Hot with highs in the mid to upper nineties west of the Plateau this week. Major to extreme heat risk this week with heat index values in the triple digits. Wednesday and Thursday are anticipated to be the hottest days of the week. Very low rain chances through midweek. The sky hardens into an impenetrable shield of oppressive air The ridge anchors itself directly over our hollowed ground No shadow will save us from the impending doom SWALLOWED BY THE INFLEXIBLE RIDGE OF HIGH PRESSURE! DEW POINTS IN THE SEVENTIES CONSUME THE DYING ATMOSPHERE! Highs pushing relentlessly into the mid to upper nineties across the western plateaus A forty percent chance of exceeding one hundred degrees as the oppressive dome locks down Afternoon heat index values climbing violently to one hundred nine on Wednesday and Thursday Overnight lows offer no sanctuary as temperatures hover helplessly in the seventies Near zero rain chances leaving only barren cumulus clouds to mock our desperate search for shade The horizon burns with an unyielding golden doom The heavy moisture traps the torment of the afternoon We bleed beneath the cruel weight of this endless sky We arrive at the peak of the heat Atmospheric stagnation locks the sun overhead A relentless pressure field that refuses to yield Late in the week an upper level troff begins its slow march into the Northeast The ancient ridge reluctantly yields ground as forcing remains hopelessly weak Gradual cooldown brings no salvation as highs remain fixed in the low to mid nineties Rain chances linger on the distant horizon like a forgotten promise of survival ONE HUNDRED NINE DEGREES! NO ESCAPE FROM THE DOME! THE RIDGE UNFAILS! STAGNATION IS OUR GRAVE!

SHORT TERM
(Tonight through Wednesday Night) Issued at 1049 PM CDT Mon Aug 31 2026
The upper level ridge is starting to build over the eastern half of the US and that will bring a prolonged period of hot weather.
Highs are already well into the 90s and we will see that continue this week as the ridge remains overhead.
Wednesday and Thursday look to be the peak of the heat with highs pushing into the mid to upper 90s and up to a 40% chance of 100+ for parts of the area.
Once you add in humidity with dew points in the 70s we will see afternoon heat index values push into the triple digits and will be as hot as 109 Wednesday and Thursday.
This heat will bring major to extreme heat risk by the middle of the week.
Overnight lows are also going to remain mild only falling into the 70s.
With the ridge overhead rain chances will be near zero but afternoon cumulus clouds can be expected.
LONG TERM
(Thursday through next Tuesday) Issued at 1049 PM CDT Mon Aug 31 2026
The upper level ridge will start to break down and build west late week as an upper level trough pushes into the Northeast.
This will start to bring a gradual cooldown Friday into the weekend.
It will still be on the hot side over the holiday weekend but highs should fall back into the low to mid 90s.
Highs will continue to cool into early next week into the upper 80s to lower 90s which is getting a little closer to seasonal norms.
As the ridge breaks down rain chances will increase but overall forcing will be weak keeping the chances low to medium mainly during the afternoons.
