Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
920 AM EST Wednesday, November 19, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
A weak front will pass through the region today and tonight. This will bring a
dose of light snow to much of the northern Ohio Valley. Behind the front will
be a reinforcing shot of cold air and the potential for more heavy lake effect
snows off of Lake Erie.

Conditions will begin to warm up on Saturday. On Sunday much warmer air will be
drawn into the region. The entire region will see rainfall as well, which
should melt all but the deepest snowpack.

...FLOOD POTENTIAL DISCUSSION...
The potential for flooding is low in the short term. A warmer system could
bring a greater threat of flooding early next week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light snow showers fell over the eastern and northern Ohio Valley, but in many
places was too light to measure. Snows off of Lake Erie in western New York
were historically high, but were just barely northeast of the top of the
Allegheny Watershed.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Measurable precipitation is forecast for most of the northeastern half of the
Ohio Valley. Most amounts will be very light. Basin averages will range from
0.25 to 0.85 inch in far northeastern Ohio, far northwestern Pennsylvania and
far western New York.

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