DISCUSSION
(THIS EVENING THROUGH NEXT TUESDAY)
ISSUED AT 1206 PM CDT WED JUN 24 2026
RIDGING HAS STARTED TO SHIFT TO OUR WEST, WITH 500 MB HEIGHTS
FALLING ACROSS OUR REGION. WITH LOWER HEIGHTS, THE MID-LEVEL
SUBSIDENCE INVERSION WILL BE WEAKER, ALLOWING FOR A BRIEF WINDOW
OF TIME THIS AFTERNOON WHERE ISOLATED THUNDERSTORMS COULD OCCUR.
AFTER THIS RAIN CHANCES WILL BE NEAR ZERO FOR THE NEXT FIVE DAYS.
FOR THE REST OF THIS WEEK AND AS WE MOVE INTO THE WEEKEND, HIGH
PRESSURE WILL START TO ELONGATE AND MOVE EASTWARD. THIS PATTERN
WILL SUPPORT A DRY AND OVERALL QUIET STRETCH OF WEATHER, WITH POPS
STAYING AROUND 10%. WITH THIS RIDGING, SUBSIDENCE ALOFT WILL LEAD
TO MOSTLY CLEAR SKIES, AND TEMPERATURES WILL SLOWLY RISE THIS
WEEKEND AND THE START OF NEXT WEEK. HIGHS ALONG THE COAST WILL BE
IN THE LOW 90S WITH DEW POINTS IN THE MID 70S. FARTHER INLAND,
AFTERNOON HIGHS WILL BE IN THE MID TO UPPER 90S WITH A LOW CHANCE,
AROUND 15%, THAT WE COULD SEE TRIPLE DIGITS EARLY NEXT WEEK. HEAT
ADVISORIES WILL BE POSSIBLE EACH DAY NEXT WEEK, WITH HEAT INDEX
VALUES APPROACHING THE 108 THRESHOLD. WITH OR WITHOUT HEAT
ADVISORIES, EVERYONE SHOULD TAKE HEAT PRECAUTIONS BY STAYING
HYDRATED, TAKING BREAKS FROM THE HEAT, AND LIMITING ACTIVITIES
DURING THE HOTTEST PARTS OF THE DAY.
THROUGH THE FORECAST, THE RIDGE WILL SLOWLY SHIFT TO THE EAST, AND
BY THE MIDDLE OF NEXT WEEK, WE WILL BE ON THE EDGE OF THE RIDGE.
THIS WILL ALLOW FOR SHOWERS AND THUNDERSTORMS TO RETURN TO THE
FORECAST, WITH TYPICAL AFTERNOON SHOWERS AND THUNDERSTORMS.
