.DISCUSSION...
Issued at 1016 PM MDT Sun May 10 2026

Gusty east winds will continue into the overnight along the I-10
corridor behind the outflow-enhanced backdoor cold front. West mtn
slopes will see the strongest gusts to 40 mph through midnight,
subsiding Mon AM as the pressure gradient loosens. The breezy winds
shift west during the AM towards AZ. With favorable radiational
cooling and some lingering moisture tonight, low stratus/fog looks
to develop in the early AM in the Sacs, mixing out during the
day. Other than scattered CU over area mtns in the afternoon,
clear skies are expected on Mon.

An upper ridge sits over NM into Wed, keeping rain/storm chances
near zero. Scattered convection over the Sierra Madres could shoot
some outflow boundaries our way in the evening hours with
possible dust. An isolated shower cannot be ruled out for the
mountains and out west each afternoon if the subsidence capping
can be overcome.

The high breaks down Wed/Thu as a Pacific storm system reaches the
West Coast. Some moisture is lifted northward by a shortwave
trough on Thu ahead of the system, bringing clouds and a slight
chance of showers. Most likely, the main low passes well to the
north Thu/Fri with some breeziness and dry weather for us. A less
likely scenario is the low takes a more southerly track with
stronger west winds to end the workweek. Light SW flow aloft is
modeled for next weekend as a dryline tries to develop to the E.

A slight cooldown for Mon due to modest cold air advection behind
tonight`s front. Warmest temps are forecast Tue/Wed underneath the
ridge with lowland highs well into the 90s. KELP may approach 100
for the first time this year on Wed. We remain very warm through
the weekend.

.AVIATION...
(06Z TAFS)
Issued at 1016 PM MDT Sun May 10 2026

Skies clear tonight with low clouds/fog developing over the
Sacramento Mtns. Scattered CU develop over area mountains Mon
afternoon, otherwise SKC during the day. Backdoor front brings
breezy E winds (gusts to 20-25kts) early in the period outside of
KTCS, subsiding by the AM. Winds shift SE during the day.

.FIRE WEATHER...
Issued at 1049 AM MDT Sun May 10 2026

Today and this evening, a frontal boundary is pushing N and W
across the region, with breezy and gusty northeast winds. This
front does have some moisture moving in behind it, with increases
in dewpoints. This will add moisture to areas generally east of
the Rio Grande, and spilling into Sierra County. This afternoon
and evening, this could mean scattered showers and thunderstorms
over the SACs, and more isolated storms over the lowlands of Otero
county, and northern Hudspeth counties. There also can`t be ruled
out a stray storm over eastern Sierra and Dona Ana counties.
Otherwise, for most of the region, another dry day. The region
remain on the front side of a ridge parked over the SW U.S. This
means low grade warming across the region, with temperatures a bit
above normal. It also means no strong winds events. Over time
this week, the upper ridge to our west will slowly translate east,
and settle directly over the area by WED. This will mean a
continued trend toward warming and drying. Both Min RHs and RH
recovery will suffer, as we see values trend downward, with daily
low RH near single-digits. Thus fire weather conditions will move
toward Elevated, but due to the high pressure, winds will not be
on the increase. Thus, without strong winds, we will avoid a
Critical fire weather pattern this week, despite the warm and dry
conditions.
