DISCUSSION...
SHORTWAVE THAT HELPED PRODUCE SCT AREAS OF -RA OVER NORTH TX LAST
NIGHT HAS MOVED OUT OF SE TX THIS MORNING. OTHERWISE NOT A LOT OF
ISSUES WITH THE FCST THE NEXT FEW DAYS AS THE UPPER RIDGE REMAINS
TRAPPED BETWEEN THE TWO ROBUST LOWS ANCHORED ON BOTH U.S. COASTS.
WEAKER CAA TODAY BUT THE COOL/DRY AIRMASS ALREADY IN PLACE ACROSS
THE STATE WILL KEEP THINGS QUIET HERE.

CHANGES WITH THE UPPER PATTERN STILL PROGGED BY THIS WEEKEND...AS
THE SYSTEM OUT EAST FINALLY MOVES OFF THE COAST. THE INCREASINGLY
SW FLOW ALOFT WILL BE COINCIDING WITH THE RETURN OF ONSHORE WINDS
(AND LOW-LEVEL MOISTURE) LATE FRI INTO SUN AS THE SYSTEM OUT WEST
BEGINS TO MOVE INTO THE SRN PLAINS. RAIN CHANCES ARE NOT EXPECTED
TO RETURN TO THE CWA UNTIL LATE SUN/MON (THEN PERSISTING INTO THE
EARLY PART OF THE WEEK) AS EMBEDDED DISTURBANCES BEGIN TO MOVE A-
CROSS THE REGION. TIMING OF THESE DISTURBANCES WILL LIKELY BE THE
MAIN ISSUE IN THE EXTENDED FCST. 41

MARINE...
LIGHT OFFSHORE WINDS WILL CONTINUE WITH A WEAK COLD FRONT OVER
OKLAHOMA TO MOVE INTO THE COASTAL WATERS THURSDAY MORNING LEADING TO
A BRIEF INCREASE IN OFFSHORE WINDS.  HIGH PRESSURE SETTLES IN TO THE
AREA AND THEN SHIFTS EASTWARD TURNING WINDS AROUND TO THE EAST
