SHORT TERM...
(Tonight and Tomorrow)

Look for cool temperatures to continue for the next 24 hours. A weak
cold front will produce light northerly surface winds tomorrow.
However, surface winds until then will light and variable. Lows
tonight will be mainly in the mid 30s, except for along the
Interstate 10 corridor, where near-calm surface winds will enhance
radiational cooling. The weak cold front, and associated surface
cold air advection, will impact highs tomorrow, especially along and
north of the Interstate 20 corridor. There, highs around 60 look
likely. Elsewhere tomorrow, highs in the mid to upper 60s look good.

Huber

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

Good radiational cooling is expected Wednesday night, with
surface high pressure ridge extending from the eastern Plains
states south into central Texas. The coldest overnight lows
(upper 20s to 30 degrees) are expected in the low-lying areas
and river valleys of our eastern and southern counties. Light
southeast winds developing overnight will keep temperatures from
dropping off as much across the western Big Country.

Skies will be sunny on Thanksgiving, with temperatures recovering
into the 60s for highs, with southeast to south winds. A warming
trend is in store for the Thanksgiving holiday weekend, as the
upper level winds become zonal aloft and a broad, low amplitude
ridge gradually shifts east from the Desert Southwest across
Texas. Will have increased south-southwest surface winds, which
will result in warmer overnight lows as well. Should have highs
in the 70-75 degree range Friday, and into the lower to mid 70s
Saturday and Sunday, as 850mb thermal ridge builds east into our
area.

A dry cold frontal passage is progged Sunday night and early
Monday, but have some uncertainty on the forecast strength of
this front. The 12Z GFS and ECMWF bring an upper trough into the
western U.S. Monday into Tuesday. This system may affect our
area at the end of the forecast period or just beyond, as it
tracks east across the southwestern states and approaches Texas.
Models can be a little fast with the track of these systems, and
the preference for now is to keep PoPs just under 15 percent with
no mention of showers/thunderstorms yet for our area, Tuesday and
Tuesday night.
