.DISCUSSION...

Currently...500 mb low is centered over Nebraska with upper ridge
over the Southeast U.S. A weak shortwave is moving through the
Mid-South but the airmass has stabilized and just a few showers
are occurring. Skies are mostly cloudy and temps range from the
upper 60s to lower 70s.

Today through Monday...The upper low will track northeast toward
the Upper Mississippi Valley. Upper level heights will rise and
moisture advection into the region will weaken. Precipitable water
values will start to drop today. Expect the coverage of showers
and thunderstorms will be less than previous days along and west
of the Mississippi River. Areas toward the TN River and Northeast
Mississippi which have been relatively dry for the past few days
will stand a slightly better chance of seeing rain today as the
axis of deeper moisture shifts southeast. Some sunshine will mean
more instability this afternoon...especially along and west of the
Mississippi River...so a few strong storms with gusty winds are
possible. Any convection will dissipate with loss of heating this
evening followed by clearing skies and lows in the 60s. Sunday and
Monday look like a diurnal convection days with no disturbances to
key off of. Expect mainly isolated afternoon storms and temps in
the upper 80s. Sunday night should be quiet and mild with lows in
the mid and upper 60s.

Tuesday through Friday...Toward the middle of the week medium
range models have a mid level trough moving through the plains
with disturbances starting to move through the Mid-South. As a
result shower and thunderstorm coverage will start to increase. A
few strong storms are possible. Expect warm and humid conditions
to continue with highs in the 80s and lows in the mid and upper
60s. Trough axis and cold front will push through the Mid-South
Thursday/Friday time frame with chances for showers and
thunderstorms and cooler temps.

.AVIATION...

06Z TAFs

Airmass had stabilized over the Midsouth this evening, in the
wake of TSRA that earlier moved up the delta, and with the loss
of surface heating. Low level mixing should should be sufficient
overnight to keep winds from completely decoupling under broken
midlevel cloudiness.

00Z NAM Bufr soundings depict a slightly stronger convective cap
for Saturday afternoon, precluding a TEMPO mention for thunder at
this time.
