Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1129 AM EDT Thursday, May 21, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
Light showers are falling across the far eastern Ohio Valley associated with a
departing disturbance.  Another weak system will swing through the Great
Lakes tonight and Friday providing more light showers for the northeast
basin.

High pressure builds in for Saturday,  but a warm front brings showers and
thunderstorms back to mainly the western and northern Ohio Valley Sunday.
Unsettled conditions could then linger much of next week as a warm, moist
airmass interacts with a stalled front.

...FLOOD POTENTIAL DISCUSSION...
Flood potential remains low through the weekend.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Showers were widespread across the region. Amounts were generally light
remaining under 0.15" most places.  However, parts of western KY and
middle TN received between 0.25" to 1.25".

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Light showers across the eastern third of the basin will produce anywhere
from a couple hundredths up to 0.20".  The western 2/3rds will remain dry.

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