SHORT TERM...
(Today and Tonight)

Gusty north to northwesterly winds of 15-20 mph with gusts of 25-35
mph continue to occur early this morning as a strong surface
pressure gradient is in place due to a strong high over the
Panhandle and low pressure over the Gulf. The winds continue to
bring cold air to the forecast area, so expect lows this morning to
be in the upper 20s to low 30s and wind chills in the upper teens to
low 20s.

As the day goes on, the surface high will move south into the
Permian Basin keeping the cold air advection via gusty northerly
winds going. Expect sunny skies today and chilly highs in the upper
40s to around 50. The high moves over our region in the evening,
resulting in the pressure gradient and winds quickly and
dramatically weakening. The weak winds, clear skies and cold air
mass tonight will result in a good radiational cooling setup, so
expect lows in the low to mid 20s south of the Big Country and upper
20s in the Big Country.

LONG TERM...
(Thursday through Tuesday)

On Thursday, gusty southwest winds develop by midday as a tighter
pressure gradient develops between surface high pressure over
South Texas and a lee trough along the Texas and New Mexico state
line. This will bring slightly elevated fire weather conditions.
It will also bring a strong diurnal temperature change, with early
morning lows in the lower to mid 20s, rising to highs in the
lower 60s.

Temperatures will continue to warm into the weekend, with highs of
65 to 70 Friday, lower 70s Saturday, and upper 70s to lower 80s
Sunday. An upper level trough over northern Baja California
Monday will move east across the region into Tuesday, bringing a
chance of showers and isolated thunderstorms. Rain and clouds will
bring down highs Monday. A weak cold front Tuesday may also affect
the Big Country.
