.DISCUSSION...
(Issued 159 AM CDT TUE JUN 28 2016)
At 2 am, local radars were showing only some isolated light shra
mainly across nern AL. The band of shra/tsra that were over portions
of nern TN earlier continues to drift to the east and dissipate.
Temps across the cwa were in the lower 70s with near 70 dewpoints.
Stlt is showing that stratus clouds were increasing in coverage
across the cwa which should keep widespread dense fog to a minimum
over much of the cwa. However in our higher elevations the fog may
get fairly dense at times.

Otherwise a cdfnt over nrn MO will continue to drop south today and
should be entering our cwa by the late aftn and then out of the TN
Valley around midnight. Models are showing that the best chc of pcpn
should be south of the TN Valley today. However for now kept low
pops in this mrng for all of the cwa and just in our extreme sern
zones for this aftn. Cant rule out an isolated shra/tsra this
evening as the cdfnt moves thru, but attm the chc looks too iffy.
Will let the dayshift take a closer look to see if a low pop will be
needed tonight.

Behind the cdfnt on Wednesday/Thursday, temps will be a little cooler
but the dewpoints will drop into the upper 50s/lower 60s making for
less humid conditions. Also no rain is expected during this period.

Friday thru Monday, GFS and ECMWF for the last couple of days
continue to show that Friday should be rain free. Thus will keep
Friday dry. Saturday thru Monday looks to be an unsettled wx pattern
shaping up as a cdfnt and a few upper disturbances approach the TN
Valley. On the 4th of July may have a chc of sct shra/tsra but its too
early for any details attm.

.AVIATION...
For 12Z TAFs: A cdfnt will begin to push across the cwa by late this
aftn and then out of the TN Valley arnd midnight. Models are keeping
the chc of pcpn mainly south of the taf sites for today. The chc of
pcpn tonight will also be very low. Thus will not include any pcpn
in tafs for today or tonight. However model soundings do show a
possible sct/bkn deck of clouds arnd 3000 ft by 09z. Otherwise mvfr
with occasional ifr ceilings will continue until arnd 18z. After 18z
expect mainly vfr conditions.
