Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1216 PM EDT Friday, July 3, 2015

...HYDROMETEOROLOGICAL DISCUSSION...
Several waves of low pressure will slide across the southern Ohio Valley
today through the holiday weekend. As a result, unsettled weather is
forecast primarily for areas along and south of the Ohio River. Some storms
could produce heavy rainfall totals of 3" to 5". Meanwhile, high pressure
centered over the Great Lakes will keep much of the northern basin dry.

Conditions will be drier from late Sunday through Monday.

A cold front is expected to sweep across the region next Tuesday bringing
more widespread precipitation. Another front may push through at least the
northern Ohio Valley late next week.

...FLOOD POTENTIAL DISCUSSION...
Minor to moderate flooding continues across the western and northwestern
Ohio Valley as well as a couple of isolated points in western Kentucky.
Rivers here will be slow to recede and should linger above flood stage
for several more days.

With thunderstorm activity sagging mainly into the southern basin, the risk
of new river flooding will shift southward as well.  However, the main
threat will likely be urban/flash flooding.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rains fell across an area along and south of the Ohio River. Some basin average
amounts in middle Tennessee and portions of Kentucky reached the 1.50 to 3.00
inch range.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast across all but the far northwest, however significant rains
will be confined to middle Tennessee and southern Kentucky where basin averages
will range from 0.75 to 1.50 inches.
