.DISCUSSION...
WX MAP SHOWS SFC HIGH RETREATING NE OF THE REGION...ALLOWING FOR A
RETURN FLOW ACROSS THE NW GULF INTO SE TX. TEMPS AGAIN IN THE 60S
THIS MORNING WILL LIKELY BE THE LAST WE WILL SEE FOR A LITTLE
WHILE.

ALOFT...UPPER LOW OFF THE SE LA/MS COAST WILL LIFT NE TODAY...WITH
ANOTHER SHARP SHORTWAVE TROF EXPECTED TO CUT OFF OVER THE ARKLATEX
SUN. THIS UPPER LOW WILL BASICALLY PARK OVER SE TX/LA THRU THE
END OF NEXT WEEK. THIS WILL GRADUALLY LEAD TO INCREASING POPS
ACROSS THE REGION STARTING MON WITH A SLIGHT CHANCE...WITH BETTER
CHANCES BEGINNING TUE-FRI. TEMPS EXPECTED TO RETURN TO LATE SUMMER
VALUES...MID 70S FOR LOWS...AND LOWER/MID 90S FOR HIGHS.

ERIKA...WHICH IS A PRETTY SHEARED AND SLOPPY SYSTEM THIS MORNING...NOT
EXPECTED TO AFFECT THE REGION. FORECAST TRACK...IF IT
SURVIVES...PLACES IT OVER CUBA THE NEXT COUPLE OF DAYS...AND THE
EASTERN GULF BY MON-TUE...MAINLY AFFECTING FL WITH LOTS OF RAIN.
THE UPPER LOW/TROF MENTIONED ABOVE WILL KEEP IT EAST OF THE
REGION...AND LIKELY VERY SHEARED FOR THE REMAINDER OF THE PERIOD.
NOW MOISTURE FROM ITS REMNANTS MAY BE ENTRAINED WITHIN THE UPPER
LOW OVER OUR REGION BY THU-FRI...KEEPING SLIGHTLY HIGHER POPS INTO
NEXT WEEKEND.
