..SYNOPSIS/FORECAST...
SPLIT FLOW REGIME WILL CONTINUE ON SUNDAY WITH BUILDING HEIGHTS
ACROSS THE ERN HALF OF THE COUNTRY AND GRADUAL TROUGHINESS IN THE
WEST. THE PREDICTABILITY OF THE FLOW REGIME BEGINS TO DIMINISH BY
SUNDAY WITH PRIMARY UNCERTAINTY ON THE HANDLING OF THE UPR

APPEARS THAT THIS WAVE WILL INITIALLY DIG INTO NRN MEXICO LATE
SATURDAY...THEN EJECT NEWD TOWARD FAR W TX BY SUNDAY NIGHT AS
ANOTHER SPEED MAX APPROACHES SRN CA.
MODIFIED CP AIR MASS WILL CONTINUE TO FLOW NWD THROUGH THE PLAINS ON
SUNDAY AS PLUME OF STEEP LAPSE RATES STREAM NEWD FROM THE SRN
PLATEAU REGION. A BROAD REGION OF SCT SHOWERS WILL BE LIKELY WITHIN
THIS ZONE...BUT INCREASING CAP WILL PROHIBIT TSTM PROSPECTS SUNDAY
AFTN. MEANWHILE...AN INCREASING RISK FOR NOCTURNAL TSTMS WILL OCCUR
ALONG THE WRN EDGE OF THE MORE SUBSTANTIAL LOW-LEVEL MOISTURE AND
AHEAD OF THE EJECTING NRN MEXICO SYSTEM ACROSS WRN TX. ORGANIZED
SVR TSTMS ARE NOT LIKELY...HOWEVER...OWING TO ONLY MODEST
INSTABILITY/SHEAR EXPECTED.
