Areas affected...upper OH Valley

Concerning...Heavy rainfall...Flash flooding likely

Valid 160730Z - 161030Z

SUMMARY...Moderate to heavy rain will continue to translate east
through the upper OH Valley in the short term with an additional
inch of rain through 1030Z. Renewed flash flooding is expected.

DISCUSSION...0730Z radar imagery showed a leading linear segment
of heavy rain moving through eastern KY, followed by a stratiform
region of moderate to heavy rain over eastern KY. As a low level
vorticity max advances northeast from Middle TN, an 2-3 hour long
duration of stratiform moderate to heavy rain is expected to
advance into eastern KY, southern OH and eventually portions of
western WV. In addition, preceding the stratiform region will be a
leading line of showers with embedded thunderstorms which have had
a history of 0.25 to 0.50 in an hour but with a 0.25 inch or more
in 15 minutes over eastern KY.

As the entire envelope of rain translates toward the
east/northeast, additional totals up to about an inch are expected
through 1030Z, with a likelihood of renewed flash flooding or a
continued/worsening of ongoing flooding concerns occurring from
heavy rain which fell over the past 24 hours.
