DISCUSSION...
LATEST ROUND OF STORMS ARE BEGINNING TO EXIT SOUTH CENTRAL
LOUISIANA AS TEMPERATURES AGAIN ARE HOLDING IN THE LOWER
70S THIS MORNING. IN THE DALLAS/FORT WORTH METROPLEX CURRENT
TEMPS ARE IN THE UPPER 50S WITH TEMPERATURES ACROSS THE
DAKOTAS IN THE 30S. WILL NOT SEE THOSE TEMPS UNTIL LATE NEXT
FALL.

FOR THIS MORNING HIGH PRESSURE IS CENTERED OFF THE CAROLINAS
WITH LOW PRESSURE MOVING UP TOWARDS THE GREAT LAKES AND A
TRAILING COLD FRONT EXTENDING DOWN INTO WEST TEXAS. SOUTH
WINDS REMAIN STRONG BUT WILL BACK OFF A BIT TODAY. TIDES
HAVE BEEN RUNNING A BIT ABOVE NORMAL ALONG THE COAST WITH
THE SOUTHERLY FETCH OVER THE LAST FEW DAYS. THIS WILL CHANGE
ON FRIDAY BEHIND THE COLD FRONT.

FOR TODAY LOOKING FOR THE UPPER LEVEL SYSTEM OVER THE
SOUTHERN ROCKIES CONT IT'S SLOW SWING DOWN AND INTO THE
FOUR CORNERS. THE COLD FRONT MOVING THROUGH CENTRAL TEXAS
WILL CONTINUE THAT SLOW MARCH TOWARDS THE GULF TODAY. THE
COMBINATION OF THE APPROACHING FRONT... INTRUSION OF GULF
MOISTURE AND THE UPPER LEVEL LOW WILL BRING MORE SHOWERS
AND THUNDERSTORMS AGAIN TO THE NORTHWEST GULF REGION. AS
TEMPS REMAIN AROUND 70 NOT LOOKING A LARGE JUMP BUT TEMPS
WILL MANAGE TO TOP OUT IN THE UPPER 70S TO NEAR 80. THE
CHANCE FOR RAINS WILL CONTINUE INTO FRIDAY AND TAPER OFF
BEHIND THE FRONT. THIS NEXT FRONT CONTINUES TO SLOW WITH
EACH MODEL RUN AND THE LATEST MODEL RUN IS NO DIFFERENT.
THE LATEST RUNS ARE SUGGESTING TOWARDS MIDNIGHT FOR BPT
AND AROUND MIDNIGHT FOR LCH AND DRG THE EARLY MORNING FOR
LFT.

RAINS TO CONTINUE INTO FRIDAY BEHIND THE FRONT BUT WILL BE
DRAWING TO A CLOSE. THE GRADIENT IS EXPECTED TO TIGHTEN
OVER THE COASTAL WATERS LATE FRIDAY INTO SATURDAY AND ANOTHER
SMALL CRAFT ADVISORY MAYBE NEEDED AT THAT TIME. OTHERWISE
LOOKING AT COOL MORNINGS OVER THE WEEKEND WITH TEMPS WARMING
BACK TOWARDS THE 70S FOR DAYTIME HIGHS.
