Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1119 AM EDT Tuesday, September 2, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
A cold front will advance through the Ohio Valley today sparking showers and
thunderstorms until high pressure builds in behind the front tonight.
Generally quiet conditions are forecast on Wednesday/Thursday with a drier
airmass in place. By Friday, southerly flow will draw moisture back into
the region - and a cold front will help generate more unsettled weather into
the first half of the weekend.

...FLOOD POTENTIAL DISCUSSION...
Heavy rains that recently fell over the western Ohio Valley could cause
some minor river flooding in the Little Wabash watershed.  Otherwise, the
potential for river flooding is low.  The potential remains for flash
flooding later today and again late this week and early weekend due to
locally heavy rains in thunderstorms.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Heavy rain of 1" - 4" was observed across eastern IL, central and southern
IN, and southwest OH. Elsewhere, rainfall amounts were widespread but
generally on the light side with basin averages around 0.25" or less.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms will be scattered throughout much of the region.
Forecast amounts generally call for 0.10" to about 0.50" with locally
heavier amounts to 0.75" extending up along the Ohio River in the middle of
the basin.

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

Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1152 AM EDT Monday, September 1, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
Humid and warm southerly flow continues to bring occasional bouts of showers to
assorted areas of the Ohio River valley.  These will continue through the course
of the day today and into the overnight hours.  Tuesday will see a cold front
pass through the basin bringing widespread showers and thunderstorms as it
traverses the area.  Behind that, cooler and drier high pressure will take its
place for a day or two before humid air returns to the basin late in the week
and into the weekend.

...FLOOD POTENTIAL DISCUSSION...
Flood potential is currently low. Chances for localized flooding/flash
flooding will increase with the widespread showers and thunderstorms with the
passage of the cold front on Tuesday.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Many areas of the Ohio River forecast basin saw some precipitation over the past
24 hours, though the majority was on the light, a quarter of an inch or less,
side.  There were a few very small, yet concentrated cores of showers that
yielded multiple inches.  There was a 4 to 5 inch core in Greene county of Ohio.
Also, there was a two to three inch core in eastern KY as well as a 2 inch core
in SW New York.  Again, all very small and localized.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Widespread precipitation is forecast for the next 48 hours.  Heaviest
basin-average amounts total just over an inch in Indiana, eastern IL, and
northwest OH.  Most other areas measure a quarter to a half inch basin-average.

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

Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1025 AM EDT Sunday, August 31, 2014

...HYDROMETEOROLOGICAL DISCUSSION...
Deep gulf moisture will be drawn into the Ohio Valley providing numerous
showers and storms across the region. These will move gradually from west to
east across the basin today.  A frontal boundary will then arrive late Tuesday
This feature will also bring unsettled conditions as it moves through, but high
pressure should sneak into at least the northern half of the basin until late
in week when heat and moisture will begin returning to entire the Ohio Valley.

...FLOOD POTENTIAL DISCUSSION...
Flood potential is currently low. Chances for localized flooding/flash
flooding will increase late this weekend into next week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Widespread rainfall fell across much of the Ohio River forecast basin over the
past 24 hours.  Heaviest amounts were in the southern basin where areas of two+
inches fell through middle TN and southern KY.  Many other areas of the southern
basin received a half inch or greater.  The northern half of the basin saw a few
smallish cores of an inch or so, but were mainly lighter...along the lines of a
few tenths or less.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Widespread precipitation is forecast for the next 48 hours.  Heaviest
basin-average amounts total just over an inch in West Virginia and eastern KY.
Also have moderate totals through middle IN of three-quarters of an inch or
greater.

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