.DISCUSSION...
SHORT-WAVE AND ASSOCIATED CONVECTION CONTINUES ACROSS SOUTH CENTRAL
TEXAS. HAVE BOOSTED POPS AND QPF FOR TODAY AS SHORT-WAVE ONLY SLOWLY
PUSHES OFF TO THE EAST WHILE ENCOUNTERING MOIST AND UNSTABLE AIRMASS.
AFTER TODAY, MODELS SUGGEST THE SUBTROPICAL RIDGE WILL BUILD WEST
INTO SOUTHERN TEXAS AND NORTHEASTERN MEXICO FROM THE GULF OF MEXICO.
IN THE LONGER TERM, MODELS DISAGREE WITH MOST INDICATING A STRONGER
(ALBEIT SLIGHTLY WEAKER THAN SEASONABLE) RIDGE WHILE THE GFS HAS
AXIS FURTHER SOUTH AND EVEN WEAKER WITH A WESTERLY FLOW ACROSS THE
SOUTHER TIER OF STATES. FOR NOW WILL GO WITH SOMETHING IN BETWEEN
AND KEEP MAINLY SEABREEZE POPS AS A RESIDUAL SHEAR AXIS ENHANCES
CONVECTIVE DEVELOPMENT OVER SOUTHEASTERN CWA. DURING THE MIDDLE OF
THE WEEK, MODELS SUGGEST UPPER LOW OFF THE BAJA CALIFORNIA COAST
LIFTS OUT AND SENDS A SHORT-WAVE ACROSS THE SOUTHERN PLAINS. THIS
WILL MAKE FOR SOME POPS ACROSS MOST OF THE CWA AT MID WEEK. A
STRONGER SHORT-WAVE MOVING THROUGH THE PLAINS COULD BRING ANOTHER
FRONT INTO THE AREA OVER THE WEEKEND. TEMPERATURES WILL REMAIN BELOW
SEASONABLE AVERAGE TODAY DUE TO CLOUDS AND RAIN THEN WARM CLOSER TO
AVERAGE.
