Ohio River Basin Hydrometeorological Discussion
Ohio River Forecast Center, Wilmington, Ohio
1222 PM EST Sunday, January 15, 2017

...HYDROMETEOROLOGICAL DISCUSSION...
Moisture is streaming into the lower Ohio Valley ahead of a strong storm
system currently in the Southern Plains. Light rain is falling north of a
front draped over the TN Valley. That front will lift north as a warm front
Monday bringing warmer temperatures and more widespread rain to the basin
by Monday night.

On Tuesday, the low pressure system will lift from the Mid-MS Valley into the
Great Lakes, nudging a cold front into our region. The front will get
hung up a bit until a secondary wave of low pressure arrives Tuesday night,
finally forcing the front to exit the region Wednesday. Because of the
slow moving nature of the frontal boundary, rainfall amounts could be
heavy, particularly for areas south of the Ohio River. A day or two of
dry weather is expected behind the system, along with above normal
temperatures.

...FLOOD POTENTIAL DISCUSSION...
Minor flooding from recent rains continues across parts of Indiana, eastern
Illinois, and Ohio. The flood potential elsewhere will remain low for the
next day or two. More widespread flooding is possible beginning Tuesday as
the next rainfall event moves through the basin.

...24-HR OBSERVED PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain affected all but the far northern Ohio Valley. Amounts generally
ranged from 0.10" to 0.50".  Heavier amounts of 0.50" to 1.00" were
reported in parts of KY and WV.

...48-HR FORECAST PRECIPITATION USED IN TODAY`S RIVER FORECASTS...
Rain is forecast basin-wide. Heaviest amounts are forecast across the western
basin with between 0.25" to 0.75".  The eastern basin should receive
under 0.25" through Tuesday morning.
