Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1044 AM EST Thursday, December 14, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Low pressure that brought snow to the northern basin overnight is moving
briskly off to the east. High pressure is filling in behind the disturbance
allowing for quiet conditions to return for much of the region. A few weak
systems will cross the Great Lakes the next few days, bringing more light
snow showers to the upper Ohio Valley. Heavier snowfall totals are forecast
in the Lake Erie snow belt. Warmer weather returns this weekend and a minor
rain event is shaping up for Sunday.

...FLOOD POTENTIAL DISCUSSION...
With little liquid precipitation expected for the next week or so, the
flood potential will remain low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow affected the northern half of the basin. Liquid equivalent amounts
were heaviest in northern OH, western NY, and western PA with between
0.25" to 0.50". Lesser amounts fell across northern IN, central OH, and
northern WV. The southern half of the basin remained dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light snow and lake-effect snow is forecast across the northern basin.
Amounts will be modest, except in northeast OH, northwest PA, and western
NY where 0.25" to 0.75" of liquid equivalent is expected.

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