Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
959 AM EST Thursday, December 7, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Light snowfall activity will become more common in the Ohio Valley for the next
week at least as significantly colder air settles into the Ohio Valley for a
while.  Any precipitation should be in the form of snow, and so this will have
very little hydrologic impact on the basin.  The exception is along the Lake
Erie shoreline, where well more than a foot of snow is expected over the next
week.  This will have a delayed hydrologic impact when that snow melts later in
the month (if then).

...FLOOD POTENTIAL DISCUSSION...
River flows are currently at climatological minimums. Little if any liquid
precipitation is expected over the next couple of weeks, keeping the potential
for any flooding very low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Some measurable snow fell in southwestern New York just downwind of Lake Erie.
Elsewhere, flurries were observed, but nothing measurable.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
A half inch or more of liquid-equivalent snowfall is forecast east of Cleveland
along the Lake Erie shore.  But most of the service area will see only light
amounts of snow through Saturday morning.

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