Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1210 PM EDT Thursday, May 23, 2013

...HYDROMETEOROLOGICAL DISCUSSION...
A cold front crossing the basin will produce more showers and thunderstorms
today. A cooler, drier airmass will settle into the region for Friday and
Saturday. A warm front will gradually spread showers and thunderstorms back
into the western and northern basin beginning Sunday and lasting into mid
next week.

...FLOOD POTENTIAL DISCUSSION...
No flooding is expected in the Ohio Valley for the next few days. Unsettled
weather next week could cause some decent rises in the northern/western
basin. Flooding is not expected at this time, but it can not be ruled out.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers and thunderstorms were widespread across the basin. Most locations
received measurable rainfall; however, basin average amounts were generally
under 0.25". The exception was across the eastern Ohio Valley where amounts
ranged from 0.25" to 1.00".

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
The bulk of the precipitation falls on Day 1. On average, amounts will
remain below 0.25" in most areas, but the eastern third of the basin could
see 0.25" to 0.50". Lingering activity in the far eastern basin Friday morning
could produce another 0.10" or so before ending in the early afternoon.

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

Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1247 PM EDT Wednesday, May 22, 2013

...HYDROMETEOROLOGICAL DISCUSSION...
Showers and thunderstorms will be common in the Ohio Valley through Thursday.
Atmospheric disturbances will propagate along a slowly advancing cold front
which was just entering the western edge of the Ohio Valley at midday Wednesday.

...FLOOD POTENTIAL DISCUSSION...
New flooding is not expected from the rainfall in the Ohio Valley this week,
although rivers in the western basin will see some significant rises.  The
heaviest rains should be isolated and infrequent enough not to produce river
flooding, although small stream flooding and urban flooding is still very
possible.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Thunderstorm activity was widespread in the southern half of the basin yesterday
where 1 inch or more of rain was common in some regions.  Scattered showers and
thunderstorms were also observed in the northern part of the area.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Over an inch of rain is forecast over parts of West Virginia through Friday
morning, but most of this activity will occur overnight tonight.  The remainder
of the basin will see the threat of rain diminish gradually from west to east.

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