DISCUSSION
ISSUED AT 159 AM CDT THU SEP 3 2026
UPPER-LEVEL RIDGING WILL CONTINUE TO DOMINATE THE REGIONAL
WEATHER, THOUGH WILL SHIFT FROM THE MID-SOUTH TO HIGH PLAINS AND
THEN BACK AGAIN OVER THE NEXT SEVERAL DAYS. HEAT WILL BE A FACTOR
IN THE WEATHER AS THIS RIDGE REMAINS STOUT. CLOSER TO THE GULF
COAST, HOWEVER, WE WILL SEE INCREASING RAIN CHANCES ASSOCIATED
WITH AN EASTERLY WAVE BRING A SURGE OF DEEPER MOISTURE AND ERODING
THE EDGE OF THE RIDGE. RAIN CHANCES MAY NUDGE BACK TO THE SOUTH
WHEN THE RIDGE CENTERS OVER THE HIGH PLAINS OVER THE WEEKEND, BUT
MOST DAYS EVEN A STRAY SHOWER OR STORM COULD OCCUR IN NORTHERN
PARTS OF OUR CWA. LOCALLY HEAVY RAINFALL WITH DEEP TROPICAL
MOISTURE IN PLACE WILL BE A POSSIBLE CONCERN. AND WHEREVER RAIN
DELAYS UNTIL AFTERNOON HOURS, HEAT INDEX VALUES WILL STILL
APPROACH THE 105+ RANGE EACH DAY. EXPECT ADDITIONAL HEAT ADVISORY
HEADLINES FOR AT LEAST PARTS OF THE AREA INTO NEXT WEEK. /NF/
