...HYDROMETEOROLOGICAL DISCUSSION...
A weather system will cross the Ohio Valley today. Rain will continue to lift
into the basin from the southwest. Rains will generally be light with this
system. Some precipitation will be in the form of snow in the northwest.

A more significant area of low pressure will lift through the basin from the
southwest on Tuesday. It will provide 1/2 to 1 inch of rain to much of the
basin.

Significantly colder air and more widespread chances of snow are forecast to
move into the basin behind this system late in the week and over the next
weekend.

The threat of flooding is low at this time.

Erie.

much of Kentucky and Tennessee as well as southern Illinois. Basin averages
increased to the south with 0.25 to 0.85 inch in middle Tennessee.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain, and some snow, is forecast across the entire Ohio Valley. Basin average
amounts generally increase to the south. Southern Illinois, southwestern
Indiana, most of Kentucky and Tennessee will see amounts greater than 0.50 inch.
