.AVIATION...
For the 24/06z TAFs, mid and high level clouds will prevail for
most of the TAF period. However, showers are beginning to develop
across Central Texas ahead of an approaching upper trough. As this
trough ejects from the Rockies and into the Plains, the showers
will spread from southwest to northeast across the area during the
day Wednesday. All TAF sites will be affected. Showers should
begin at KLFK around sunrise and should reach KELD and KMLU late
in the period. Expect ceilings to lower into the MVFR category at
all terminals after 26/00z as the rain prevails.
