Ohio River Basin Hydrometeorological Discussion

...HYDROMETEOROLOGICAL DISCUSSION...

Surface high pressure over the Ohio Valley this weekend will provide
dry weather conditions to the Ohio River Basin.

Wet conditions will develop early next week in response to a strong
storm system in the upper Mississippi Valley. A secondary piece of
energy moves thru the base of the big polar vortex over the Northern
Plains bringing another round of precipitation...especially to
drainages south of the mainstem about midweek.

These beneficial rains are not expected to produce flooding since
dry conditions have persisted this Autumn across the Ohio River Basin.


...FLOOD POTENTIAL DISCUSSION...

The potential for flooding is low thru the wet period next week.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...

Light lake effect precipitation occurred off Lake Erie generally
producing less than 1/4 inch in the Allegheny watershed as well as
the Lake Erie drainage near Cleveland.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...

Light lake effect continues today. Then...western 1/3 of the Ohio
River Basin becomes wet late in day 2 rainfall forecast (early
Monday morning).

...RIVER BASINS IN FLOOD...

None.
