Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
107 PM EST Saturday, February 13, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
Some Lake Effect snow showers from both Lakes Michigan and Erie will affect the
northern and eastern portions of the Ohio Valley today, though they will be
light. This activity should taper off from west to east later today as high
pressure moves across the basin.

A warm front will lift into the basin Sunday and Sunday night. This will bring
a mix of weather with snow in the north and a mix in the south.

Another stronger system will move across the southeastern Ohio Valley late
Monday into Tuesday. There is still some question as to where this low pressure
system will track, which can change which areas may get the heaviest rainfall
and where a rain/snow line will set up. It will be a complex system, but it
appears the heaviest liquid precipitation will be across the southeastern Ohio
Valley.

Another weaker disturbance will pass across the southern Ohio Valley on Tuesday
and Tuesday night continuing the chances of rain and snow.

Temperatures are expected to moderate to near or above normal by the end of
the week.

...FLOOD POTENTIAL DISCUSSION...
Frigid temperatures this weekend will give way to more normal temperatures next
week. Additionally, a series of disturbances will provide some liquid
precipitation, mainly in the south. This will result in some river rises, but
the potential for flooding remains low through the upcoming week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Snow showers affected most of the Ohio Valley. Basin average liquid-equivalent
amounts were ranged from 0.10 to 0.25 inches only in northeastern Ohio, far
western New York, portions of western Pennsylvania, southern West Virginia,
southeastern Kentucky and far western Virginia.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Precipitation is forecast across the entire Ohio Valley. Basin averaged liquid-
equivalent amounts will increase to the south with 0.25 to 0.75 inch forecast
across southern Kentucky, middle Tennessee and far southern West Virginia.

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

Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1017 AM EST Friday, February 12, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
A weak disturbance moving through the southern Ohio Valley today will result of
some light accumulations of snow.

Lake effect and terrain enhanced snow showers will also persist today and
Saturday in the northern and eastern Ohio Valley, though they will gradually
recede to the northeast. The coldest air will settle into the Ohio Valley on
Sunday as arctic high pressure moves across the area.

As the day proceeds Sunday, moisture from an approaching low pressure system
will begin to work its way into the western Ohio Valley. By Monday low pressure
will move across the southeastern Ohio Valley. There is some potential for a
rain event across that area Monday into Tuesday, but there is low confidence
in exactly where the storm will track. Thus it is difficult at this time to
forecast exactly how much and where rain will fall and where a rain/snow line
will set up.

Temperatures are expected to moderate to near normal by the end of next week.

...FLOOD POTENTIAL DISCUSSION...
Frigid temperatures and a lack of rainfall will keep the flood potential
very low in the Ohio Valley.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Scattered snow showers produced light amounts across parts of southern
Illinois, western Kentucky, middle Tennessee, northeastern Ohio, northwestern
Pennsylvania and far western New York.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light snow showers are forecast across most of the basin with liquid-equivalent
totals 0.10 inch or less. Only in the immediate vicinity of Lake Erie in
Pennsylvania and far western New York will we see totals in the 0.25 to 0.35
inch range.

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

Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
828 AM EST Thursday, February 11, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
Arctic high pressure is providing generally quiet and cold conditions today
with only a few flurries or light snow showers.  A weak clipper diving into
the region Friday will spark some more snow shower activity, though
accumulations will be light. Another blast of cold air will arrive over the
weekend.

...FLOOD POTENTIAL DISCUSSION...
Frigid temperatures and a lack of rainfall will keep the flood potential
very low in the Ohio Valley.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Scattered snow showers produced light amounts across parts of the region.
Heavier totals fell in the Lake Erie snowbelt with between 0.10" to 0.50"
of liquid equivalent.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light snow showers will affect much of the basin. Amounts will generally
be less than 0.10" except 0.10" to 0.50" in the Appalachians and Lake Erie
snowbelt.

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