Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1201 PM EDT Friday, May 24, 2013

...HYDROMETEOROLOGICAL DISCUSSION...
A cooler, drier airmass will settle into the region today bringing an end
to showers in the eastern basin and allowing skies to gradually clear.
A warm front will nose into the Ohio Valley this weekend, opening the
door for showers and thunderstorms in the western basin. This activity will
spread eastward through the rest of the basin Monday and Tuesday. A strong
ridge of high pressure will then develop by midweek. Hot and humid conditions
will take over with little in the way of precipitation expected through the
end of the work week.

...FLOOD POTENTIAL DISCUSSION...
No flooding is expected in the Ohio Valley through the weekend. Unsettled
weather early next week could cause some decent rises in the
western/northwestern basin. There is a small risk of some minor flooding,
mainly confined to the Wabash.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms were scattered across the region once again.
Activity was concentrated throughout the eastern third of the region,
with basin average amounts ranging from 0.25" to 0.75".  The western
two-thirds experienced more hit-or-miss activity leading to basin average
totals generally around 0.10" or lower.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Some lingering showers in the far east today were forecast to produce
around 0.05" or less before ending in the afternoon.  Showers and storms
expected on Saturday/Saturday night will produce around 0.25" in IL, IN,
western KY.

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