DISCUSSION
(THIS EVENING THROUGH NEXT WEDNESDAY)
ISSUED AT 1220 PM CDT THU APR 23 2026
THE SUBTROPICAL RIDGE STRETCHES FROM THE ATLANTIC INTO THE
NORTHERN GULF COAST WHILE LOW PRESSURE IS OVER THE CENTRAL PLAINS.
A HUMID ONSHORE FLOW REMAINS IN PLACE OVER THE LOCAL AREA BETWEEN
THESE FEATURES. ALOFT A SLIGHT WEAKNESS REMAINS.
DIURNAL HEATING HAS ALLOWED A SCATTERING OF SHOWERS AWAY FROM THE
COAST EARLY THIS AFTERNOON. THIS TREND WILL CONTINUE THROUGH
THE REMAINDER OF THE AFTERNOON WITH A DECREASE IN CONVECTION AS
SUNSET APPROACHES.
FRIDAY CONVECTION IS ANTICIPATED TO BLOSSOM OVER NORTH TEXAS WITH
DISTURBANCE. THE RESULTING QLCS WILL BE DRIVEN GENERALLY EAST WITH
A BIT OF A SOUTHERN DRIFT THROUGH THE EVENING. WHILE MOST
GUIDANCE KEEPS CONVECTION JUST NORTH OF OUR REGION, THERE IS A
SLIM CHANCE THAT THE SOUTHERN EDGE OF THE LINE DRIFTS IN, AND JUST
MAYBE TO THE I-10 CORRIDOR. WITH THE HIGH PWATS IN PLACE, STORMS
THAT DO DEVELOP MAY BE EFFICIENT RAINFALL PRODUCERS.
RIDGING BEGINS TO BUILD IN DURING THE WEEKEND REDUCING POPS,
HOWEVER ENOUGH DIURNAL HEATING IS EXPECTED TO ALLOW AT LEAST A
SLIGHT CHANCE OF CONVECTION EACH DAY NEXT WEEK. TEMPERATURES MAY
WARM INTO AN EARLY SUMMER PREVIEW EARLY NEXT WEEK WITH MID 80S TO
LOW 90S FORECAST MONDAY AND TUESDAY AFTERNOONS.
