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
