Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1146 AM EDT Monday, April 24, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Low pressure over Alabama Monday morning will continue to track eastward and
then lift up the mid-Atlantic coast Tuesday. Moisture wrapping around this low
will continue to affect the eastern Ohio Valley through Tuesday.

After a break in the weather, a cold front will push through the Ohio Valley
Thursday morning and afternoon. While rainfall amounts may be somewhat
significant along the western edge of the Ohio Valley, the front will weaken as
it moves east through the area, so most areas will see only modest amounts
of precipitation.

Southerly flow will continue to keep temperatures above normal over the
upcoming weekend. Unstable conditions will promote showers and storms across
the basin over the weekend with another cold front forecast to pass through
around next Monday.

...FLOOD POTENTIAL DISCUSSION...
Significant rainfall totals over the past 3 days in middle Tennessee, southern
Kentucky and far western Virginia have resulted in some minor flooding in
portions of southeastern Kentucky and far western Virginia. Some isolated,
short-lived, moderate flooding is also possible on the upper Cumberland River
in southeastern Kentucky. While there will be many significant river rises
elsewhere, additional flooding is not expected.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell south of the Ohio River with increasing amounts to the southeast.
Portions of eastern Tennessee, southeastern Kentucky and far western Virginia
received 1.25 to nearly 4.00 inches of rainfall.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast for far western New York, western Pennsylvania, West Virginia
and far western Virginia. Basin average amounts along the far eastern edge of
the forecast area will be 0.50 to nearly 1.00 inch, but most areas will see
light amounts.

...RIVER BASINS IN FLOOD...
Points along the following river basins were in flood Monday morning:
