Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1220 PM EDT Tuesday, September 27, 2016

...HYDROMETEOROLOGICAL DISCUSSION...
The Ohio Valley is between weather systems today. Generally quiet
conditions are expected.  On Wednesday, a broad area of low pressure will
drop into the region, bringing the chance of showers and possibly embedded
thunderstorms to the area - and keeping temperatures at or below normal the
rest of the week.  The low will finally exit the region late this weekend.
Rain with this stubborn disturbance will not be terribly heavy, but will
persist for several days. The highest rainfall totals through the event
will likely be in the northeast Ohio Valley. Amounts here in western PA,
western NY, and northeast OH could range from 1" to 3". Elsewhere, around
0.50" or less will be common.

...FLOOD POTENTIAL DISCUSSION...
Flood potential is low.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain was widespread throughout the basin. Most locations received
under 0.50" with locally heavier amounts up to 0.75" in southern IN and
western KY. Even heavier totals exceeding 1" fell in the southeast Ohio
Valley.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast for nearly the entire Ohio Valley. Basin average amounts will
be 0.25 inch or less in the west and 0.10 to 0.50 inch in the east.

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