Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
943 AM EST Saturday, December 16, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Lake effect snows that have affected the northeastern Ohio Valley this week are
expected to taper off tonight. Elsewhere, conditions will be today and tonight.

On Sunday a disturbance will push into the basin from the southwest. Warmer
temperatures with this system will bring rain, rather than snow, to the entire
region, but amounts will be light. Some rain will linger into Monday.

On Wednesday a low pressure system is forecast to move through the Dixie
States, but it may pull moisture into areas south of the Ohio River.

Thursday and Friday a system moving through the northern Ohio Valley will
provide more light precipitation in that area.

...FLOOD POTENTIAL DISCUSSION...
Upcoming warming trend will be gradual enough for any snowpack present
to slowly melt. And despite the light rain anticipated on Sunday, flood
potential will remain low with only minor rises on area rivers.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow showers affected northeastern Ohio, western Pennsylvania and far western
New York. Basin average liquid-equivalent amounts were generally 0.10 inch or
less, but some totals in far western New York were around 0.50 inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Precipitation is forecast across the entire Ohio Valley. Most areas will see
totals of 0.10 inch or less.

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