.DISCUSSION...
Issued at 1022 AM MDT Sat Sep 5 2026
Above-normal moisture (PWs 1.2-1.4") remains for today with mid-
level clouds clearing out by the afternoon, similar to yesterday.
The ridge axis from the central Plains is still in place, resulting
in a bit of subsidence and limiting storm initiation. Storm chances
will be more favored E of the RGV this afternoon where there`s
better moisture/instability (SBCAPE 500-1000 J/kg). Slow storm
motions and high rain rates may result in isolated flash flooding,
most likely in the NW Sacs where the HREF has max rainfall up to 2".
Outflow gusts over 30 mph are possible today as the convection
dissipates in the evening.
The upper high moves a bit south on Sun over OK as forcing remains
limited. 90th %-ile PWs and the best storm chances shift N and W
tomorrow. Mostly dry conditions are expected along and E of the RGV
for Sun with isolated storm coverage, excluding the Sacs where
scattered storms are forecast. Similar conditions are forecast for
Mon with little change in the upper high`s placement and the
monsoonal moisture plume sitting over western areas.
The upper high stretches across the southern tier of the US through
midweek. The easterly flow underneath the high will nudge the
moisture plume further S and W, but PWs hold in the 1.1-1.2" range,
enough to give most of the lowlands at least a slight chance of
storms through Thu. The heavy rain threat should lower out west
after Mon. As an inverted trough approaches from the east around
midweek, the high is modeled to centralize over the Desert SW. This
feature would keep the trough south of our area late in the period,
but recycled moisture around the ridge keeps low-end storm chances
alive into next weekend.
Temperatures will be near or slightly above normal through the
period with lowland highs in the low-mid 90s. Relatively warm temps
are forecast for eastern areas this week.

.AVIATION...
(18Z TAFS)
Issued at 1022 AM MDT Sat Sep 5 2026
Scattered TS over area mtns to begin the period with isolated
convection this afternoon mainly E of RGV. 10-20% chance of TS for
KTCS and KELP into the evening, lower chances for KLRU and KDMN.
Outflow gusts to 30kts and brief downpours possible. Convection
dissipates this evening. Prevailing winds light and variable.
&&
.FIRE WEATHER...
Issued at 1022 AM MDT Sat Sep 5 2026
Fire weather concerns will be low through the middle of next week.
For today, scattered storms are forecast for the Lincoln Nat`l
Forest with isolated flash flooding this afternoon due to slow
storm motion and high rain rates. More isolated activity is
expected elsewhere, favoring eastern lowlands. Gusty and erratic
outflow winds to 30 mph are possible. Prevailing light and
variable winds expected. From Sun onward, storm chances and heavy
rainfall favor western areas with more isolated coverage
elsewhere. Moisture levels remain above normal for early Sep.
Winds stay light, shifting more E-SE this weekend. Temperatures
will be a few degrees above normal next week.
Min RHs range from 25-35% in the lowlands, 35-60% in the mtns.
Vent rates will be poor to good today, then mostly fair to good.
