.AVIATION...
(00Z TAFS)
Issued at 604 PM CST Fri Mar 6 2026

Today has seen the start of an active weather period for the
region. High pressure ridge over the northeast Gulf, feeling the
influence from longwave trof eclipsing the western US, has
started eroding east. As a result, scattered showers have
developed in southeast TX and cenLA. Not anticipating much to come
of these and any lingering convection will dissipate shortly after
00z. Even with the eastward move of the ridge, the pressure
gradient bwn ridge and strong trof has been ever tightening. Gusty
southeast winds will back off with sundown, but a southerly breeze
will prevail overnight. Winds will remain gusty off the sfc
overnight and into Saturday AM, though, due to interactions from
approaching trof. These strong gusts shouldn`t reach the sfc
until after sunrise Saturday when daytime heating can allow the
jet to mix all the way to the surface.

The strongest gusts this forecast period, away from any storms,
will be from roughly 13 to 20z. Wind speeds will diminish after
18z as the responsible jet leaves the region quickly.

Scattered showers and thunderstorms will be ongoing or will
rapidly develop in east Texas at sunrise while the jet is still
present. These storms will be far from directly impacting
terminals, but the widespread coverage along the front will impact
long haul routes.

Scattered showers and thunderstorms will develop over terminals
from mid day onward. Greatest hazards with strong storms will be
very large hail, heavy downpours and damaging wind gusts.
