Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
123 PM EST Sunday, November 8, 2009 

...HYDROMETEOROLOGICAL DISCUSSION...
A high pressure ridge remains anchored over the basin resulting in dry and 
mild conditions. The ridge will begin to break down Monday, but dry
conditions will continue through the day. 

A couple of weather systems will swing across basin beginning Monday night
and lasting through midweek. The most notable disturbance will be the
remnants of Ida, which could bring heavy rain to the southeast Ohio Valley
Tuesday. At the same time, a front dropping in from the northwest will
likely bring some light rain to the northern basin. By the end of the week,
a large area of high pressure is expected to return to the region.

...FLOOD POTENTIAL DISCUSSION...
The potential for flooding is low. Rainfall amounts associated with Ida
remnants are not expected to be substantial enough to cause flooding. 

...24-HR OBSERVED PRECIPITATION USED FOR TODAY'S RIVER FORECASTS...
Zero.

...24-HOUR FORECAST PRECIPITATION USED FOR TODAY'S RIVER FORECASTS...
Zero.

...RIVER BASINS IN FLOOD...
