Area Forecast Discussion...UPDATED
National Weather Service Huntsville AL
1225 PM CDT FRI MAY 27 2016

For 18Z TAFs.


 (Issued 1048 AM CDT FRI MAY 27 2016)
Another warm start to the day this morning with 10 am temperatures
already in the upper 70s to lower 80s. Most areas near and east of
I-65 are mostly sunny to partly cloudy. However, a fairly thick
canopy of high clouds is in place over northwestern Alabama at this
time. This will continue to move east slowly through the day and
should keep high temperatures lower than yesterday west of I-65. East
of I-65, since prevailing mostly cloudy conditions should hold off
until around 20Z or later, highs still will likely make it up to the
upper 80s/around 90 degrees.

Currently, there is a weak convergence boundary which extends from
eastern Kentucky through northern Georgia and west to just south of
the Franklin County in AL (likely a remnant outflow boundary from
convection yesterday and Thursday night). As heating continues this
morning and instability increases into the early afternoon hours,
isolated to scattered showers and thunderstorms could develop along
and near this boundary. Better coverage will likely be in the early
afternoon hours and east of I-65 associated with this boundary,
where better insolation will lead to better instability.

As the mid to late-afternoon hours continue, convergence and a
slightly stronger 925 mb jet should shift scattered precipitation
coverage west of I-65. The best convergence/instability will likely
be in Mississippi, but extend east into northwest Alabama. Some
stronger storms producing winds gusts around 45 mph are possible
along with frequent lightning.



For 18Z TAFs:

VFR conditions are expected to continue for the next 24 hours across
N AL/S Middle TN. Anticipating that southerly winds that have
increased to 10-15 kts gusting up to 22 kts will continue until
28/01Z when they diminish to 5-7 kts. There could be isolated-
scattered t-storms btwn 28/18Z-28/01Z with amendments possible to
TAFs if these develop or move towards the terminals. Better chance
for scattered storms may return late in the forecast beginning
around 28/10z through the end of the forecast as a weak disturbance
moves across the region. Have included VCTS for that possibility in
the forecast.
