(Tonight and Sunday)

Dry conditions and colder temperatures will dominate for the next 24
hours. An upper-level trough will continue to move slowly east
across Texas tonight. As this system moves over West Central Texas,
it may create conditions favorable for addition precipitation,
mainly west of a line from near Sweetwater to near Junction. If
precipitation does develop...models indicate it will likely be light
rain. However, with colder temperatures dominating Irion county and
much of Crockett county, a wintry mix of precipitation is possible
there tonight. However, we do not expect any accumulation. Lows
tonight ranging from the mid 20s north of our Interstate 20
corridor, to around 32 along our Interstate 10 corridor, look
reasonable. Also, surface winds tonight will diminish and slowly
begin to back, as a surface high pressure center begins to move east
across south Texas. For tomorrow, look for decreasing clouds, with
highs from the upper 40s to the lower 50s. Surface winds will
continue to be light and back slowly, as the surface high moves
farther east.


A strong cold front will move through Monday night, with cold air
building in at the surface through the middle part of the week.
The main potential for winter precipitation will be freezing
drizzle, possibly mixed with sleet. A few flurries are possible
Thursday in the Big Country as the upper system approaches.
For the most part, however, warm mid level temperatures will limit
the potential for snow this week.

The main hazard will be icy bridges and overpasses. Ice
accumulations however, if any, should be light. Best rain amounts
will be Thursday night into Friday as the system passes northeast.

While the wintry potential with this system appears limited at
this time, if there remains uncertainty in the track and timing
of the upper trough from the west. Small changes in the track of
the trough could produce a higher potential for heavier snow or
freezing rain amounts.

Drier and warmer conditions are expected next weekend with passage
of the upper system and return to surface southerly winds.
