...HYDROMETEOROLOGICAL DISCUSSION...
A cold front will continue to pass from west to east through the Ohio Valley
today. While showers will be scattered ahead of the front, behind it, drier,
cooler weather will take its place with a large and wide upper level trough
to the north.  Some light rain is possible across the middle of the Ohio Valley
on Tuesday, but most of the week will remain dry.

The next chance of significant rain appears to be over the upcoming weekend,
but amounts are not expected to be excessive.

...FLOOD POTENTIAL DISCUSSION...
Flooding continues in portions of Kentucky, southern Indiana, and southern
Illinois. Moderate flooding is confined to two locations on the lower Green
River. Flooding is expected to become more widespread over southern Indiana
over the next several days, but will remain minor in nature.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell across the entire Ohio Valley. Heaviest rains fell from middle
Tennessee, north through western Kentucky and Indiana. Basin averages in this
region ranged from 1 to 2 inches. Additional heavy rains fell in the headwaters
of the New River of far western Virginia where basin averages ranged from 2 to
3.5 inches.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected across most of the basin, but amounts will generally increase
