Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1032 AM EST Thursday, December 11, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
Moisture pinwheeling around low pressure in New England will back into the
northeast basin, being enhanced by Lake Erie to produce some significant
snows in western NY and northwest PA, and to a lesser extend northeast OH.
Up to a foot of snow will be possible in these areas. Elsewhere, high
pressure will keep the basin dry this week and through the weekend.  Lake
enhanced snows in the northeast will taper off Friday.  The next
disturbance will hold off until early next week.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding continues along the White and Little Wabash rivers in
southwest Indiana and southeastern Illinois, respectively. Elsewhere, no
flooding is expected as a quiet weather pattern prevails

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light snow affected the eastern third of the basin.  A few inches or less
fell, which produced liquid equivalent amounts under 0.25".  The bulk
of the region was dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow is forecast in the northeast Ohio Valley.  Liquid equivalent amounts
over 1" are forecast in far western NY and northwest PA. Around 0.25" or
less is expected in northeast OH and the remainder of western PA.
Elsewhere, dry conditions are expected under building high pressure.
