DISCUSSION
ISSUED AT 237 PM CDT FRI SEP 4 2026
RIDGING CONTINUES TO BUILD AND SHIFT NORTHWESTWARD INTO THE
SOUTHERN GREAT PLAINS THE WEEKEND BEGINS. THIS RIDGE AXIS (AND
ITS EVOLUTION) MOSTLY TO OUR NORTH WILL SERVE AS THE PRIMARY
INFLUENCE ON WEATHER CONDITIONS THROUGH THE WEEKEND AND NEXT WEEK
INTO MID-SEPTEMBER. ZONAL FLOW UNDERNEATH THIS RIDGE WILL CONTINUE
TO STEER DISTURBANCES WESTWARD, AND COMBINED WITH LOWER
GEOPOTENTIAL HEIGHTS/WEAKER ATMOSPHERIC SUBSIDENCE, CONVECTIVE
ROUNDS WILL DEVELOP INHERITING THIS WESTWARD PROPAGATION. WITH DEW
POINTS REMAINING IN THE LOW 70S THROUGH THE WEEKEND, THE
POTENTIAL FOR HEAT HAZARD PRODUCT ISSUANCE ALSO REMAINS ELEVATED
(ESPECIALLY ALONG AND NORTH OF THE I-30 CORRIDOR INTO SOUTH
ARKANSAS. MEDIUM- RANGE GUIDANCE SUGGESTS A WINDOW OF SUNDAY
THROUGH TUESDAY FOR OUR GREATEST CHANCES (25 TO 50 PERCENT) OF
TEMPERATURES REACHING OR EXCEEDING 100 DEGREES, ESPECIALLY NORTH
OF THE I-20 CORRIDOR WHERE AIR REMAINS MORE SUBSIDENT. LONG-RANGE
GUIDANCE SUGGESTS MORE OF THE SAME AS SOMEWHAT WESTERLY ZONAL FLOW
ALOFT FUNNELS MORE PERTURBATIONS (INSTIGATING CONVECTION) IN OUR
DIRECTION. THAT SAID, THE CONVECTION THAT DOES DEVELOP WILL MOST
LIKELY BE IN THE FORM OF A DIURNAL PATTERN WITH THE BEST CHANCE OF
RAIN SOUTH OF THE I-20 CORRIDOR UNDER LESS INHIBITION FROM
RIDGING TO THE NORTH. RESULTING WPC QPF DAY 1-7 VALUES REFLECT
THAT DISTRIBUTION WITH 0.01 TO 0.25 INCH RAINFALL TOTALS LIKELY
NORTH OF I-20 AND 0.25-0.75 INCH TOTALS LIKELY TO THE SOUTH. /16/
