Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1258 PM EST Tuesday, February 9, 2010
...HYDROMETEOROLOGICAL DISCUSSION...
Another vigorous winter weather system was moving through the Ohio Valley on
Tuesday. Precipitation with this system initially started as snow in the
southern Ohio Valley, but later changed to rain. North of the Ohio River,
precipitation has been almost entirely snow. Some rain will continue in areas
such as eastern Kentucky and West Virginia before changing over to snow later
tonight. While the heaviest precipitation should be moving through the region
during the day today, light persistent snow will continue into the day
Wednesday before coming to an end from west to east.
The longer range outlook for the next two weeks indicate a continuation of
the cold temperatures and occasional snows. Only insignificant snow melt is
expected during this period.
...FLOOD POTENTIAL DISCUSSION...
Some isolated minor flooding was ending today across parts of the Green
Watershed. Otherwise, the potential for additional flooding is low through
this week.
...24-HR OBSERVED PRECIPITATION USED FOR TODAY'S RIVER FORECASTS...
Measurable precipitation fell across all of the Ohio Valley except the
northeast. Heaviest basin average amounts fell in middle Tennessee. Amounts
ranged from 0.50 to 1.20 inch in this area.
...24-HOUR FORECAST PRECIPITATION USED FOR TODAY'S RIVER FORECASTS...
Precipitation is forecast basin-wide. Basin-average liquid-equivalent 24-hour
amounts will be highest in northern Ohio, southwest Pennsylvania and much
of West Virginia where they will range from 0.50 to 0.60.
