30-35kts will be possible at MAF/HOB/INK causing some low level
turbulence. Winds will be strongest 15-18Z then diminish 18-00Z

Currently, a cold front has moved through southeastern New Mexico
and is located along a line from Guadalupe Pass to McCamey and
Big Lake. Winds behind the front are shifting from the northwest
to northeast and will remain modest through around 12Z before
increasing later this morning. Surface pressure rises of 10-15mb
will support sustained surface wind speeds of 20-35 mph. There
will also be a brief period of time when 850mb winds of 35-45 mph
will mix to the surface creating borderline Wind Advisory
conditions. Decided to hold off issuing an advisory due to the
marginal nature of the wind event but he day shift will need to
monitor this. It will not be marginal at KGDP where strong
northeast gap winds are expected and the warning will continue for
the passes of the Guadalupe Mountains.
Yesterday was almost certainly our last hundred degree day of the
year here at MAF with this cold front bringing in temperatures that
will struggle this afternoon to reach 80 degrees in most locations
north of I-10. Tonight will be crisp with lows into the 50s and even
a few upper 40s in portions of the area near Seminole, Hobbs, and
Tatum. These cool overnight lows will hold temperatures down again
Wednesday with highs similar to today. A few light showers currently
in the Big Bend/lower Trans Pecos will move southeast later today
and not produce any meaningful rainfall amounts.

(Wednesday night through Monday)
Issued at 300 AM CDT Tue Sep 21 2021
Our brief cool down will come to an end on Thursday as high
temperatures return to a few degrees above normal. Highs should
remain near or slightly above normal through much of the extended
portion of the forecast and lows will increase slightly from Friday
morning into this weekend. Ridging aloft will build over the
forecast region Thursday and Friday as a trough deepens over the
Intermountain West. Models now depict this trough pinching off and
becoming a closed low over southern California late this week into
this weekend. Unfortunately, this feature looks to remain too far
west to influence weather here in West TX and southeast NM. The
exception being the GFS which brings this closed low over the
forecast region early next week along with better precipitation
chances. For now, will maintain a dry forecast until models can
come into better agreement.
