AVIATION...
/00Z TAFS/

Expect MVFR conditions for the southeastern terminals through
most of the night with VFR conditions expected for the remaining
terminals through late evening. A squall line will move west to
east through West Central Texas late this evening through most of
tonight. Severe thunderstorms are possible with this line,
especially for the Abilene terminal. Expect sunny skies and gusty
west winds to develop by mid to late morning as a pacific front
moves east across West Central Texas.

PREV DISCUSSION... /issued 316 PM CST MON NOV 16 2015/

SHORT TERM...
(Tonight and Tuesday)

.Severe Weather Possible tonight...

West Central Texas will see a significant weather change during
the next 24 hours. An upper-level storm system and associated cold
front will move across West Central Texas, from west to east,
tonight. Showers and thunderstorms will begin to develop later
this afternoon, across the Permian Basin and Trans Pecos region to
our west. Then, as the cold front pushes across West Central
Texas, mainly between the hours of 10 PM and 2 AM, a line of
showers and thunderstorms will move with this front. Some
thunderstorms may produce damaging winds exceeding 60 mph. Surface
based CAPEs, along and just east of the surface front, could range
as high as 1000 to 1500 J/Kg. In addition, the zero to 6km bulk
shear may range as high as 55 to 65 knots. Although the
corresponding potential is low for large hail and tornadoes,
thunderstorms this evening and overnight could produce either of
these. The primary area for these threats lies generally along and
north of a San Angelo to Richland Springs line; but, the area of
greatest threat lies along and north of Interstate 20. As the
front moves across West Central Texas quickly overnight, gusty
winds from the west will develop. For tomorrow, expect sunny skies
and gusty winds from the west, with afternoon highs in the mid to
upper 60s.

LONG TERM...
(Tuesday night through next Monday)

Generally quieter weather expected in the long term forecast.
Tuesday night, with drier conditions, clear skies, and light winds
behind the cold front, we are expecting lows to fall into the 30s
in our southern valley locations, while lows near 40 should be
common elsewhere.

From the middle of the week through Friday, northwest to zonal
flow aloft will result in dry conditions, and mild temperatures.

Friday night, the first true taste of Canadian air will move into
west central Texas, with much colder temperatures expected
Saturday. Right now, we have highs in the upper 50s to around 60
for Saturday, but highs could be cooler than this. One model is
suggesting temperatures remaining in the 40s throughout the day
Saturday. There will also be a chance for some showers along and
behind the front Saturday into Sunday. However, confidence is low
in precipitation chances at this point. Temperatures should
rebound pretty quickly with highs getting back into the mid 60s to
near 70 by next Monday.
