.SHORT TERM...
(Today and Tonight)

A fairly quiet weather pattern will be in place over the next 24 
hours, as southwesterly surface flow sets up across West Central 
Texas. A weak upper-level shortwave trough and a broad area of low
pressure at the surface will traverse the Central and Southern 
Plains today. This will bring nothing more to west Texas than a 
slight increase in southerly winds today, turning southwest this 
afternoon. The southwest winds will bring warmer air into the 
region, allowing high temperatures to get to around 60. With the 
exception of some low clouds this morning along the I-10 corridor,
skies should be mostly clear today. Overnight, as the broad area 
of low pressure moves east, winds will remain in the 5 to 10 mile 
an hour range and turn out of the west. Temperatures should be 
warmer than the past couple of nights; only in the low 40s.

.LONG TERM...
(Friday through next Wednesday)

Dry and warmer weather for Friday through Sunday, followed by
cooler and continued dry conditions for the first half of next
week. 

Winds will increase and become gusty out of the west/northwest 
Friday as winds line up from the surface through the mid levels, 
and good mixing allows faster winds to reach the surface. The 
downsloping westerly winds combined with ample sunshine will allow
for temperatures to warm into the upper 60s to mid 70s, and 
temperatures may need to be warmed in subsequent forecasts for 
Friday. Warm and dry weather continues for Saturday with highs 
again expected to be in the upper 60s to low 70s. On Sunday, the 
next upper level trough to move by the area will be moving east 
across the Four Corners region. South to southwest low level flow 
ahead of the trough should result in one more warm day across the 
area. Behind the upper level trough, the next significant cold 
front will move through. With most of the upper level energy to 
our north, and little moisture to work with, this should be a dry 
cold frontal passage. The ECMWF and GFS have gotten closer 
together in the timing of the front, but the ECMWF is still 
roughly 6 hours faster. At this point, the front is expected to 
move through during the Sunday night time period, so both models 
still show the colder temperatures holding off until Monday. After
a warmer than average weekend, Monday through Wednesday next week
look to be slightly cooler than average as far as temperatures 
are concerned, with continued dry weather.
