Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1109 AM EST Saturday, February 25, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
An upper disturbance behind the cold front will spark some rain/snow
showers in the basin today.  High pressure will gradually build into the
region tonight leading to dry conditions Sunday. The weather pattern
will become unsettled again Monday as a series of waves begin to traverse the
Ohio Valley. The first couple disturbances will be relatively weak, but a
stronger wave of low pressure arriving around midweek could produce heavy
rain in the basin.

...FLOOD POTENTIAL DISCUSSION...
The threat of flooding will be minimal until the middle of next week when a
moist disturbance could produce heavy rainfall.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Scattered showers and thunderstorms produced highly variable amounts ranging
from a few hundredths in spots up to around an inch in the heavier
thunderstorms.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
A cold front moving through the eastern basin will generate rainfall on the
order of 0.25" or so. Behind the front, scattered rain/snow showers in the
middle of the basin could produce a few hundredths. Rainfall arriving in
the lower Ohio Valley Monday morning is forecast to produce 0.10".

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