.DISCUSSION...
UPDATED ZONE FORECASTS DUE TO ISSUANCE OF SEVERE THUNDERSTORM WATCH
NUMBER 578.

&&

.PREVIOUS DISCUSSION...
WATCHING AN MCS BARREL ACROSS N TX...WEAKENING AT THIS TIME.
HOWEVER...AS THE REMNANT VORT MAX SLIDES SE ACROSS E TX...EXPECT
SHRA/TSRA TO DEVELOP ACROSS INLAND SE TX BY LATE MORNING...AND THE
REMAINDER OF SE TX...S LA BY THE AFTERNOON. BELIEVE THE BULK OF THIS
SYSTEM WILL MISS C LA REGION...BUT LEFT 30% AND WARMER TEMPS THERE.
MOST OF THE ACTIVITY SHOULD DIE OFF BY 9 PM TONIGHT.

FOR SUN...EXPECT THE MID/UPPER LEVEL TROF OVER OUR AREA TO SLOWLY
START FILLING AS MID/UPPER HIGHS FROM BOTH THE EAST AND WEST START
INTENSIFYING. THIS WILL LEAVE WEAKER WINDS ALOFT...AND REDUCED
CHANCES FOR SHRA/TSRA. LEFT 30% I-10 SOUTH MAINLY FOR SEA-BREEZE
ACTIVITY...AS WE WILL HAVE A SOUTHERLY FLOW IN THE LOWER LEVELS. ONLY
WENT WITH 20% AND MUCH WARMER I-10 NORTH. FOR MON...JUST WENT WITH
20% AREAWIDE...AS WE WILL BE FIRMLY UNDER THE INFLUENCE OF HIGH
PRESSURE A THE SURFACE AND ALOFT.

TUE THE FORECAST GETS INTERESTING...AS IT INVOLVES THE TROPICAL WAVE
THATS ACROSS THE NW CARIBBEAN THIS MORNING. THE NAM IS INSISTENT ON
CLOSING OFF THE WAVE...BRINGING IT ACROSS THE YUCATAN...AND NW ACROSS
THE CENTRAL GULF...AN JUST SOUTH OF THE LA COAST BY TUE. THE GFS...
HOWEVER...LEAVES IT AS AN OPEN WAVE...AND A BIT FASTER...BRINGING
COPIOUS AMOUNTS OF TROPICAL MOISTURE TO THE ENTIRE AREA FOR TUE AND
WED. NCEP WENT WITH THIS SOLUTION SOMEWHAT.  I DID LEAVE HIGHER POPS
IN LFT REGION THAN LCH...AEX...AND BPT...MAINLY FOR SPEED PURPOSES.
HOWEVER...ANYTHING GOES THIS TIME OF YEAR...SO STAY TUNED. FOR THE
REST OF THE EXTENDED...WENT WITH CLIMO POPS. ALSO WENT WITH SLIGHTLY
WARMER TEMPS AT NIGHT...DUE TO THE WATER TEMPS BEING IN THE UPPER 80S
ACROSS OUR COASTAL WATERS...AND DURING THE DAY DUE TO THE EXTREMELY
DRY GROUND.
