WILL STRUGGLE TO ADVANCE INLAND AS A PROPENSITY FOR OFFSHORE FLOW IS
EXPECTED THROUGH THE PERIOD. LATE THIS WEEKEND SELY LOW LEVEL
TRAJECTORIES MAY ALLOW MOISTURE/WEAK INSTABILITY TO RETURN TO
PORTIONS OF TX. AT THAT TIME DEEP CONVECTION MAY ULTIMATELY EVOLVE
ACROSS THE SRN PLAINS IF SHORT-WAVE DEPICTED BY MODELS MATERIALIZES.
