AVIATION...
/12Z TAFS/

Showers with isolated thunderstorms will continue the next 24
hours. Ceilings will gradually lower to MVFR this morning. San
Angelo and Abilene ceilings are expected to IFR this afternoon as
a cold front moves through. Southern terminals should fall to IFR

SHORT TERM...
(Today and Tonight)

Potential flooding continues to be the main weather threat through
tonight. An upper low west of El Paso will continue to bring upper
level divergence over the region. Precipitable water values
remain high at 1.5 to 2 inches. A cold front will push through the
region this afternoon, providing a low level focus for
development. Additional rainfall amounts of 2 to 4 inches are
possible over the Concho Valley, Crockett and Sutton Counties.
Additional rainfall amounts of 1/2 to 2 inches are possible
elsewhere. Will keep same flash flood configuration through 7 AM
Monday.

LONG TERM...
(Monday through Tuesday)

.Flash Flood Watch Extension Possible...

Very promising rain chances will continue across all of West
Central Texas for Monday, with decreasing chances into Monday
night and Tuesday. Models indicate precipitable water values on
Monday will remain high, especially for our southwestern counties.
Thus, extending the Flash Flood Watch into Monday, for some of our
counties, is a possibility. For Monday night and Tuesday, rain
chances diminish, as the upper low to the west retrogrades farther
west, and high pressure begins to build over Texas.

(Tuesday night through Saturday)

.Dry...

The remainder of the long term is dry, with temperatures very
close to seasonal normals. High pressure will build over the
region, from Wednesday through the end of this work week, as an
upper ridge dominates the Plains. By Friday and into Saturday,
the upper ridge does weaken, and flow aloft over Texas becomes
more zonal. However, models indicate the dry pattern will
continue into the start of next weekend.
