Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
855 AM EST Wednesday, January 18, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Two significant weather events are queuing up to affect the Ohio Valley into
next week.  The first system will begin late tonight as it begins to push into
the southwest basin, and will exit the region late Friday.  This will affect the
western part of the service area the most.  The second system is expected to
begin Sunday night and continue into Tuesday.  This is expected to impact the
eastern half of the basin the most.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding is forecast or occurring across much of the western basin.
With a warm and active weather pattern in place for the next week or two,
the threat for flooding will remain elevated the rest of the month.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain, and some snow, fell over about half of the Ohio Valley in the 24 hours
ending near daybreak today.  Most of the activity was in the southeastern half
of the basin and amounts were mostly under a half inch.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Forecast rainfall amounts exceed 1.5 inches in the southwestern basin with a
widespread inch or so expected northward through the western half of Indiana.
Amounts in the northeastern basin will be minimal as the system weakens by the
time it reaches there.

...RIVER BASINS IN FLOOD...
Points along the following river basins were in flood Wednesday morning:
