.DISCUSSION...
(Issued 957 PM CDT Tue Sep 27 2016)
Current short term forecast grids are in good condition this evening,
with no updates planned at this time. Surface ridge will continue
to settle into the region overnight, providing an excellent
combination of ingredients for radiational cooling -- as calm winds
will work in conjunction with clear skies and a dry boundary layer
airmass to provide cool temps to the entire region by sunrise.
Temperatures have already fallen into the upper 50s across our TN
counties, and would not be surprised to see lows fall into the upper
40s in the sheltered valleys of southern TN and northeast AL.

.AVIATION...
For 06Z TAFs: No changes to previous aviation forecast reasoning.
VFR/SKC conditions and lgt/vrbl winds will prevail at both
terminals overnight. Sw winds will increase to arnd 10 kts by 28/15Z,
along with a gradual increase in mid and high-lvl clouds. A stronger
reinforcing cold front will approach from the northwest late tomorrow
aftn, with sfc winds expected to weaken and veer in advance of the
front. Winds will increase and shift to nnw at MSL/01Z and HSV/02Z,
with an increase in stratus clouds expected during this period as
well. Threat for isolated shra appears highest to the n/e of the
airports, and will not include pcpn in either TAF attm.
