.DISCUSSION...
The morning visible satellite imagery depicts an extensive
stratocu field that continues to linger across much of Deep E TX,
N LA, and Scntrl AR, with additional cu cigs developing farther N
across SW AR and portions of E TX as they sink S in wake of the
nearly stacked low pressure system over Middle TN. The 12Z KSHV
raob does depict a fairly saturated air mass up to H800, with the
12Z NAM having initialized well on the post-frontal stratocu and
depicts additional cu developing through early to mid afternoon
before the deeper/drier air is able to mix farther S into Srn AR/E
TX/extreme Nrn LA.

A zone update was needed this morning to significantly beef up sky
cover this afternoon, with cu cigs likely lingering across much of
Ncntrl LA. Did show more of a gradual decrease in cloud cover over
Lower E TX/Wrn LA/Srn AR by mid to late afternoon, where the cigs
should scatter out. Did maintain partly cloudy conditions through
early evening over the Ern sections of Ncntrl LA before the sky
is able to clear. Otherwise, a somewhat tight pressure gradient
will linger through the afternoon ahead of the building sfc ridge
over the Srn Plains, with the winds expected to relax at/shortly
after sunset. 15Z temps were also running 1-2 degrees warmer than
anticipated over much of the area, and given this, have bumped up
max temps slightly to compensate as the cold advection has ended.
All in all...a great and comfortable day with below normal temps
is on tap before we return to reality (above normal temps and
higher RH`s) Monday and especially afterwards.

Zone update already out...grids will be available shortly.
