially the southern half.  Wednesday and
Thursday will be generally quiet again and continued mild, but another
frontal system arrives by the end of the work week.

...FLOOD POTENTIAL DISCUSSION...
With several rain events lined up to affect the basin the next 7 days, the
potential for minor flooding will rise this upcoming week...especially in
the western portion of the Ohio Valley.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light showers fell across the western, northern, and eastern peripheries.
Amounts were mostly under 0.10".  A large majority of the basin was dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms will develop this weekend. Widespread amounts of
0.50" to 1.00" are forecast with locally heavier amounts in thunderstorms.
