...New SYNOPSIS, DISCUSSION, FIRE WEATHER...

.SYNOPSIS...
Issued at 254 AM MDT Wed Jul 3 2024

Rain chances will begin to slowly decrease over the next few days
as slightly drier air moves in from the northwest. By this
weekend, temperatures will be warm, running a few degrees above
the seasonal average with daily isolated to scattered showers and
thunderstorms each day.

.DISCUSSION...
Issued at 254 AM MDT Wed Jul 3 2024

High pressure aloft over the Deep South and Southern Mississippi
River Valley, along with a strengthening upper level high off the
coast of California will be the synoptic scale features driving the
weather locally across the Desert SW through the weekend.

The deep Monsoonal moisture that`s been giving active weather over
the past several days will remain over the Borderland Region on
Wednesday. Both GFS/ECMWF deterministic models and the respected
ensemble suites continue to show deep moisture across the local area
with PW values between 1.2-1.5" and surface dewpoint temps in the
low 60s. However, high-res model guidance isn`t too excited with the
prospects of seeing scattered to numerous showers and storms this
afternoon and evening. Cloud coverage from yesterday evening`s
activity will likely stick around through the morning and into the
afternoon hours across most of the area. Ultimately keeping
thermodynamic conditions stable with less sun and slightly cooler
temperatures. RAP analysis forecast soundings show convective
temperatures in the middle to upper 90s during the afternoon, as of
now with the expected cloud cover, temperatures look to fall
short of the Convective temps. That said, isolated to scattered
showers and storms will be possible across the area, especially if
we can see some sunshine. The area of focus will be over the Gila
region and areas west of the Divide.

On Thursday, the strengthening high pressure aforementioned above
will move onshore across western CONUS with it`s eastern
periphery nosing into the Four Corners vicinity.
North/northwesterly flow will increase as a result, pushing the
deep Monsoonal moisture slowly towards the south and southeast.
This dry influence along with increasing 500mb heights will
decrease rain chances across the northern portions of the CWA with
the focus for isolated to low-end scattered showers and storms
across West Texas and along the International Border. Isolated
storms will be possible over the Gila and Sacs due to orographics.
Temperatures on Thursday will warm above 100 degrees.

For Friday and into the weekend, daily afternoon and evening
isolated to scattered showers/storms will be possible. Temperatures
each afternoon will hover right around the 100 degree mark with
light winds.

.AVIATION...
(06Z TAFS)
Issued at 1127 PM MDT Tue Jul 2 2024

Lingering showers and thunderstorms remain over the area tonight.
This activity is expected to continue and gradually diminish
through the early morning hours. Showers will be mainly light in
intensity with brief periods of moderate rainfall that might briefly
reduce visibility to near MVFR categories at local TAF sites.
Ceilings will remain at or above 10 kft becoming lifting higher to
above 15 kft by 14Z.  Winds will mainly west northwest at 10 to
15kts becoming lighter after 12Z.  Thunderstorm activity is expected
to be more isolated Wednesday afternoon.

.FIRE WEATHER...
Issued at 254 AM MDT Wed Jul 3 2024

Fire weather concerns are LOW on Wednesday. Isolated to scattered
showers and thunderstorms will be possible during the afternoon and
evening. Min RH values will be greater than 25 percent areawide, 30-
50 percent over the mountains. Temperatures will be a few degrees
cooler than yesterday with partly to mostly cloudy skies. The
possibility for new lightning starts are low due to higher soil
moisture within the mountains and forested regions. Winds will be
light under weak west/northwest flow.

Slightly drier conditions expected on Thursday through the weekend
as drier air noses in from the northwest. Min RH values become
critically low over the Gila Region and NMZ112 on Thursday. Daytime
winds will remain light, predominately diurnal and terrain
influenced. Vent rates will range from Fair to Good today and
Thursday, becoming Good to Very Good this weekend.
