.AVIATION... (12/06Z TAFs)
MVFR CIGs developing near KSAT will spread to all I-35 sites in the
next couple of hours. There is a potential for brief IFR, however,
will go only SCT at that level for now. Model trends keep any CIGs
east of KDRT and have only gone SCT. Will update if trends indicate
CIGs there. All sites go FEW-SCT VFR by midday Saturday. S to SE
winds prevail at 5 to 10 KTs, except 10 to 15 KTs with gusts to 25
KTs at KDRT on Saturday. There is uncertainty on MVFR CIGs Saturday
night at the I-35 sites as winds turn more to S-SW and have only
SCT indicated.

SHORT TERM (Tonight through Saturday Night)...
24 hour temperature differences across south central Texas show
little change from yesterday, except out west along the Rio Grande.
Clouds have managed to clear earlier today vs. yesterday along the
Rio Grande, so temperatures are running warmer. We are still on
track to see afternoon high temperatures near 100 along the Rio
Grande, with 90s for the remainder of the region. It will be warm
and humid once again tonight, with low clouds developing over most
areas early Saturday morning. Look for lows in the 70s, with near 80
along the Rio Grande. Continue warm and humid on Saturday and
Saturday night with highs in the lower 100s along the Rio Grande,
with 90s elsewhere. We will go with more of a persistence forecast
for overnight lows Saturday night, with 70s to near 80 for all
areas.

LONG TERM (Sunday through Friday)...
The summertime pattern will remain in place Sunday with little change
for South Central Texas. Monday the upper level ridge will begin to
shift a bit to the west and allow a weak cold front to slide down
into East Texas. This front will stall in that area for much of next
week. This will mean low chances for showers and thunderstorms each
afternoon for eastern parts of our CWA. Most of the region will
continue to have dry weather. The reduced subsidence will mean
temperatures will be a few degrees cooler dropping to near or below
normal.
