Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
100 PM EDT Monday, March 30, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
A cold front will exit to the east of the Ohio Valley today. Only a few light
showers will affect the eastern portion of the basin before tapering off.

A weak disturbance will move through the northeastern portion of the basin
tonight and Tuesday resulting in some light precipitation there.

Elsewhere, conditions will be dry until Thursday when a more significant cold
front will approach the basin from the northwest. Moisture ahead of the front
will begin to affect widespread areas, but the heaviest rains will be along and
just ahead of the front. This front will slow as it reaches the middle and
southern portions of the basin, resulting in heavier rainfall there. Some
amounts will approach or exceed two inches between Thursday and Saturday
mornings. This will most likely be in areas south of the Ohio River.

...FLOOD POTENTIAL DISCUSSION...
Flooding continues in the lower Ohio Valley. The potential for any additional
flooding in the short term is low. Late in the week and towards the weekend,
some significant river rises are expected.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain was fairly uniform across the entire basin with totals ranging 0.05 to
0.20 inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Precipitation is expected to be confined primarily to the northeast. Basin
averages will range from 0.10 to 0.35 inch in eastern Ohio, western New York,
western Pennsylvania and northern West Virginia.
