SHORT TERM (TODAY THROUGH FRIDAY)...
MID TO UPPER LEVEL RIDGE HAS PUSHED UP INTO TEXAS AS A TROUGH
MOVED TO THE MISSISSIPPI VALLEY. AT THE SURFACE...HIGH PRESSURE IS
CENTERED OVER THE GULF OF MEXICO. VAD WIND PROFILES FROM AREA
RADARS SHOW SOUTHERLY FLOW IN THE BOUNDARY LAYER UP TO ABOUT 7KFT.
THIS WILL LEAD TO STRATOCU DECK FORMING THIS MORNING OVER THE
EASTERN HALF OF THE CWA. UPPER RIDGE WILL MEAN CLEARING DURING THE
AFTERNOON AND A WARM DAY. HIGH TEMPS WILL BE A FEW DEGREES ABOVE
NORMAL. LITTLE CHANGE IN THE PATTERN OVER THE NEXT DAY OR SO WILL
MEAN A REPEAT FOR TONIGHT AND FRIDAY.

LONG TERM (FRIDAY NIGHT THROUGH WEDNESDAY)...
MODELS ARE TRENDING TOWARD A STRONGER UPPER RIDGE IN THE LONGER
TERM. THIS WILL LOWER CHANCES FOR ANY PRECIP THROUGH THE WEEKEND.
NOW IT LOOKS LIKE ANY CHANCE FOR RAIN WILL NOT COME UNTIL MONDAY

EASTERN COUNTIES. HAVE INCLUDED SLIGHT CHANCE POPS MONDAY AND
TUESDAY AFTERNOONS. TEMPERATURES WILL CONTINUE ABOVE NORMAL...BUT
WILL STAY FAIRLY STEADY THROUGH THE PERIOD. HAVE INCREASED THEM A
