.DISCUSSION...
Issued at 1127 AM MDT Sun Aug 24 2025

Mainly dry conditions persist for the next couple days across the
region as the upper high shifts to the southeast into Texas. The
best moisture will remain over northern areas closer to the high
this afternoon, allowing for isolated showers and storms, favoring
the Gila Region. Any convection that develops today will be weak
with only minor impacts, including gusty outflow winds. For the
lowlands, dry/continental air continues to filter in from the E-SE,
allowing for few-scattered CU and near-zero rain chances. Monday
looks very similar as the upper high elongates to the southeast into
the Gulf. Most of the area remains under the influence of the tongue
of the relatively dry air with spotty activity in the mtns for the
afternoon.

On Tuesday, the high centers itself over W TX, allowing a
subtropical moisture tap to shift eastward out of Sonora/Arizona.
The "dry tongue" will be overcome by the monsoonal plume Tuesday
night with PWs climbing to 10-30% above normal by Wed AM. Storm
chances will be favored in the higher terrain and west of the Divide
for the afternoon, then spreading eastward overnight with a low
threat of heavy rainfall and flash flooding. Storm coverage is
uncertain for Tuesday night depending on if a vort max/embedded
shortwave passes through the region from south to north. Winds
will be breezier from the southeast (10-15 mph) on Tuesday due to
the orientation of the ridge.

Wednesday`s storm chances will also be dependent on what happens
Tuesday night with potential for cloudy skies much of the day and
less instability for daytime convection to feast upon. Regardless,
if storms develop on Wednesday, there remains a threat of heavy
rainfall due to moisture levels staying above average and slow storm
motions with the upper high just to the east.

After Wednesday, there is some uncertainty regarding how much
moisture hangs around. The global ensembles generally have the upper
high in the west-central TX vicinity for the rest of the week with a
decent moisture tap continuing from the S-SW. Some ensemble members
indicate drier, westerly flow poking in on the northern side of the
ridge which would lower storm chances, especially for western areas.
The most likely scenario seems to be typical monsoonal activity late
in the week (scattered mtn/isolated lowland storms) after a more
active period around midweek. Temperatures will be near or slightly
below normal through the week.

.AVIATION...
(18Z TAFS)
Issued at 1127 AM MDT Sun Aug 24 2025

VFR conditions prevail through the forecast period. Other than
occasional gusts to mid teens this afternoon, winds will be AOB 8kts
from S-SE. Mid-high clouds linger through the afternoon in northern
areas with near-zero rain chances for KTCS into the evening. Mostly
SKC otherwise through tomorrow morning.

&&

.FIRE WEATHER...
Issued at 1127 AM MDT Sun Aug 24 2025

Fire weather concerns will be low through the forecast period.
Mainly dry through Monday with only a low chance of showers and
storms in area mountains. Gusty outflow winds are possible with a
low threat of dry lightning due to relatively dry lower levels.
Near-zero chance of rain elsewhere until Tuesday when moisture
increases from the south and west overnight. Above-average
moisture will result in better storm chances from Tuesday night
onward with a low risk of flash flooding due to slow storm
motions. Overnight recoveries will be fair to good through Monday
night, then very good to excellent for the rest of the week. Winds
become modestly breezy from the southeast on Tuesday (10-15 mph),
otherwise prevailing winds will be light. Temperatures remain near
or slightly below normal through the week.

Min RHs will be 15-25% through Monday, then 20-35%. Vent rates
range from poor to good through Monday, then good to excellent
Tuesday.
