Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1119 AM EDT Tuesday, September 2, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
A cold front will advance through the Ohio Valley today sparking showers and
thunderstorms until high pressure builds in behind the front tonight.
Generally quiet conditions are forecast on Wednesday/Thursday with a drier
airmass in place. By Friday, southerly flow will draw moisture back into
the region - and a cold front will help generate more unsettled weather into
the first half of the weekend.

...FLOOD POTENTIAL DISCUSSION...
Heavy rains that recently fell over the western Ohio Valley could cause
some minor river flooding in the Little Wabash watershed.  Otherwise, the
potential for river flooding is low.  The potential remains for flash
flooding later today and again late this week and early weekend due to
locally heavy rains in thunderstorms.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Heavy rain of 1" - 4" was observed across eastern IL, central and southern
IN, and southwest OH. Elsewhere, rainfall amounts were widespread but
generally on the light side with basin averages around 0.25" or less.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms will be scattered throughout much of the region.
Forecast amounts generally call for 0.10" to about 0.50" with locally
heavier amounts to 0.75" extending up along the Ohio River in the middle of
the basin.

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