 - Mostly dry for the lowlands through midweek with storm chances
   favoring area mountains and west of the Divide. Storms will be
   capable of gusty outflow winds and localized flooding.

 - Temperatures will remain above normal with lowland highs in
   the mid to upper 90s.

.DISCUSSION...
Issued at 1031 AM MDT Sun Sep 6 2026

High pressure aloft over the Southern Plains early this week will
keep storm coverage limited even though moisture levels remain above
normal. PWs around 1.2" are modeled, which would allow for higher
rain rates and isolated flash flooding. However, the warmer air
aloft from the ridge will lower the convective potential each day.
Through midweek, synoptic models are not showing any noticeable
features such as shortwaves/vort maxes that provide additional
forcing to the typical orographic lift. We`ll have sufficient
moisture and instability each afternoon for convection to develop,
but are lacking a trigger for much of the week.

For today, the better moisture will be focused out west (as shown
by current WV imagery) with drier conditions along and E of the
RGV. There is a marginal risk of flash flooding W of the Divide
later today with rainfall over 1" possible in spots. Spotty
showers and storms are forecast for the rest of the lowlands with
convection favored over the west slopes of the Sacs this
afternoon. Outflow gusts to 30 mph are possible today.

The ridge axis remains extended through NM for Mon with slightly
lower rain chances area-wide, still favoring out west underneath the
moisture plume. Mainly dry conditions are forecast for the lowlands
on Mon. The high elongates across the southern US into midweek due
to a passing upper trough across the Midwest. Again, forcing will be
hard to come by due to the warmer air aloft and general subsidence.
Limited storm chances through Thu with better coverage out west. The
upper high re-establishes over the Desert SW late in the week as
moisture is recycled from the north around it. This may be the
beginning of the end of the monsoon as the westerlies dig further
south from the Rockies. The trough that squashes the high around
midweek may slip in from the N on Thu and bring some moisture and a
weak cold front, depending on where the upper high sets up.

A more significant feature to watch for is a deep upper trough
diving down the Rockies about a week from now, which the GEFS is
much more bullish on compared to the Euro ensemble. If the GEFS is
right, below-normal temps and breezy E/N winds would reach the
Borderland early next week. A wave of moisture and showers/storms
could also accompany this front from the Plains.

Temperatures will be near or slightly above normal (about 5
degrees) through the week with lowland highs in the mid-upper 90s.
El Paso may approach 100F late in the week as the upper high
consolidates to the west.

.AVIATION...
(00Z TAFS)
Issued at 539 PM MDT Sun Sep 6 2026

Showers and storms are still ongoing this evening but quite a lot
of the activity has diminished and fizzled out into showers.
Storms are starting to pop up near KDMN and west. Expect this
activity to continue through around 06Z but should fizzle away
after that. Light winds outside of any outflows.

&&

.FIRE WEATHER...
Issued at 1031 AM MDT Sun Sep 6 2026

Fire weather concerns will be low through the week. Storm chances
will be limited through midweek as an upper ridge sits nearby.
Mostly dry conditions are forecast E of the Divide today, with the
exception of scattered activity over the Lincoln. Better coverage is
expected out west today with a marginal risk of heavy rainfall.
Overnight RH recoveries will be very good to excellent tonight.
Light SE flow today outside of outflows gusting up to 30 mph,
continuing into midweek. Slightly lower rain chances area-wide for
Mon, again favoring N and W. Temperatures will be seasonably warm
this week as moisture levels remain near or above normal.

Min RHs range from 20-30% in the lowlands through midweek, 30-50% in
the mtns. Vent rates will be poor to good through midweek.
