.DISCUSSION...
Issued at 1116 AM MDT Sun Jul 27 2025

Looks like an uptick in thunderstorm activity across the area
starting this afternoon, maxing out Mon/Tue then a gradual
decrease towards the end of the week. This is due to an inverted
trough approaching from the east which will slowly move toward the
AZ/NM border region by midweek. All models depict this scenario,
but do differ on the timing. The EC is slower than the GFS and
each ensemble mean supports it's deterministic run. Through this
evening, we will see some development by mid afternoon along and
east of the Rio Grande where isolated to low end scattered
coverage is likely. As outflows move west, would not be surprised
to see isolated activity out towards the Continental Divide before
dying after sunset. Moisture really increases along this inverted
trough with PW's up to 1.4-1.5" out west by Tue. All areas Mon and
Tue will see thunderstorms each afternoon and continuing through
the night, mainly west of the Divide where the trough stalls out.
There is some concern for some flash flooding out west with this
kind of moisture in place and a stationary feature. 95th
percentiles out west for QPF is upwards of 1.25-1.5" and this may
be low, would not be surprised to see areas well over 2" Mon/Tue.
There is still a little uncertainty with how far west it moves,
but may need a Flood Watch out west for later Monday and Tue at
least along the AZ border. Temperatures will be cooling down with
this increase in moisture and most areas will remain in the lower
to mid 90s, could even stay in the M/U 80s out west where cloud
cover may linger through the day.

Going into the end of the week, the upper high that will bring
very hot temperatures to the Southern Plains will be retrograding
west into the Borderland. This pushes moisture plume mainly into
AZ with just some areas along the AZ border keeping a chance for
afternoon/evening thunderstorms. Temperatures will start warming,
especially out east back to 100+ degrees.

By the weekend, the upper high elongates across most of the
southern US with some mid level moisture moving around and back
into the area from the west and north. Surface dew points don't
get much above the 50 degree mark and any storms that develop will
be high based and likely be more of a wind than rain producer.

.AVIATION...
(00Z TAFS)
Issued at 528 PM MDT Sun Jul 27 2025

ISO to SCT SHRA/TSRA are ongoing across the area though mainly
east of the Rio Grande. VCTS is noted for LRU and ELP. Convection
is expected to gradually decrease/clear terminals by 02z. +TSRA
and gusty winds will be the main impacts. There is no mention of
the thunder for TCS or DMN, but it cannot be ruled out. After 2z,
convection should wane, but more TSRA/SHRA are expected for
tomorrow during the late afternoon and evening hours.

Winds will mainly be light with speeds under 10 knots along with a
few gusts to 20 knots except where impacted by storm outflows.
Direction will favor the East (070-120) at most sites. Skies will
be variable with bases as low as 100.

.FIRE WEATHER...
Issued at 1116 AM MDT Sun Jul 27 2025

Moisture is returning to the area with thunderstorm activity
starting mainly east of the RGV through this evening then
spreading areawide for Mon/Tue. Some areas, especially west of the
Continental Divide may see some heavy rain and flooding early this
week. RH's will fall into the 20s/30s through midweek before drier
air moves into the east with high temperatures returning to 100+.
Min RH's even with this drier air look to remain in the mid to
upper teens. Rain chances will continue at least along the AZ
border and Gila region through the work week. Winds will generally
be light except near thunderstorms.
