Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
117 PM EST Wednesday, December 7, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
Lake-effect heavy snow, rain and frigid temperatures are all in store for the
Ohio Valley in the next week.  Cold air moving into the region on Thursday will
kick off persistent snow lee of Lake Erie, giving many inches of snowfall there
before it comes to an end on Sunday.  Another weather system will bring rain and
snow to the area early next week, then frigid air will begin to push into the
basin around midweek, after which high temperatures will remain below freezing
for a few days over most of the region.

...FLOOD POTENTIAL DISCUSSION...
The threat of flooding is low through the weekend.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rainfall reports exceeding an inch were common in the Appalachians yesterday and
overnight.  Most of the basin had a quarter to half inch, with a tenth of less
in the extreme northwest basin.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Over of half inch of liquid-equivalent precipitation is forecast in the
northeastern basin for Day 2.  All of this will be in the form of snow.

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