DISCUSSION
ISSUED AT 104 PM CDT TUE JUL 28 2026
OUR STUBBORN HIGH PRESSURE OVER THE DESERT SOUTHWEST AND ASSOCIATED
AREA OF RIDGING WILL KEEP THE ARKLATEX MOSTLY DRY AND VERY HOT FOR
AT LEAST ANOTHER DAY, THUS HAVE EXTENDED OUR HEAT ADVISORY ANOTHER
24 HOURS, NOW IN EFFECT THROUGH 8 PM WEDNESDAY EVENING.
THE EASTERN EXTENT OF THE RIDGING WILL KEEP THE FOUR STATE REGION
FIRMLY IN ITS GRIP OVERNIGHT, KEEPING QUIET AND MUGGY CONDITIONS IN
PLAY WHILE LOWS DROP INTO THE MIDDLE TO UPPER 70S AREAWIDE. TOMORROW
WILL SEE MUCH OF THE SAME FOR THE MAJORITY OF THE REGION AS HIGHS
QUICKLY CLIMB BACK INTO THE UPPER 90S TO LOWER 100S WHILE DEW POINTS
REMAIN MUGGY ENOUGH TO PUSH HEAT INDICES BACK ABOVE 105 THROUGH THE
AFTERNOON. CONTINUE TO PRACTICE HEAT SAFETY TECHNIQUES, LIMITING
OUTDOOR EXPOSURE AND EXERTION, WEARING LIGHT-COLORED, LOOSE-FITTING
CLOTHING, AND KEEPING HYDRATED.
OUR NORTHEASTERN ZONES MAY BEGIN TO BE AFFECTED BY THE UPCOMING
PATTERN SHIFT AS SOON AS TOMORROW AFTERNOON, HOWEVER. THE HIGH
PRESSURE WILL START TO RETROGRADE WESTWARD OVER THE FOUR CORNERS
REGION, OPENING THE DOOR FOR TROUGHING TO SLIDE A WEAK BOUNDARY DOWN
THE MISSISSIPPI VALLEY, KICKING UP SHOWERS AND STORMS ACROSS
ARKANSAS. IF THE RIDGING RELENTS ADEQUATELY IN TIME, SOME OF THESE
SHOWERS MAY MANAGE TO PUSH INTO OUR SOUTHWEST ARKANSAS ZONES DURING
THE AFTERNOON HOURS TOMORROW, PROVIDING SOME RELIEF FROM THE HEAT.
THE PATTERN SHIFT WHICH BEGINS TOMORROW WILL ATTEMPT TO CONTINUE
THROUGH THE END OF THE WEEK AND INTO THE WEEKEND, OPENING THE DOOR
FOR INCREASING CHANCES OF STORMS ACROSS OUR EASTERN ZONES THURSDAY,
RECEDING SOMEWHAT FRIDAY AND RETURNING INTO THE WEEKEND AS A
SHORTWAVE SWINGS A FRONTAL BOUNDARY SOUTH. COVERAGE OF IMPACTS LOOKS
LIMITED AT BEST, BASED ON THE LATEST MODEL RUNS. THUS OUR
NORTHEASTERN ZONES MAY ENJOY SOME RELIEF FROM THE HEAT BUT AREAS
SOUTH AND WEST WILL STILL LIKELY SEE HEAT INDICES ABOVE 100 THROUGH
SATURDAY BEFORE TEMPERATURES FINALLY DROP OUT OF THE UPPER 90S
SUNDAY, WARMING AGAIN GOING INTO EARLY NEXT WEEK. SCATTERED CHANCES
OF AFTERNOON THUNDERSTORMS WILL PERSIST THROUGH THE END OF THIS
EXTENDED FORECAST PERIOD.
