Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1108 AM EST Tuesday, December 12, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Snow shower activity was scattered throughout the Ohio valley this morning and
will continue in areas downwind of the Great Lakes. Yet another clipper system
will bring another round of light snow later on Wednesday into Thursday morning.
The region will warm over the weekend and some rain will be a possibility on
Sunday.

...FLOOD POTENTIAL DISCUSSION...
River flows are currently at climatological minimums. Little if any liquid
precipitation or snowmelt is expected for the rest of this week, keeping the
potential for any flooding very low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
The northeastern part of the service area along the Lake Erie shore has several
inches of snow yesterday and overnight once again, but most of the basin had
only insignificant amounts of snow.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Lake-effect snow has begun again in the usual snow-prone areas downwind of the
Great Lakes.  Amounts expected through daybreak Thursday are about an inch in
northwest Pennsylvania.  But only a tenth or less is expected elsewhere in the
service area.

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