...HYDROMETEOROLOGICAL DISCUSSION...
A weak disturbance moving through the Ohio Valley today will generate light
rain showers. On Wednesday a more significant low pressure system will cross
the TN Valley. It will draw precipitation into the area, mainly south of the
Ohio River. Moderate to heavy rain is forecast across the southern basin.
Quiet weather is expected for the end of the work week, but another
significant storm system will impact the basin late Friday into Saturday.

...FLOOD POTENTIAL DISCUSSION...
A couple moist weather systems later this week will raise the flood potential,
especially across the southern half of the region.

Light rain/drizzle fell across much of the basin. Amounts were mostly under
0.10".

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light rain is forecast today with amounts on the order of a few hundredths.
Heavier rain is forecast Tuesday across TN and KY, mainly between 0.50" to
1.50" through Weds morning.
