.SHORT TERM...
(Today and tonight)
Issued at 1239 AM CDT Sun Aug 23 2026

Showers and a few thunderstorms continue to our east, but are also
winding down late tonight. Expect this trend of diminishing
coverage and intensity to continue through the rest of the early
morning hours. For today, we will again warm up into the 105 to
110 degree range across areas roughly north of a Mertzon to 
Junction line, with upper 90s to near 105 for the rest of the
area. With that in mind, the Heat Advisory in these areas will 
continue through tomorrow evening. Although we will approach the 
110+ degree mark that warrants in an Extreme Heat Warning north of
I-20, we aren't expecting to quite make it there, so will just 
keep the Heat Advisory going. Lows will continue to be very muggy,
only dropping into the mid 70s to lower 80s, and winds will be out
of the south at 5 to 15 mph.

.LONG TERM...
(Monday through Saturday)
Issued at 1239 AM CDT Sun Aug 23 2026

Expect hot and dry conditions across the area as a upper level 
ridge remains in control. Looks like will need Heat Advisories for
much of next week across much of the area. Please follow heat 
safety precautions if you have to be outside during the afternoon 
hours. Highs will mainly range from the upper 90s to near 110, 
mainly across the Big Country, expecting to have the hottest 
temperatures. Also, mostly sunny skies will make it feel even 
hotter. There is a very low chance for a few showers and 
thunderstorms by the middle of next week. However, most of the 
area will remain dry through the long term.
