Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1206 PM EST Thursday, January 15, 2009

...HYDROMETEOROLOGICAL DISCUSSION...
Although light snow shower activity will linger in the usual snow-prone areas
of the Ohio Valley through tonight, the basin has basically dried out and will
remain that way into Saturday as Arctic air settles into the basin.  A warm
front will trigger some more snow across the northern basin on Saturday and
another clipper will bring more light snow over most of the basin on Sunday,
then again about Tuesday.

...FLOOD POTENTIAL DISCUSSION...
With cold temperatures and a lack of liquid precipitation in the forecast, the
flood potential will remain low for another week.

...24-HR OBSERVED PRECIPITATION USED FOR TODAY`S RIVER FORECASTS...
Light snow fell across most of the Ohio Valley yesterday, except in the
southern basin.  Liquid-equivalent basin-average amounts were generally a
quarter inch or less.

...24-HR FORECAST PRECIPITATION USED FOR TODAY`S RIVER FORECASTS...
Light snow of flurries are expected in the northeast half of the basin today
and in the northeast quarter of the basin tonight.

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

...HYDROMETEOROLOGICAL DISCUSSION...
Another is a series of clippers has brought more snow to the Ohio Valley
today. This activity will diminish in the basin overnight.  More snow is
possible over the weekend, especially north of the Ohio River.  No widespread
rainfall is expected in the area for at least the next 7 days, but temperatures
will begin to warm again by the end of next week.

...FLOOD POTENTIAL DISCUSSION...
With cold temperatures and a lack of liquid precipitation in the
forecast, the flood potential will remain low for another week.

...24-HR OBSERVED PRECIPITATION USED FOR TODAY`S RIVER FORECASTS...
Light rain and snow fell across the eastern half of the Ohio Valley early
yesterday, and a new round of light snow has pushed into the Ohio Valley from
the west today.  Liquid-equivalent basin-average amounts were generally a
quarter inch or less.

...24-HR FORECAST PRECIPITATION USED FOR TODAY`S RIVER FORECASTS...
Measurable but light snow is forecast across all but the southwest Ohio Valley.
Liquid equivalent amounts around 0.25 inches are possible in parts of Ohio with
lighter amounts expected elsewhere.

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

Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
136 PM EST Tuesday, January 13, 2009

...HYDROMETEOROLOGICAL DISCUSSION...
Early Tuesday morning a cold front worked its way into the western
Ohio Valley. Ahead of this front a band of snow (in the north) and
rain (in the south) was pushing through the basin, but producing only
very light amounts. This will continue and will exit to the east of
the Ohio Valley later today, but snow showers will linger behind it.

Yet another clipper will bring snow back to the region Wednesday, though
much of the activity will be confined north of the Ohio River.

Arctic high pressure will settle over the region to round out the week.
The frigid airmass may produce the coldest temperatures we have seen all
season.

...FLOOD POTENTIAL DISCUSSION...
With cold temperatures and a lack of liquid precipitation in the
forecast, the flood potential will remain low this week.

...24-HR OBSERVED PRECIPITATION USED FOR TODAY`S RIVER FORECASTS...
Measurable precipitation fell across the western half of the Ohio Valley.
Liquid-equivalent basin-average amounts were relatively light at 0.10
inch or less.

...24-HR FORECAST PRECIPITATION USED FOR TODAY`S RIVER FORECASTS...
Measurable precipitation is forecast across all but the southwest Ohio Valley.
Liquid equivalent amounts increase to the northeast with the upper Allegheny
Watershed forecast to receive amounts right around 0.25 inches.

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