.AVIATION...
/00Z TAFS/

Thunderstorms have yet to develop, but are expected to over the
next hour or so, affecting mainly the KBBD and KJCT sites between
00Z and 05Z tonight. Some of the storms will be strong to severe,
so have kept the TEMPO groups going for these sites with gusty
winds and reduced visibilities. Otherwise, west to southwest winds
this evening will turn northwest later tonight as a cold front
moves through, then to the north and increase into the 20 to 35
knot range, with VFR conditions. 20

SHORT TERM...
(Tonight and Thursday)

All eyes really focused on tonight and not going to deviate much
from the general idea that SPC has for the area. Dryline has moved
into West Central Texas this afternoon, but best wind speeds have
stayed across the Permian Basin and the far western Concho Valley
and Big Country so far. With only weak westerly winds, dewpoints
have only dropped into the 40s across the western portions of the
area and remain in the 50s/60s across the Heartland and Hill
Country. Latest hi-res models suggest that the dryline will stall
and shift a little farther west early this evening as the
convergence increases. Not sure it will make it all the way back
to San Angelo and Abilene, but its not gonna be too far away. Have
brought the mention of storms back farther west this evening, and
inserted the mention of severe into the Heartland and Hill
Country areas mainly southeast of a Coleman to Junction line.

Upper level low set to spin into the area late this evening as
well, with some high based showers and storms across Far West
Texas and New Mexico this afternoon. This will also move east
towards West Central Texas this evening, and although it will not
be severe, cant rule out a stray shower or storm surviving to
reach locations such as Sterling City, Sweetwater, and Haskell.
Thus, have added some small POPs across even the western Concho
Valley and Big Country.

Cold front surges south in the wake of the upper trough, with
north winds surging south across the entire area by sunrise
Thursday morning. Gusty north winds with highs in the 70s for most
locations on Thursday.

LONG TERM...
(Thursday Night through Wednesday)

Looks like mainly dry weather and warm temperatures through this
weekend. Highs will be mainly in the mid 80s to around 90 Saturday
and Sunday. Looks like for Tuesday and Wednesday, next upper
level trough(possibly slow moving), a stationary front, low level
moisture returning and increasing PW values to 1 to 1.5 inches
will bring a period or two of convection to West Central Texas.
The ECWMF is slower with the upper level storm system(closed 500
MB low) which would mean possible heavier rainfall for our area.
For now, going with chance Pops, but will probably have to be
increased if the medium range models continue on the wet side.
Also, maybe a little severe weather potential due to at least
moderate elevated instability in place, along with a surface
boundary just to our south, but still to far out to get into
details. Expect cooler temperatures by early next week with highs
in the mid 70 to lower 80s.
