.DISCUSSION...
 (Issued 806 PM CDT Wed Sep 28 2016)
Latest observations show the cold front is entering northern Alabama
as of 01Z. The front will continue to push south through the area
over the next 1 to 3 hours and be completely through the area by
midnight. Expect winds to increase along and immediately behind the
front with speeds increasing to around 20 mph with brief gusts to 25
mph possible. Slightly breezy conditions will continue through the
overnight and while this would typically allow for better mixing and
prevent temps from falling too far, excellent cold air advection
behind the front will send temperatures tumbling down into the 50s by
sunrise Thursday. Took a quick look back at some of the stats and
this should be the coldest night for the TN Valley since mid to late
May of this year. It will be a crisp fall morning tomorrow.

In terms of PoPs and Sky for tonight, radar trends show little
westward development of showers to our north. As the upper level low
shifts south the main energy and upper level jet streak driving the
showers will shift east. This should keep PoPs out of the area except
for a sliver of southern middle TN. Adjusted cloud cover for tonight
to increase with the passing of the front and then decrease behind
it. The strato-cu under the core of the upper level low are not
expected to make it into the area until late Thursday morning. The
rest of the forecast is in good shape and no other updates are needed
at this time.

.AVIATION...
For 06Z TAFs: The cold front has moved completely through the area.
Winds will continue to be breezy through 06-07Z then begin to drop
off and remain below 10kts through the overnight period. The clouds
associated with the front will scatter out leaving clear skies and
VFR conditions.

As the upper level low over the midwest shifts south tonight into
Thursday expect winds to ramp back up after sunrise Thursday. Gusts
upwards of 20kts will be possible at times out of the north. A
scattered to broken deck of clouds AOA 4,000 ft is expected to form
over TN during the day Thursday and some of these clouds should
filter south and move over the terminals.
