KEY MESSAGES
ISSUED AT 611 AM CDT FRI JUN 26 2026
- HEAT & HUMIDITY: A SIGNIFICANT WARMING TREND BEGINS LATE THIS
WEEK. HEAT INDICES ARE EXPECTED TO APPROACH OR EXCEED 100
DEGREES DAILY FROM FRIDAY THROUGH THE MIDDLE OF NEXT WEEK. THIS
WILL POSE A MODERATE TO MAJOR HEAT RISK OVER THE MAJORITY OF THE
REGION.
DISCUSSION
(TODAY THROUGH THURSDAY)
ISSUED AT 1205 AM CDT FRI JUN 26 2026
THROUGH THE SHORT TERM, LOW CHANCES FOR CONVECTION WILL BE
PRESENT DUE TO A DETERIORATING SURFACE BOUNDARY MEANDERING ACROSS
PORTIONS OF ALABAMA. THIS BOUNDARY WILL INTERACT AND ENHANCE
CONDITIONS WITH AN UPPER SHORTWAVE MOVING THROUGH THE BASE OF AN
EASTERN CONUS TROUGH. AFTER FRIDAY, THE UPPER TROUGH WILL PUSH
EASTWARD. AT THE SAME TIME OVER THIS WEEKEND, A LARGE UPPER RIDGE
WILL DEVELOP ACROSS THE MIDSECTION OF THE US INCLUDING TEXAS, THE
PLAINS, MISSISSIPPI VALLEY, AND INTO THE DEEP SOUTH. IN THE LOWER
LEVELS, THE DETERIORATING SURFACE BOUNDARY WILL DISSIPATE. ANY
FRONTS ARE EXPECTED TO REMAIN WELL TO THE NORTH OF THE DEEP
SOUTH, AND SURFACE RIDGING IS EXPECTED TO DEVELOP ACROSS MUCH OF
EASTERN CONUS THROUGH THE EXTENDED. IT IS IMPORTANT TO NOTE THAT
AN UPPER RIDGE DOES NOT ALWAYS MEAN ZERO RAIN CHANCES. THAT
DEPENDS ON THE STRENGTH OF THE RIDGE. IN THIS CASE, SOME WEAK
DISTURBANCES WILL BE POSSIBLE AROUND THE RIDGE. WITH HOT
AFTERNOON SUMMER TEMPERATURES, RAIN CHANCES WILL BE ISOLATED AND
DIURNALLY INDUCED, BUT NOT NECESSARILY ZERO. TEMPERATURES WILL
CREEP UPWARD AS WE HEAD TOWARD THE END OF JUNE INTO EARLY JULY
WITH OVERALL HEAT STRESS BECOMING A CONCERN AS WE HEAD INTO THIS
WEEKEND AND INTO THE MIDDLE OF NEXT WEEK. CURRENT TRENDS ARE
LEANING TO A HEAT ADVISORY BECOMING NECESSARY BY MONDAY OF NEXT
WEEK.
