.KEY MESSAGES...
Issued at 1244 PM CDT Thu Jul 23 2026

- Storm chances exist this afternoon/evening across the northern
combined Panhandles. Also, tomorrow mainly along and south of   HWY
60. Some storms may posed a severe potential for damaging   winds.

- Multiple days of triple digit temperatures are set to continue
through the 7 day forecast with very little relief in overnight
temperatures.

.UPDATE...
Issued at 712 PM CDT Thu Jul 23 2026

Outflow boundary collision with the retreating dryline is expected
to generate an increase in storms across areas from Beaver County
to NRN Lipscomb and Ochiltree Counties this evening. Did a quick
POP update to increase chances there to account for this
possibility a little better.

.SHORT TERM...
(This evening through Friday night)
Issued at 1244 PM CDT Thu Jul 23 2026

Hot temperatures continue today into tomorrow. Tonight a shortwave
trough may brush the northwest bringing some precip chances to the
northwestern combined Panhandle, mainly impacting the north to
northwestern Panhandles. Primarily in the OK this evening. The main
threat with the 30 to 60 PoPs across the far northern Panhandles
will be damaging winds and lightning.

Tomorrow, a weak surface low is progged to set up over the combined
Panhandles introducing a surface boundary along the HWY 60 corridor.
This will focus a 30 to 40 PoPs along and south of HWY 60. The
timing of the storms to initiate is currently around 4pm to 9 pm.
Wide spread severe storms are not anticipated, but cannot be
completely rule out for damaging winds and localized heavy rainfall.
The timing of storms could potentially impact afternoon highs,
holding back from their max potential. Still, heat advisories will
be looked at as temperatures may still very well reach 105 for some
locations, especially in the southeast where higher dewpoints may
keep heat indices up to near 105. Going into the evening some
lingering showers and thunderstorms may exist in the southeastern TX
Panhandle. However, should see things quiet down around midnight
with overnight lows slightly cooler but still in the 70s for the
southeast TX Panhandle.

.LONG TERM...
(Saturday through next Wednesday)
Issued at 1244 PM CDT Thu Jul 23 2026

High pressure will continue to dominate with high temperatures
reaching into the triple digits. Pretty much through the extended
period. The one caveat will be Saturday where some locations may be
held back near 99 for a high. This will be highly contingent on the
amount of rain that can be realized on Friday, as soil moisture
could locally hold back some isolated areas from full potential
heating. The extended period is looking dry outside of maybe
Cimarron getting clipped by some ridge riders. Each day will have to
be looked at closely for potential of may a 10 PoP at most, but it
is too far out to tell at this time for subtle details is moisture
and convective temperatures attempting to pop an isolated shower or
two.

.AVIATION...
(00Z TAFS)
Issued at 712 PM CDT Thu Jul 23 2026

VFR conditions will prevail outside high based showers and storms
in the area. The first round of sct storms is moving across the
region this evening with DHT and GUY having the greatest chance
for being impacted. A boundary will generate storms across the
southern Panhandles on Friday afternoon and evening with AMA
having the best chance for impacts during that timeframe. Included
PROB30s accordingly to account for this activity.
