.SYNOPSIS...
Issued at 200 PM MDT Mon Jul 1 2024

.DISCUSSION...
Issued at 200 PM MDT Mon Jul 1 2024

We are in a typical monsoonal pattern this afternoon. High
pressure is centered east of Dallas, with an east-west oriented
ridge axis extending from our CWA to AL. This has directed the
richer portion of the moist plume west of the Divide with some
drier air trying to move into Hudspeth and Otero Counties. Of
note, there is a well defined swirl near Pecos, TX. It seems its
only impact to the CWA is perhaps some subsidence to eastern
areas. Either way, thunderstorm coverage is expected to increase
throughout the afternoon with highest chances west of the Rio
Grande.

Beginning Tuesday, our portion of the ridge will begin to weaken,
allowing better moisture to move into NM and Far W. TX. The HRRR
shows an uptick in thunderstorm coverage, possibly picking up on
the fact there will be height falls ahead of an approaching UL
trough axis. By Wednesday the ridge will have completely opened up
for our area with one center off the Pacific Coast and the other
centered toward the Southeast. Wednesday is expected to be our
most active day with a passing trough axis, rich moisture, and
height falls. Flash flooding would be the main concern.

For Thursday and Friday, drier air will move in from the north and
northwest, greatly limiting thunderstorm chances. Temperatures
will climb for Thursday, but a side door/ back door front will cut
temperatures back down for Friday. This front will also allow
moisture to return increasing thunderstorm chances for late Friday
and especially Saturday. Drier air filters back in via NW flow
aloft on Sunday, once again lowering storm chances.

.AVIATION...
(06Z TAFS)
Issued at 1139 PM MDT Mon Jul 1 2024

Lingering showers and thunderstorms remain over the area tonight
but will continue to diminish through the overnight hours. Mid and
high level clouds expected to remain into the afternoon hours
with better coverage for KDMN and KTCS. Light winds overnight and
into the afternoon tomorrow, but another round of afternoon
monsoonal thunderstorms is expected, possibly with better coverage
than what we saw today. All TAFs sites have a chance to see a
thunderstorm tomorrow in the mid-afternoon hours. Gusty outflow
winds will be the primary hazard, but plentiful lightning and
small hail also possible with strong storms.

&&

.FIRE WEATHER...
Issued at 200 PM MDT Mon Jul 1 2024

No significant fire concerns anticipated for the period. Monsoonal
moisture continues in place with moisture anticipated to increase
for Wednesday. This will lead to at least scattered thunderstorms
with the best chances for precipitation in the mountains and west
of the Rio Grande, spreading across the entire area by Wednesday.
Min RH values will be in the 20s with recoveries into at least the
50s. Winds will be light outside of thunderstorm influences.
Venting will range good to very good for Tuesday, decreasing to
fair to good for Wednesday.
