Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1040 AM EDT Sunday, October 22, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
An approaching cold front will generate showers across the western Ohio
Valley today. Strong low pressure will lift northeast along the front and
across the region Monday, producing more widespread and heavier rain along
with embedded thunderstorms. The low exits the basin Tuesday and a much
cooler airmass will settle into the area behind it. Scattered showers will
linger into midweek as an upper trough digs into the eastern US.

...FLOOD POTENTIAL DISCUSSION...
The threat of flooding will increase early this week as low pressure brings
with it the chance for excessive rainfall. Flooding is currently not in the
forecast due to dry soils and only 1" to 2" of rain expected.  However, if
actual rainfall amounts approach 3", minor flooding is certainly possible.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
None.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Widespread rain is forecast. Most of the southern and western Ohio Valley
will see 1" to 2", except locally higher amounts are possible in the upper
reaches of the New River basin in NC/VA.  Meanwhile, central and eastern
Ohio Valley locales can expect anywhere from 0.50" to 1.50".

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