.DISCUSSION...
 (Issued 1102 AM CDT TUE MAY 31 2016)
Current radar trends show that the showers and thunderstorms in NE
MS continue to slowly move NNE and are weakening as they get closer
to the AL border. Temps have climbed up into the 80s but dewpoints
have fluctuated over the past few hours around 60 degrees. The higher
pool of PWATS (1.5 inches) is currently to our west as we are still
slightly drier. The outflow boundary from the batch of convection in
MS is currently moving into NW AL and could be a lifting mechanism
for a few showers or storms. The combination of the outflow
boundary, weak shortwave and isentropic lift will allow for
development of isolated showers and thunderstorms though this
afternoon. Therefore, have updated the POP/wx grids to reflect this
thinking. With the additional cloud cover, high temps will be near
or just below yesterday`s highs...so look for temps around 90
degrees.

.AVIATION...
For 18Z TAFs: An outflow boundary with a few showers/storms is SE of
KMSL and moving toward KHSV. Will include VCTS and a tempo for
higher winds after 19z to account for this boundary at KHSV. Once it
passes, winds will diminish again to less than 5kt. Will also include
VCSH after 21z at KMSL for showers slowly moving from NE MS eastward.
CIGS should generally remain VFR outside of a brief lowering in a
thunderstorm.

Isolated showers are possible after sunset and overnight but coverage
and confidence is too low to include in the TAFs at this point and
will handle any development with amendments.
