COASTAL BEND FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
230 PM CST THU MAR 9 2000

PARTLY CLOUDY...WARM...AND HUMID CONDITIONS ACROSS THE REGION THIS
AFTERNOON. TEMPS HAVE EXCEEDED PREVIOUS FORECAST...AND REQUIRED AN
UPDATE EARLIER THIS AFTERNOON.

UPPER LOW AND TROF DEEPEN AND DIGS SOUTH ACROSS N TX AND OK OVER THE
NEXT 48 HOURS. A COLD FRONT WILL PUSH THROUGH THE AREA FRIDAY
NIGHT/SATURDAY MORNING...WITH DECENT VERTICAL LIFT AHEAD OF THE
BOUNDARY. AS HAS BEEN THE CASE THIS YEAR...THIS FRONT WILL HAVE THE
BEST DYNAMICS TOO FAR NORTH TO EXPECT WIDESPREAD RAINFALL.
ADDITIONALLY...THE SOUTHERN CWA WILL FALL INTO THE DREADED SOUTHWEST
FLOW IN THE MID LEVELS PRIOR TO FROPA...WHICH WILL EFFECTIVELY CHOKE
OFF CONVECTION FOR THOSE SECTIONS. THE BEST CHANCES FOR ANY ACTIVITY
WILL BE CONFINED TO THE NORTHEASTERN CWA...THEREFORE WILL SHADE
POPS HIGHER IN THOSE AREAS.

TEMPERATURES FOR FRI ARE INFLUENCED BY THE WARM HIGHS TODAY. MESO
ETA HAD A GOOD HANDLE ON THE TEMPS TODAY...AND WILL USE ITS GUIDANCE
TO SHADE TEMPS WARMER.

AFTER FROPA...STRONG NORTH WINDS WILL ADVECT DRY AIR INTO THE AREA.
WITH THE PROGRESSIVE NATURE OF THE UPPER LOW...EXPECT TO SEE
CLEARING QUICKLY ON SATURDAY...AND COOLER TEMPERATURES. WE MAY EVEN
SEE SLIGHTLY COOLER THAN NORMAL TEMPERATURES OVER THE WEEKEND!

MARINE...NO FLAGS. SCA EXPECTED FOLLOWING FROPA FRIDAY NIGHT AND
SATURDAY.
