DISCUSSION
ISSUED AT 254 PM CDT MON SEP 7 2026
YET ANOTHER DAY CONTINUES WITH RIDGING AS THE PREDOMINANT WEATHER
INFLUENCE OVER THE FOUR STATE REGION. EACH DAY, CONVECTION
CONTINUES TO PERCOLATE ALONG THE PATCHES OF VORTICITY PROPAGATING
IN WESTWARD FLOW AROUND AND BETWEEN RIDGE AXES. TODAY'S PATCH
WILL RIDE ALONG THE EDGE OF A WEAK FRONTAL BOUNDARY WITH THE RIDGE
AXIS CENTERED ACROSS THE SOUTHERN GREAT PLAINS. THIS FRONTAL
BOUNDARY WILL LINGER ACROSS THE AREA INTO TUESDAY BEFORE DRIFTING
BACK NORTH AS A WARM FRONT BY THE MIDDLE OF THE WEEK, LEAVING A
DRIER DAY FOR WEDNESDAY BEFORE THE NEXT PATCH OF MOISTURE AND
VORTICITY LINES UP WITH AN APPROACHING FRONTAL BOUNDARY BY
THURSDAY. A GRADUAL COOLDOWN ENSUES AS A RESULT OF THIS ACTIVITY
(MID 90S), WHILE LONG-RANGE GUIDANCE SUGGESTS A PATTERN CHANGE BY
THE END OF THIS WEEK (TEMPERATURE MAXIMUMS LIKELY COOLER IN THE
LOW-TO-MID 90S) AS THE AFOREMENTIONED RIDGE FINALLY BREAKS DOWN,
BIFURCATED BY TROUGHING WITH AN ATTENDANT FRONTAL BOUNDARY THAT IS
EXPECTED TO ARRIVE LATER NEXT WEEKEND WITH MORE WIDESPREAD RAIN
CHANCES. RESULTING WPC QPF DAY 1-7 VALUES REFLECT AN OVERALL A
PRECIPITATION DISTRIBUTION THAT IS TRENDING WETTER IN
SOUTHEASTERLY ZONES WITH 0.01 TO 0.25 INCH RAINFALL TOTALS LIKELY
AREAWIDE AND 0.25-0.50 INCH TOTALS MORE LIKELY TO THE SOUTH WHERE
ANY ADDITIONAL CONVECTION CAN FORM. /16/
