...DISCUSSION...
A SPLIT FLOW UPPER AIR PATTERN WILL FEATURE A WEAKENING SHORTWAVE
TROUGH IN THE SUBTROPICAL BRANCH MOVING ACROSS THE CNTRL GULF COAST
STATES DURING THE DAY WHILE THE POLAR BRANCH DIGS SOUTHWARD OVER THE
WEST COAST AND EVOLVES INTO A VIGOROUS LOW/TROUGH OVER THE WESTERN
STATES BY SUNDAY NIGHT. ISOLATED SHOWERS/STORMS WILL PROBABLY BE
ONGOING SUNDAY MORNING OVER EAST TEXAS AND INTO ADJACENT PORTIONS OF
AR AND LA AS A COLD FRONT PUSHES SEWD ACROSS CNTRL TX AND THE
ARKLATEX REGION. ALTHOUGH LOW LEVEL MOISTURE WILL GRADUALLY
INCREASE THROUGH EARLY SUNDAY OVER THE TX UPPER COAST AND FEATURE
MID 60S DEWPOINTS...DESTABILIZATION WILL LIKELY REMAIN HINDERED BY
MODEST LAPSE RATES AND ONLY CONTRIBUTE TO WEAK BUOYANCY BEFORE THIS
ACTIVITY WEAKENS BY LATE IN THE DAY AS IT MOVES EASTWARD INTO LA.
THE PROGRESSIVE EASTWARD TRANSLATION OF THE CENTRAL GULF COAST
DISTURBANCE AND SUBDUED LOW LEVEL WIND PROFILE SUPPORTS A
CONTINUATION OF NO SEVERE PROBABILITIES ATTM.
