Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1158 AM EDT Friday, August 22, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
Unsettled weather will continue today into the weekend with a moist airmass
parked over the Ohio Valley. The threat for heavy rain will remain for
parts of the western basin. As the weekend unfolds, high pressure will
gradually strengthen. As a result, conditions will not become dry, but storm
activity will be more limited.

A ridge of high pressure will be situated over the basin into early next
week, providing above normal temperatures and scattered shower and
thunderstorm activity.

...FLOOD POTENTIAL DISCUSSION...
River flooding is occurring/expected in Indiana where parts of the state
received 5-10" of rain. Elsewhere, the potential for additional river
flooding is generally low, although with more storms expected in the near
future, it can not be ruled out. Flash flooding may occur in areas that see
locally heavy rainfall.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain fell across all of the Ohio Valley except the southwest portion.
Amounts were very heavy in northern IL, northern/central IN, and western OH.
Parts of east-central IN received 5" to 10".

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms are forecast across much of the basin. The
heaviest axis will be similar to the previous 24 hrs, extending across IL,
IN, southern/western OH, northeast KY, and southern/central WV. Generally
between 0.50" go 1.50" is forecast here, although locally heavier amounts
are possible. The southwest, north-central, and northeast basin should see
amounts under 0.25"

...RIVER BASINS IN FLOOD...
None at this time.
