Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
936 AM EDT Wednesday, April 23, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
The OHRFC basin is dry, save for a few lingering lake-enhanced showers in the
farthest northeast reaches of the basin. The next 24 to 36 hours will remain dry
as high pressure is in control.  Starting late Thursday, a few showers will
begin to make their way into the western fringes of the basin out ahead of the
next cold front.  This cold front will be similar to yesterday`s front (rather
progressive from west to east), but will have a little more moisture associated
with it. It will move through during the overnight on Thursday/Friday and be out
during the later half of the day on Friday.

Next week seems to signal a different outlook than this week.  a cut-off low
pressure system will meander from the central plains to the TN and OH valley
early to midweek.  With a much slower progression, this will mean an unsettled
and wet week.  Details are still highly variable in the models.

...FLOOD POTENTIAL DISCUSSION...
The potential for flooding is low this week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Generally a quarter of an inch or less for the eastern third of the basin.  A
few swaths gave a little more than a half of an inch, but these were few and far
between and very localized.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain moves back into the basin late Thursday into Friday....amounts forecast top
out at six or seven tenths along the western and southwest fringes of the
forecast area.  Totals taper off to around a quarter of an inch by the central
basin.

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