SHORT TERM...
(Today and Tonight)

Surface high pressure over West Central Texas today will move
east into Central Texas tonight. This will allow north winds of 10
mph or less to shift southeast and south overnight. Highs today
will be in the lower 70s.

Good radiational cooling conditions will present tonight,
especially across eastern sections...along and east of Junction to
Brownwood line. This region will have light winds through much of
the night, with lows expected in the lower 40s.

LONG TERM...
(Monday through next Saturday)

Warmer this week after the cool temperatures this weekend. The
upper level pattern will be fairly progressive through the end of
the week, with a shortwave trough moving through the area
Wednesday, and an upper level low affecting the area at the end of
the week.

Monday and Tuesday, 850mb temperatures warm from 10-15 degrees
Celsius Sunday afternoon into the 15-20 degree range Monday
afternoon and to around 25 degrees Celsius by Tuesday afternoon.
This will result in highs warming well into the mid 90s by
Tuesday, with some readings in the upper 90s not out of the
question. Winds will also pick up out of the west, resulting in
elevated to near critical fire weather conditions, especially west
of a Haskell, to Abilene, to Ozona line.

Tuesday night into Wednesday, an upper level trough will quickly
move across the central U. S., and send a cold front into west
central Texas. Highs Wednesday will range from the low 70s north
of I-20 to the mid 80s along and south of I-10. Although we will
have a front moving through, dry low level air ahead of the front
will limit rain chances for our area.

Thursday and Friday, winds quickly turn back around to the west
and southwest, warming temperatures back into the upper 80s to mid
90s.

Then, by Friday evening, an upper level low will move southeast
into the four corners region. The slower speed of this upper level
low will allow Gulf of Mexico moisture to work back into the area.
As an attendant Pacific cold front moves through Friday night into
Saturday, we will have a chance for showers and thunderstorms
across the area, mainly north of a San Angelo to Brownwood line at
this time.
