.DISCUSSION...
Issued at 958 AM MDT Tue Jul 28 2026

Today will see the best (worst?) of both worlds as very hot
temperatures expand across the RGV/eastward and monsoonal moisture
sets up out west. The upper high sits over E NM today, allowing
lowland temps to climb to about 105 and warranting Heat
Advisories. Moisture rotates around the western periphery of the
high, bringing isolated to scattered storm chances out west this
afternoon and evening. Slow storm motions to the northwest and
PWs around 1.2" will result in flash flood potential west of the
Divide. HREF max 6-hr rainfall shows up to 2" of rain with
consistent bulls-eyes in the NM Bootheel this evening. Somewhat
lower amounts are forecast in the Gila this afternoon before
focusing further south. With saturated soils from recent rainfall
and this heavy rain potential, Flood Watches have been posted.
Mainly dry conditions are expected from Deming eastward.

The upper high doesn`t move much through Thu, flattening out a bit
due to a shortwave passing through the Central Rockies. Moisture
levels decrease somewhat out west through midweek with lower storm
chances than today. Temps stay above normal through the workweek
with more Heat Advisories likely, especially on Fri as the high
stretches west.

Heading into the weekend, the high parks itself over AZ, allowing
moisture and shortwaves to rotate in from the north. Scattered
mtn storms are modeled each afternoon, drifting to the south and
west with more isolated coverage in the lowlands. Gusty outflows
and blowing dust are possible for the lowlands. Better moisture
and storm chances will slightly lower highs towards 100 for the
lowlands.

.AVIATION...
(18Z TAFS)
Issued at 958 AM MDT Tue Jul 28 2026

Low storm chances W of KDMN this afternoon and evening with dry
conditions expected for all terminals. Gusty outflows over 30kts
possible in the evening from W-NW, favoring KDMN and KTCS. BLDU
may reduce VIS to 3 SM at KDMN from outflow. Winds AOB 10kts
outside of outflows, favoring S-SE direction.

&&

.FIRE WEATHER...
Issued at 958 AM MDT Tue Jul 28 2026

Fire weather concerns will be low through the forecast period.
Isolated to scattered storms develop out west this afternoon with
some heavy rain/flash flood potential. Frequent lightning and
outflow gusts to 40 mph are possible into the evening. Most areas
remain dry today with light S-SE winds and temps above normal.
Storm chances decrease Wed/Thu to the west as temps remain hot.
Area mtns will see better storm chances into the weekend with
spotty coverage in the lowlands. Temps cool off slightly for the
weekend. Winds remain light from the southeast this week.

Min RHs range from 12-30% through Fri. Vent rates will be good to
very good.
