SHORT TERM
(THROUGH SUNDAY)
ISSUED AT 1130 PM CDT SAT JUL 25 2026
00Z SOUNDINGS AND 24 HR DEWPOINT CHANGE PLOTS SHOW THE WESTWARD
EXPANDING DRIER AIR ALONG WITH THE INCREASINGLY WARM THERMAL
PROFILES. THE RESULT WILL BE HOTTER TEMPERATURES AND SOMEWHAT
LOWER AFTERNOON DEWPOINTS WHICH YIELD SIMILAR AFTERNOON HEAT INDEX
VALUES TO THOSE OBSERVED ON SATURDAY. AS SUCH THE HEAT HEADLINES
HAVE BEEN ADJUSTED TO FOLLOW A SIMILAR FOOTPRINT.
LONG TERM
(MONDAY THROUGH SATURDAY)
ISSUED AT 1130 PM CDT SAT JUL 25 2026
MONDAY AND TUESDAY ARE LIKELY TO SEE CONTINUED DANGEROUS HEAT
LEVELS. THE WEAK MID WEEK FRONTAL BOUNDARY CONTINUES TO BE SHOWN
IN GUIDANCE WITH VARYING DEGREES OF INFLUENCE BOTH IN COOLER
TEMPERATURES AND ASSOCIATED PRECIP CHANCES. A GRADUAL WESTWARD
SHIFT OF THE UPPER HIGH FROM MID TO LATE WEEK SEEMS MORE LIKELY
AND THIS WOULD ALSO KEEP TEMPS A FEW DEGREES COOLER. WHILE
FORECAST DETAILS CONTAIN UNCERTAINTY, THE OVER ARCHING THEME OF
HOT WEATHER THROUGH MUCH OF THE UPCOMING WEEK REMAINS IN PLACE.
