SHORT TERM...
(Today and Tonight)

The main forecast problem will be patchy dense fog across much of
the Big Country and Heartland this morning. Going with dense fog
advisory until 10 AM. However, 11-3.9 micron satellite imagery and
current observations indicates fog is dissipating in the advisory
area. If this trend continues, may cancel the advisory early.

Otherwise, a quiet forecast for the next 24 hours across West
Central Texas. A weak cold front will move across the area
tonight, clearing the I-10 corridor after midnight. Highs today
will be mainly in the 60s, with overnight lows in the 30s and
40s.

LONG TERM...
(Tuesday through Sunday)

The cold front that will move across the area tonight will stall
south of the area on Tuesday. Meanwhile, an upper low over northern
Mexico will move slowly towards the region through Wednesday.
Ahead of this system, scattered showers and isolated thunderstorms
are expected to develop Tuesday into early Wednesday as isentropic
ascent increases north of the frontal boundary and weak
disturbances lift northeast across the area. Best rain chances
will be across the southeast half of the forecast area Tuesday
and Tuesday night, with precipitation ending across southeast
counties on Wednesday. Highs Tuesday will be in the lower 50s,
with highs on Wednesday mainly in the upper 50s.

Warmer and breezy weather is on tap Thursday through Saturday,
with highs in the 60s and lows in the 40s. The medium range models
show another shortwave affecting the area over the weekend, which
may additional rain chances to the area. For now, keeping slight
POPs in the forecast for Saturday night.
