Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1051 AM EDT Sunday, September 7, 2008 

...HYDROMETEOROLOGICAL DISCUSSION...
Upper level disturbance is currently bringing light showers over the northern
Indiana and Ohio.  These will push through rather quickly though before giving
way to dry conditions this evening and overnight tonight.  Most of the Ohio
River forecast basin will remain dry through the next 24 to 48 hours.  Next
widespread chance of precipitation will occur when a system moves in from the
west on Tuesday.

Beyond that, the middle of the week looks dry with high pressure firmly in
place.  A front will impact the basin late Friday and obviously the tropics will
have to be watched closely to see where Ike makes landfall and if this would
eventually impact the basin.

...FLOOD POTENTIAL DISCUSSION...
Low flood potential at this time.

...24-HR OBSERVED PRECIPITATION USED FOR TODAY'S RIVER FORECASTS...
Light scattered showers fell across the far eastern basin as well as the
northwest quarter of the Ohio River forecast basin.  Amounts were generally
light, on the the order of a couple of tenths or less.

...24-HR FORECAST PRECIPITATION USED FOR TODAY'S RIVER FORECASTS...
Light showers are forecast for northern Indiana and Ohio, with amounts
maximizing at just a couple of tenths.  The southern two-thirds of the basin
should remain dry through the next 24 to 48 hours.

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