Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1032 AM EDT Tuesday, October 21, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
An upper level low pressure system will gradually drift from the eastern Great
Lakes today to off the mid-Atlantic coast on Wednesday. As a result, showers
and isolated thunderstorms will affect the northeastern half of the basin
today, but only the far eastern portion of the basin on Wednesday before
ending.

High pressure will keep the entire basin dry on Thursday.

A weak disturbance is forecast to pass through the area Friday and Friday night
providing a minimal amount of rain to the region. After this, the weekend and
early next week are expected to be dry.

...FLOOD POTENTIAL DISCUSSION...
The flood potential is low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and widely scattered thunderstorms affected all but the far west
central Ohio Valley. Basin averages were mostly less than 0.50 inch, but
portions of central to northeastern Ohio ranged up to near 1.00 inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is expected in the northeastern half of the Ohio Valley. Basin averages
increase to the east with totals ranging from 0.25 to 0.40 inch in northeast
Ohio, west Pennsylvania and east West Virginia.

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