This Hazardous Weather Outlook is for portions of Middle
Tennessee.

.DAY ONE...This Afternoon and Tonight

Several rivers, creeks and stream across mid state will
continue to experience flooding or elevated levels
through tonight.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday

A strong frontal system will work across middle Tennessee on
Wednesday. Enough instability may be in place by the afternoon
and evening hours whereby strong to severe thunderstorms could
develop. Currently, the best chance of severe weather will be
across southern and eastern areas with hail and damaging winds
being the primary threat, although the development of a few
tornadoes can not be totally ruled out.

In addition to the severe weather threat, total rainfall amounts
of 1 to 2 inches with locally heavier amounts possible on top of
a very saturated ground will lead to an increasing threat of
flash flooding Wednesday afternoon into Wednesday night and
across the Cumberland Plateau Region through mid morning hours
on Thursday. A Flash Flood Watch has been issued for mid state
as a result during this time period. Also, already elevated
levels on several area rivers, creeks, and streams will worsen.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed on Wednesday afternoon
and into Thursday morning for potential flooding and
for strong to severe thunderstorms Wednesday afternoon
and evening.
