Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1000 AM EST Wednesday, December 13, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Another installment of cold air will bring another round of snow to the Ohio
Valley. Most of this will fall in the northern basin, but the cold air will kick
in the lake-effect snow machine downwind of the Great Lakes once again.  Warmer
weather returning over the weekend will set the stage for a possible heavy rain
event early next week.

...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.  The potential for flooding increases next
week, however.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
More snow fell in the service area.  Area in southwestern New York had the most
with about a half inch of liquid-equivalent snowfall.  The mountains of West
Virginia also had over a quarter inch on much of that region.  Elsewhere,
amounts were a tenth of an inch or less.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow is forecast again in the northern half of the service area.  Amounts over a
half inch are again expected downwind of Lake Erie.

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