.DISCUSSION...
Issued at 1150 AM MDT Mon Jun 30 2025

A push of easterly winds this morning has brought dew points back
up into the l/m 60s out east with areas toward the AZ border
getting to around 50. Some weak disturbances moving around Four
Corners high will trigger typical mountain storms by early
afternoon and storms pushing SSW into the evening. Gusty winds and
locally heavy rain will be the main threats. There is also an
inverted trough sitting through Hudspeth county and into the TX
Panhandle. This feature will be the focus for precipitation going
into tonight and into Wed. The inverted trough will be slowly
moving westward and provide the lift for showers and thunderstorms
to develop. HRRR even has a nice round of storms moving through TX
counties after midnight then another round around midday Tuesday.
I like the Tue depiction of activity with the HRRR given the
pattern. Wind profiles with 10-20KT easterly flow through about
H70 then weak winds aloft can lead to locally heavy rain and
flooding, but the question out east is will morning cloud cover
limit instability and bring just a more light to moderate
stratiform rain. For that reason, after collaborating with
neighbors, will hold off on a Flood Watch for now. Temperatures
Tuesday will range from the mid to upper 70s out east to near 90
out west.

The trough continues to move west into Wednesday. The GFS is now
washing it out by 18Z while the EC continues to hold onto this
feature centered right near the RGV. Either way, there will be
some lift around and with PW's getting into the 1.1"-1.6" range
and a continued favorable wind profile, there will be another
round of precipitation, more likely areawide. May need a watch for
Wed if everything comes together. As we progress into Thu, the
inverted trough does get washed out as a Pacific trough similar to
last week approaches. This, combined with the lingering moisture,
will bring another good chance for precipitation areawide with
drier air pushing in by late in the day out west. Did raise PoPs
with the upper trough pushing through. Even a little shear
developing into the afternoon as the WSW flow aloft moves in.
Instability not great, but maybe we can get a couple severe
storms.

Drier air will be in place for Fri-Sat and temperatures warm back
up into the mid 90s to around 100 for the lowlands. Models hinting
at just enough moisture around the far SW and SE edges of the CWA
for a storm or two, but will remain isolated in coverage. Upper
high becomes fairly well established over northern NM on all the
models, but the low level flow will once again tap Gulf moisture
from the southeast and bring a return to some thunderstorm
chances.

.AVIATION...
(00Z TAFS)
Issued at 539 PM MDT Mon Jun 30 2025

An active monsoon pattern will persist across the region tonight
and into tomorrow. The primary concern for aviation will be
scattered to numerous thunderstorms developing over the high
terrain and propagating into the adjacent lowlands. These storms
will be capable of producing strong and erratic outflow winds in
excess of 40 knots, which could lead to significant blowing dust
and visibility reductions, particularly at KDMN. Heavy rainfall
within these storms also poses a flash flooding risk, especially
over burn scars in New Mexico. For the terminals, the main
thunderstorm threat will be in the late afternoon and evening
hours (00Z-06Z). At KELP and KLRU, thunderstorms are expected in
the vicinity, while KTCS and KDMN have a higher probability of
direct impacts with associated MVFR to IFR conditions. Overnight,
low-level moisture will increase, leading to the development of
lower cloud decks, generally in the BKN080-BKN120 range,
especially east of the Rio Grande Valley. Winds will generally
remain from an easterly to southeasterly direction, becoming
lighter after the convective period.

.FIRE WEATHER...
Issued at 1150 AM MDT Mon Jun 30 2025

Moisture will remain in place through Thursday with a daily chance
for showers and thunderstorms. Some areas will see some locally
heavy rain. Temperatures will be below normal during this time as
well. Drier west to northwest flow will move in for Fri-Sun with
isolated thunderstorm coverage at best over far southern areas.
Temperatures over the lowlands will get back into the mid 90s to
around 100 dropping RH's into the mid teens and 20s.
