Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1013 AM EST Monday, January 23, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Low pressure over South Carolina at sunrise Monday will lift northeast along
the Atlantic coast. Moisture wrapping around the low will affect the basin
today, but begin to lift northeast out of the area tonight and Tuesday.

Warmer than normal temperatures will remain over the basin until Wednesday when
a cold front pushes through the region. Behind the front northwest flow will
prevail. Occasional disturbances in this flow will provide opportunities for
snow showers or some rain showers in the south. The first disturbance will drop
through the basin on Thursday.

This pattern change will bring cooler and drier conditions for at least the
next couple of weeks.

..FLOOD POTENTIAL DISCUSSION...
Minor flooding will continue on many of the western rivers in the Ohio Valley.
Rainfall today will allow rivers to rise again, increasing the potential for
some additional minor flooding in portions of northern Ohio.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain was scattered over much of the Ohio Valley, though there was very little
over the northwest quadrant. Basin average amounts generally increased to the
southeast. Amounts greater than 0.50 inch fell over portions of middle
Tennessee, southeastern Kentucky, southern West Virginia and far western
Virginia. In fact, far western Virginia saw basin averages in the 1.00 to 1.75
inch range.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast over all but the southwestern Ohio Valley. Basin averages
will range from 0.50 to 1.25 inches in portions of far western New York,
western Pennsylvania all of West Virginia, eastern Kentucky and far western
Virginia.
