.SHORT TERM...
(This afternoon through Saturday night)
Issued at 132 PM CDT Fri Sep 11 2026

WV imagery this afternoon shows an upper trough moving through the
MS Valley, infringing upon what would otherwise be a broad ridge
spanning the southern CONUS and areas south.  However, said trough
is not making a dent locally in temperatures, w/this afternoon`s
highs looking to top out ~ 12-14 F above climatology.  The KMAF 12Z
RAOB came in w/a PWAT of 1.63", which is around the 99th percentile.
Unfortunately, other than residual boundaries from yesterday`s
convection, no triggers are evident to tap into this wasted
moisture, other than orographic activity this afternoon invof
the Davis Mountains.

Tonight, a strong LLJ of 40 kts is forecast to develop, and this
will keep the boundary layer well-mixed.  This will combine with a
thin veil of high cloud to retard radiational cooling, resulting in
perhaps the warmest night this forecast as minimums stall at almost
15 F above normal.

Tonight`s warm lows will provide a head start to highs on Saturday,
when thicknesses increase slightly over this afternoon, yielding the
warmest day this forecast, and maybe even for the rest of the year,
as highs top out an average of over 15 F above normal.  W/this in
mind, the upper Colorado River Valley looks to warrant a Heat
Advisory.  Areas to the west are on the fence, and we`ll let the mid
shift make the call on those.  Isolated afternoon convection is
possible invof the Davis Mountains.

Saturday night, the LLJ isn`t forecast to redevelop quite as strong
as tonight, and lows will be similar, but slightly cooler, than
tonight.

.LONG TERM...
(Sunday through Thursday)
Issued at 132 PM CDT Fri Sep 11 2026

The forecast remains unchanged from the previous package. Warmer
than normal temperatures for mid September standards continue
through next week. Sunday through Tuesday, high temperatures are
forecast to persist in the mid 90s to lower 100s for most spots.
This is thanks to upper-level ridging staying over the region. By
Tuesday, the upper-level ridge shifts eastward due to upper-level
troughing west and north of the region. As a result, temperatures
begin a downward "cooling" trend beginning Tuesday lasting through
the rest of the week. Highs will cool a few degrees where most
locations span in the low to mid 90s. Rain and storm chances (20-
50%) increase west of the Pecos River and across southeast New
Mexico for much of the work week. Diurnal heating, combined with
surface troughing and shortwaves rounding the periphery of the ridge
will provide the necessary ascent each afternoon and early evening.

(00Z TAFS)
Issued at 629 PM CDT Fri Sep 11 2026

VFR conditions will remain prevalent through Saturday afternoon
with mainly S/SE winds (except becoming light westerly to
northerly late tonight into early Saturday morning at CNM and
INK). Isolated afternoon and early evening convection should
remain confined to the higher terrain west of the local
terminals.
