Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
130 PM EDT Saturday, October 21, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
One more dry day is forecast today before an approaching cold front brings
showers to the western basin tonight and Sunday. Strong low pressure will
move northeast through the region on Monday with widespread rain and
possible embedded thunderstorms. Rainfall could be heavy at times. The low
lifts away from the Ohio Valley Tuesday as a much cooler airmass settles
into the basin. Scattered showers will continue into midweek as a trough
digs into the eastern US.

...FLOOD POTENTIAL DISCUSSION...
There is no threat of flooding through the weekend, but the risk will
increase early next week with the potential for heavy rain.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
None.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast across the western third of the basin. Amounts will be
heaviest over the extreme lower Ohio Valley with 1" to 2" possible. Amounts
taper off quickly to the east.  The central and eastern basin will be dry
through Monday morning.

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