KEY MESSAGES
ISSUED AT 1221 PM CDT SAT JUL 25 2026
- HAZARDOUS HEAT RETURNS THROUGH THE WORK WEEK WITH ELEVATED
POTENTIALS OF TEMPERATURE MAXIMUMS IN THE LOWER 100S.
- THE NEXT CHANCE FOR RAIN WON'T BE UNTIL AT LEAST MID-WEEK, ONCE
NORTHWEST FLOW RETURNS TO THE ARK-LA-TX.
DISCUSSION
ISSUED AT 1221 PM CDT SAT JUL 25 2026
THE RIDGE OVER THE SOUTHWEST CONUS CONTINUES TO KEEP THE ARK-LA-TX
DRY APART FROM THE FEW SHOWERS SEEN THIS MORNING. THE RIDGE
WORKING WITH CONTINUED SOUTHERLY FLOW AT THE SURFACE WILL KEEP
HEAT AS THE PRIMARY HAZARD FOR MUCH OF THE FORECAST PERIOD
BEGINNING TOMORROW. A HEAT ADVISORY HAS BEEN ISSUED AREAWIDE FOR
SUNDAY AND WILL BE RE-EVALUATED FOR EXTENSION IN FUTURE FORECAST
PACKAGES, BUT VERY LITTLE IS EXPECTED TO CHANGE THROUGH THE SHORT-
TERM. IF THERE ARE ANY OUTDOOR PLANS FOR THIS WEEK, MAKE SURE TO
TAKE PRECAUTIONS AND FREQUENT BREAKS FROM THE HEAT TO PREVENT
HEAT-RELATED ILLNESS. ALSO BE SURE TO CHECK ON NEIGHBORS AND
LOVED ONES. CHILDREN, THE ELDERLY, AND PEOPLE WITH CHRONIC HEALTH
CONDITIONS ARE MORE SUSCEPTIBLE TO HEAT-RELATED ILLNESS AND
COMPLICATIONS.
LONG-RANGE MODELS HAVE THE WAVELENGTH OF THE RIDGE OUT WEST
DECREASING BY MID-WEEK. THIS WOULD BRING NORTHWEST FLOW BACK TO THE
REGION AND OPEN THE DOOR FOR RAIN SHOULD ANY DISTURBANCES IN THAT
FLOW OCCUR. ANY RAIN AND INCREASED CLOUD COVER COULD OFFER A
BRIEF REPRIEVE FROM THE HEAT. THE HEAVY RAINFALL IN RECENT MONTHS
HAS WORKED TO LESSON DROUGHT CONDITIONS BUT THEY WILL LIKELY BEGIN
TO WORSEN AGAIN WITH PROLONGED HEAT AND MINIMAL RAIN.
