...HYDROMETEOROLOGICAL DISCUSSION...
High pressure remains in control across the basin with a relatively cool
and dry airmass in place. Quiet conditions are forecast today. Moisture
will return to the basin around midweek. Showers and thunderstorms will
develop and gradually spread from west to east across the basin late
Wednesday into Thursday.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding continues at the bottom of the Little Wabash in southeast
Illinois.  River levels are also elevated across parts of southern Indiana
and western Kentucky from previous rains, though these areas will remain
well below flood stage.  The threat of new flooding is low through midweek
but will increase somewhat as unsettled weather returns later in the week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
A few showers fell in northeast OH and western PA early on Monday. Amounts
were under 0.05".  The rest of the basin was dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Primarily dry weather is forecast on Day 1. Showers and thunderstorms will
develop in the western basin late tonight and spread through the rest of
the basin through Thursday morning. Forecast amounts call for 0.10" to
0.75" across the northwest and central basin and generally under 0.10"
across the southern and eastern Ohio Valley.
