Ohio River Basin Hydrometeorological Discussion

1133 AM EST Monday, March 3, 2014
A band of snow that was affecting areas south of the Ohio River on Monday
morning will gradually push to the southeast of the basin. High pressure
building in behind the system will allow temperatures to drop to much colder
than normal levels tonight.
A weak wave will pass to the north of the basin Tuesday, possibly providing
some very light snow across the northern Ohio Valley. Another weak system
will push through the region on Wednesday and Thursday. This also will
provide some precipitation, especially across the north and south portions of
the basin, but it will be scattered in nature with many areas remaining dry.
Temperatures will moderate, becoming more normal toward the end of the week.
The next chance for rainfall resulting in significant runoff will likely not
be until late in the weekend or early next week.
...FLOOD POTENTIAL DISCUSSION...
Minor flooding persists mainly on the lower half of the Wabash River and
on isolated portions of the lower Ohio River. There is still the risk for
ice jam flooding across the far northern basins.
...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Precipitation was widespread. Basin averages increased to the south. Liquid-
equivalent basin average amounts greater than a half inch were generally
restricted to areas along or south of the Ohio River. Some totals across
southern Kentucky and middle Tennessee ranged from 2 to nearly 3 inches.
...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
On day 1 precipitation will fall primarily south of the Ohio River with amounts
increasing to the southeast. Portions of far western Virginia will see totals
near 0.50 inch. On day 2 only very light amounts, less than 0.10 inch, are
expected across far northern Indiana and northwestern Ohio.
