.DISCUSSION...
Issued at 1100 PM MDT Wed Sep 2 2026

It is looking more and more likely that we have seen the last of
the triple digit heat for this year. As we move further into
September it gets harder and harder to hit 100F. Case and point,
Thursday`s record high temperature is only 101F. Now we may be
finished with the triple digit heat, but that does not mean any
great cool down. High temperatures will continue to run several
degrees above average into the start of next week. Which means
lowland high temperatures will be in the mid to upper 90`s through
the weekend.

Another factor helping to shave a few degrees of our high
temperatures will be the increase in moisture. Precipitable water
values (PW`s) will continue to run in the range of 1.2 to 1.3
through next Tuesday. This will be enough moisture to help fuel
scattered mountain and isolated lowland thunderstorms each day
through the weekend and into the start of next week. We won`t see
rain all over the place each afternoon, but we should see a little
better rain coverage than we have seen the last few days. Looking
just beyond the forecast period there are some significant
differences in the rain chances. The GFS parks our old friend the
upper level ridge over the southeast U.S. which allows copious
amounts of moisture and rain chances to move into the region from
northern Mexico for the middle and end of next week. But the ECMWF
keeps a lobe of the upper level ridge leaning into New Mexico and
that really limits any moisture influx getting into the area.
Considering how our summer has been going, I`m tending to learn
more toward the drier solution.

.AVIATION...
(12Z TAFS)
Issued at 530 AM MDT Thu Sep 3 2026

Skies FEW-SCT120 this morning with spotty -SHRA along the Intl
Border. Surface winds generally 210-240 AOB 6 knots this morning,
then 230-260 at 5 to 10 knots mid-afternoon. Isolated TSRA
developing after 18Z, with SCT-BKN100 skies and VCTS around TAF
sites after 21Z. Gusty surface winds and possible BLDU moving
north out of Chihuahua after 01Z tonight due to TS outflows.
Gusts up to 40KT possible. Scattered TSRA may linger overnight
into early Friday morning.

.FIRE WEATHER...
Issued at 530 AM MDT Thu Sep 3 2026

Isolated showers and thunderstorms over NM forests this afternoon,
which could cause sudden, erratic wind gusts. Localized flooding
is also possible. Min RH 25-35% with good overnight recoveries.
Southwest winds 5 to 10 mph leading to Fair/Good vent rates. Rain
showers may linger later than usual tonight, into early Friday
morning for much of southern NM.

Good rain chances for both Lincoln and Gila NF over the weekend,
with flooding risk peaking during the mid-afternoon hours each
day. This extended period of favorable rain chances will keep fire
danger low with minimal risk of new lightning starts. Prevailing
flow shifts out of the SE Sunday into next week, with midday vent
rates generally Poor/Fair.
