Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
956 AM EST Friday, February 27, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
Strengthening high pressure will gradually bring an end to snow shower
activity later today. Cold and dry conditions will remain through Saturday.
Beginning Saturday night into Sunday, warmer air will begin to lift
northward. Widespead rain and rising temperatures are forecast along and
south of the Ohio River into early Monday. Meanwhile, snow is expected across
the northern basin.

There will be a brief respite late Monday, but another strong weather system
is forecast to move through the area Tuesday and Wednesday. This disturbance
is expected to be even warmer and wetter than the first. Together, these two
systems are expected to produce significant snowmelt, especially in the
middle and southern portions of the basin.  Flooding is expected.

...FLOOD POTENTIAL DISCUSSION...
The threat of flooding is low through the end of this month. The flood risk
will rise significantly next week with warmer and wetter conditions forecast,
particularly with the second system midweek. Flooding could reach moderate to
major levels in spots.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light snow showers were scattered throughout the basin. Basin-average
amounts were around 0.05" (liquid-equivalent) or less.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light rain/snow is forecast to lift into the western basin late in the
forecast period. Forecast amounts are 0.25" or less for Saturday night.
Until then, dry conditions will be the rule.

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