...HYDROMETEOROLOGICAL DISCUSSION...
Scattered flurries are forecast today as an upper trough of low pressure
pushes through. Beyond this, weather will be relatively quiet the rest of
the work week with gradually moderating temperatures. A warm front will lift
into the basin over the weekend providing light rain, while the trailing cold
front will bring more rain around Monday of next week. At this time, rainfall
amounts are not expected to be very significant.

...FLOOD POTENTIAL DISCUSSION...
The potential for new flooding is low this week with no liquid
precipitation or significant melt expected. However, local flooding caused
by ice jams is a possibility -- particularly in the northern half of the
service area.  The flood potential will increase somewhat early next week as
warmer/wetter conditions move in.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow fell across the southeast Ohio Valley. Most locations saw 2-4" of new
snowfall with liquid equivalent values from a few hundredths up to around
a third of an inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Much of the flurry activity today will not produce measurable
precipitation. However, snow in the far southeast basin could produce a few
hundredths before ending later today.  Day 2 of the forecast should be dry.

...RIVER BASINS IN FLOOD...
None.
