UPDATED AT 632 AM CDT SAT JUL 25 2026
- EXCESSIVE HEAT TODAY WITH AN EXTREME RISK FOR HEAT RELATED

NEAR TERM
(THROUGH SATURDAY)
ISSUED AT 141 AM CDT SAT JUL 25 2026
CONTINUED HEAT HEADING INTO THIS WEEKEND WITH THE UPPER RIDGE
BUILDING OVER THE SOUTHERN ROCKIES. TEMPERATURES WILL RANGE FROM THE
UPPER 90S TO 105 DEGREES AND WITH CONTINUED LOW-LEVEL MOISTURE,
EXPECT WIDESPREAD HEAT INDICES OF AT LEAST 105 TO 110 DEGREES. AREAS
ACROSS NORTHERN INTO CENTRAL OKLAHOMA WILL HAVE HIGHER DEWPOINTS,
WHICH MAY GIVE WAY TO HEAT INDICES OF 110 TO 115 DEGREES. THEREFORE
AN EXTREME HEAT WARNING IS IN EFFECT FOR THE AFOREMENTIONED AREA
FROM 11 AM TO 9 PM TODAY. ELSEWHERE, A HEAT ADVISORY IS IN EFFECT
FOR THE SAME TIME FRAME. LIGHT WINDS COUPLED WITH HEAT AND HUMIDITY
WILL GIVE WAY TO A HIGH TO EXTREME HEAT RISK WITH TIME SPENT
OUTDOORS BEING LIMITED AND PLENTY OF HYDRATION NEEDED. SOME
AFTERNOON SHOWERS AND STORMS MAY ATTEMPT TO DEVELOP THIS AFTERNOON
ACROSS PORTIONS OF NORTHERN INTO CENTRAL OKLAHOMA, BUT ANY UPDRAFT
WILL BE FIGHTING SUBSIDENCE FROM THE UPPER RIDGE. HOWEVER, IF A
STORM DOES DEVELOP, DCAPE VALUES OF 2000+ J/KG COULD LEAD TO STRONG
TO DAMAGING WINDS WITH ANY DOWNDRAFTS FROM DECAYING STORMS. CHANCES
ARE VERY LOW, BUT THE GREATEST TIMEFRAME WOULD BE DURING THE
AFTERNOON AND EARLY EVENING HOURS DURING PEAK HEATING.
SHORT TERM
(SATURDAY NIGHT THROUGH MONDAY NIGHT)
ISSUED AT 141 AM CDT SAT JUL 25 2026
THE TREND OF VERY HOT TEMPERATURES CONTINUES SUNDAY AND MONDAY AS
THE UPPER RIDGE CONTINUES TO REMAIN NEARLY STATIONARY AND WIDESPREAD
TRIPLE DIGIT TEMPERATURES ARE EXPECTED BOTH DAYS. THE BIGGEST
DIFFERENCE WILL BE THAT SURFACE TROUGHING TO THE WEST MAY INTRODUCE
SOME DRIER AIR AND SCOUR SOME OF THE LOW-LEVEL MOISTURE THAT WAS
BRINGING THE HUMIDITY AND EXTREME HEAT RISK CONDITIONS. HOWEVER,
DESPITE SOME REDUCTION IN DEWPOINTS, HEAT INDICES OF 100 TO 110
DEGREES MAY STILL BE POSSIBLE. THEREFORE, EXPECT AT LEAST A
POTENTIAL FOR A HEAT ADVISORY TO BE ISSUED ACROSS PORTIONS OF THE
AREA ON SUNDAY AND MONDAY. ANY PRECIPITATION CHANCES ARE PRETTY MUCH
ZERO WITH SUBSIDENCE OVER THE FORECAST AREA.
LONG TERM
(TUESDAY THROUGH FRIDAY)
ISSUED AT 141 AM CDT SAT JUL 25 2026
THE REMAINDER OF NEXT WEEK WILL CONTINUE TO FEATURE VERY HOT
TEMPERATURES AND THE POTENTIAL FOR DAILY HEAT ADVISORIES. THE UPPER
RIDGE WILL CENTER MORE OVER NEW MEXICO, WHICH WILL BRING BACK NORTH
NORTHWESTERLY FLOW THROUGH THE WEEK. AFTERNOON CONVECTION ALONG THE
HIGHER TERRAIN IN COLORADO COULD BE DRIVEN SOUTHEAST BY ANY EMBEDDED
SHORTWAVES IN THE NORTHWEST FLOW ALOFT INTO NORTHERN OKLAHOMA DURING
THE LATE EVENING AND OVERNIGHT HOURS, BUT CURRENTLY THE CHANCES
REMAIN LOW. A WEAK COLD FRONT LATE IN THE WEEK MAY BRING SOME RELIEF
TO THE TRIPLE DIGIT HEAT BY NEXT WEEKEND.
