AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
242 AM CDT MON SEP 18 2006

.DISCUSSION...INTERESTING EVENING AS MCS AND ASSOCIATED LINE OF
STORMS IS PASSING ACROSS THE CWA. THE NORTHWESTERN PORTIONS OF THE
CWA HAD THE HEAVIEST RAIN WITH RADAR ESTIMATES BETWEEN 3 AND 6
INCHES IN ZAPATA AND JIM HOGG COUNTIES. LINE OF STORMS WILL BE
PASSING THROUGH KENEDY...HIDALGO...WILLACY AND CAMERON BETWEEN 2
AND 5 AM. THE MCS STARTED OFF SLOW BUT IS NOW PICKING UP SPEED AS
IT HEADS NORTHEAST...SOME BACK BUILDING IS OCCURRING THUS THE
MENTION OF TSTMS MOVING THROUGH THE SOUTHERN PORTIONS OF THE CWA.

THE COLD FRONT HAS MADE SOME SOUTHWARD PROGRESS OVERNIGHT THANKS
TO SOME EARLIER MINOR PRESSURE RISES BEHIND THE FRONT AND THE
CONVECTION AHEAD OF THE FRONT. HOWEVER...THE PRESSURE RISES ARE
EXPECTED TO DIMINISH TEMPORARILY WHICH SHOULD HELP SLOW DOWN THE
FRONTS PROGRESS THIS MORNING. MAJORITY OF CURRENT THUNDERSTORMS COULD
BE OUT OF THE PICTURE AROUND OR SHORTLY AFTER SUNRISE...BUT WITH
THE FRONT LINGERING TO OUR NORTH MOISTURE WILL CONTINUE TO POOL TO
THE SOUTH. THUS...THUNDERSTORMS ARE EXPECTED TO RE-FIRE LATER
TODAY AND EARLY THIS EVENING WITH BEST CHANCES ACROSS THE EASTERN
HALF OF THE CWA. HEAVY RAIN WILL BE MENTIONED BUT A FLASH FLOOD
WATCH IS NOT ANTICIPATED AS STORMS SHOULD MOVE AT A DECENT PACE
ALSO AREAL COVERAGE OF THE STRONGEST TSTMS SHOULD NOT BE THAT
EXTENSIVE.

HAVE RESORTED TOWARDS THE NAM MODEL FOR THE FIRST HALF OF THE
FORECAST THEN LEANING TOWARDS A MIX OF GFS/ECMWF FOR THE LATTER
HALF. BIG DIFFERENCES EXIST BETWEEN THE NAM AND GFS WITH THE
FRONTS TIMING AND CLEARING OF MOISTURE BEHIND THE FRONT. THE NAMS
TIMING OF THE FRONTAL PASSAGE REMAINS CONSISTENT WITH A PREFRONTAL
TROUGH PASSING TONIGHT AND THE MAIN FRONT TUESDAY MORNING WITH
VERY DRY AIR TO FILTER THROUGH THE VALLEY THROUGH WEDNESDAY AS
HIGH PRESSURE ALOFT AND AT THE SURFACE BUILDS INTO THE REGION. THE
GFS MEAN WHILE HAS SPED UP THE FRONT TREMENDOUSLY OVER THE LAST
SEVERAL RUNS AND PUSHES IT THROUGH TONIGHT BUT KEEPS RAIN CHANCES
AND MOISTURE LEVELS VERY HIGH. A CLOSER LOOK INDICATES THAT SOME
CONVECTIVE FEEDBACK CORRUPTS THE GFS WHICH RESULTS IN POPS STAYING
OVER THE RIO GRANDE VALLEY THROUGH THURSDAY MORNING. OUR FORECAST
SHOWS RAIN TAPERING OFF THROUGH TUESDAY WITH DRY CONDITIONS TO
PREVAIL THROUGH FRIDAY. AS FOR TEMPERATURES TEMPERATURES WILL
TREND TOWARDS NORMAL THROUGH WEDNESDAY

FINALLY...NEXT UPSTREAM UPPER TROUGH AND FRONT TO AFFECT THE
VALLEY NEXT WEEK. MOISTURE AND TEMPERATURES INCREASE THURSDAY
THROUGH FRIDAY WITH RAIN CHANCES REENTERING THE FORECAST FRIDAY
NIGHT AND OVER THE WEEKEND WITH EXACT TIMING UNSURE THIS FAR OUT.
MORE ON THIS AS SYSTEM TAKES SHAPE.

PASS THROUGH THE ADJACENT COASTAL WATERS OF DEEP SOUTH TEXAS
TONIGHT AND TUESDAY MORNING. MODERATE WINDS AND SEAS WITH
SCATTERED SHOWERS AND THUNDERSTORMS CAN BE EXPECTED IN ADVANCE AS
WELL AS ACCOMPANY THE PASSAGE OF THE FRONT TODAY THROUGH TONIGHT.
