from the previous fcst pckg remain plausible at this time. Updated

For the 18Z TAFs, southwest surface winds will increase and become
gusty at times this afternoon through tonight as a sfc trof of low
pressure develops along the ern slopes of CO and NM in advance of a
cold front. This cold front is then slated to move across the region
Sunday morning. Periods of high level clouds are also anticipated

AVIATION...
Potential exists for a brief bout of MVFR stratus and BR this
morning, primarily at GUY.  Otherwise, VFR conditions expected to
prevail next 24 hours with only high-level clouds overhead.  Deepening
lee trof over eastern New Mexico today will support southwest surface
winds gusting into the 25 to 30 kt range this afternoon.  Surface
winds expected to remain up this evening, with occasional gusts as
shortwave trof approaches.  If surface winds do decouple this
evening, threat for low-level wind shear will exist after 04z Sunday.

PREV DISCUSSION... /Issued 359 AM CST Sat Dec 10 2016/

DISCUSSION...
Downsloping flow, southern flow at the surface, and sunny skies will
help the Panhandles to see temperatures increase to around 15
degrees warmer than yesterday. These will be the warmest temps of the
next 7 days. A cold front will drop temps slightly on Sunday as
northerly winds make a brief return for the day in conjunction with
a weak upper level trough and surface low. As high pressure moves in
for the beginning of the work week, temps will hover around
climatological norms. Another front will affect the area by mid week,
but with little moisture to work with, the passage will remain dry.
The upper level pattern looks to begin changing by the end of the
work week as a low pressure system comes on shore and digs into the
western Conus. Looking ahead to the weekend, while models differ
quite a bit, precip looks to make a return along with single digit
temperatures.
