Ohio River Forecast Center, Wilmington, Ohio
1145 AM EST Monday, December 9, 2013
High pressure building into the region will provide generally dry
conditions today except for some lingering showers in the eastern Ohio
Valley. A couple weak disturbances will move through the basin tonight
generating light precipitation in the central and southern Ohio Valley.
The rest of the week will be relatively quiet and cold as high pressure
dominates. The exception will be to the lee of the lakes where lake effect
snow showers will persist until Friday. Another weather system will bring
widespread precipitation over the weekend.
...FLOOD POTENTIAL DISCUSSION...
High flow conditions currently exist south of the mainstem Ohio. Some minor
flooding has occurred in the upper Cumberland and Kentucky the past few
days, but the potential for additional flooding is minimal with no
significant precipitation forecast this week. The lone exception is on the
lower Ohio River at Newburgh, IN later this week as water routes down.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Locations north of the Ohio River received very light amounts mostly under
0.10". South of the Ohio amounts were more significant with much of eastern
KY, eastern TN, WV, western VA, and northwest NC receiving 0.50" to 1.50".
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
A large part of the Ohio Valley will see liquid equivalent precipitation
less than 0.10". Parts of the southeast Ohio Valley could see over 0.50",
while the Lake Erie Snowbelt is forecast to receive around 0.25" to 0.50".
