.DISCUSSION...
(Issued 1054 AM CDT WED JUL 27 2016)
Low cloud cover pushed in this morning allowing for temps to run a
few degrees behind yesterday`s trend with current obs in the lower
80s around the TN Valley. With this trend, adjusted cloud cover and
hourly temps accordingly. Even though the radar looks clear, isolated
light rain showers have been reported over the past hour or so as the
low stratus deck progresses northward.

With the TN Valley on the western edge of the ridge stationed in the
southern Atlantic, the combination of a weak disturbance and
enhanced WAA and moisture advection will increase our precip chances
throughout the day. NE AL however will have lower coverage in
convection this afternoon as water vapor satellite highlights drier
air more so over the area. Convection coverage and continued cloud
cover will play a role in temperatures today. Upper 80s for most to
around 90 degrees for those that break out of cloud cover or don`t
see any rainfall.

.AVIATION...
For 18Z TAFs: vfr conditions are expected for several more hours at
both taf sites. However...later this afternoon around 27/20Z expect
scattered -TSRA to develop at both TAF sites. A more concentrated
area of activity should push into KMSL after 27/22Z and bring MVFR
cigs to the terminal and closer to 28/00Z at KHSV. During the evening
hours, CIGS/VSBYS could lower further to IFR conditions or worse at
times, especially at KMSL. Expect MVFR CIGS to continue overnight at
both locations. Some guidance suggests cigs overnight could drop to
IFR or less. Another round of -TSRA is possible at KMSL around
midnight. For now only went with a PROB30 group between 28/05Z and
28/08Z to account for this. Winds will become more southwesterly on
Thursday.
