.AVIATION...
MVFR stratus has develop from the SAT-AUS area and northwest into
the Hill Country. The stratus will expand west toward the Rio Grande
overnight, developing at DRT after 09Z where is could become IFR
after 12Z with SHRAs potentially developing near the area.

Over the next couple of hours, TSTMs entering the far northern Hill
Country will continue southeast into the GTU-AUS corridor between
07Z-10Z. Some weakening is expected as they move into this area. A
tempo -TSRA group has been included in the AUS TAF.

A weak front will move into the Hill Country Saturday morning and
stall over southern areas in the afternoon. Additional SHRAs are
expected to re- evelop Saturday morning with possible TSRAs into the
afternoon and evening. Difficult to pinpoint exact locations and
times for TSRAs given model discrepancies in the frontal placement as
well as potential influences from mesoscale convective boundaries.
Generally VCTS is show in all TAF sites from the mid afternoon
through the evening.
