Southwest Texas.

.PREVIOUS DISCUSSION... /ISSUED 313 AM CST Mon Dec 15 2014/

DISCUSSION...
The upper low/trough that brought the wind to the area yesterday is
moving off to the northeast this morning with high pressure building
in behind it.  This will result in mild wx for the region the next
few days.  Another upper trough moving down the West Coast Wednesday
will swing over AZ and into NM on Thursday bringing our next shot of
rain.  A third upper trough dives down across the Rockies over the
weekend and may bring colder wx and another chance of precipitation
to the region.

Will start the day on the backside of the Pacific front with a west
wind across the area.  High dewpts have been pushed well to the east
with a dry airmass over the region.  A backdoor front will push in
tonight as a surface ridge builds south.  This will result in an
east wind across the area and cooler temperatures Tuesday.  The wind
will slowly come back around to the south and temps will begin to
warm as a new leeside trough develops.

High temperatures will be in the 60s today falling to the 50s for
much of the area on Tuesday.  Temps slowly warm Wednesday and
Thursday before another Pac front sweeps through early Fri knocking
highs back into the 50s for the weekend.  Lows will generally be in
the 30s and 40s.

Rain chances start Wednesday night ahead of the next upper trough
and continue through Friday.  Have another shot of rain starting
Sunday night with the third upper trough this week.  Currently
this last trough looks to have the best chance of being a rain
producer but it is a long ways out and that could change.
