Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1123 AM EDT Thursday, July 2, 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.
A cold front may sweep across the region next Tuesday bringing more
widespread precipitation.

...FLOOD POTENTIAL DISCUSSION...
Minor to moderate flooding continues across the western and northwestern
Ohio Valley.  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...
Showers and thunderstorms affected much of the western and southern Ohio
Valley. Parts of IL, IN, KY, and TN received 1" to 3" with locally heavier
amounts over 4". A large portion of the central and northern basin was dry.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Heaviest rainfall totals are expected in KY, TN, southern WV, and western
VA with 1" to 3" possible. The middle tier of the Ohio Valley should see
0.10" to 1.00" on average, while much of the northern third will be dry.
