AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
345 AM CDT THU MAY 1 2008

.DISCUSSION...THE MAIN FEATURE THAT WILL BE CONTROLLING THE WX OVER
DEEP SOUTH TX OVER THE NEXT SEVERAL DAYS WILL BE A MAJOR 500 MB LOW
AND ASSOCIATED SURFACE LOW SPINNING OVER THE NORTHWESTERN U.S. THIS
FEATURE WILL PUSH EAST TOWARDS THE GREAT LAKES THIS WEEKEND. THIS
WILL PULL A COLD FRONT SOUTH TO NEAR THE BRO CWA LATE SAT AND SUN.
THE GFS AND THE ECMWF ARE MAINTAINING GOOD CONSISTENCY IN SHOWING
ONLY A WEAK FROPA AT BEST THROUGH THE BRO CWA WITH THE POTENTIAL
EXISTING THAT THE FRONT WILL STALL NEAR OR NORTH OF THE BRO AREA.
MOISTURE LEVELS REMAIN LIMITED IN THE SHORT TERM THROUGH SAT AND
WILL NOT MENTION ANY SIGNIFICANT POPS. STEADY WAA WILL PERSIST AHEAD
OF THIS NEXT SYSTEM RAISING UP TEMPS. THE CURRENT MAV AND MET TEMP
GUIDANCE ARE IN GENERAL AGREEMENT FOR HIGHS WITH THE MAV HAVING A
WARM BIAS VERSUS THE NAM FOR LOWS. WITH CURRENT DEWPOINTS AROUND THE
LOWER RGV RANGING IN THE UPPER 60S TO NEAR 70 DEGREES WILL LEAN
TOWARDS THE WARMER MAV NUMBERS FOR MINS OVER THE NEXT COUPLE OF
NIGHTS. AFTER THE FIRST 500 MB FEATURE EXITS TO THE NORTHEAST...
ANOTHER STRONG TROUGH/CLOSED LOW WILL DIG ACROSS THE SOUTHWESTERN
U.S. IN THE 3 TO 7 DAY RANGE WHICH WILL ADVECT SOME BETTER MOISTURE
VALUES OVER THE REGION FROM LATE SAT THROUGH MON.  THE DEEPER
MOISTURE VALUES WILL THEN SHIFT FURTHER NORTH OF THE BRO REGION
LATER NEXT WEEK AS THE 500 MB TROUGH MOVES OVER CENTRAL AND NORTHERN
TX NEXT WED.  RUN TO RUN CONSISTENCY OF THE GFS MEX GUIDANCE IS
PRETTY GOOD AND WILL MAINTAIN SOME SLGT CHC POPS IN PLACE FOR SUN
AND MON DUE TO THE BETTER MOISTURE ADVECTION. MODEL TO MODEL
CONSISTENCY BETWEEN THE GFS AND THE ECMWF HAS IMPROVED SINCE
YESTERDAY THROUGH TUES NIGHT WITH BOTH MODELS THEN DIVERGING ON AND
AFTER WED. DUE TO THE PRETTY GOOD AGREEMENT OVER THE LAST SEVERAL
RUNS OF THE MEX MOS...WILL STICK FAIRLY CLOSE TO THESE OVERALL
TRENDS THROUGH DAY 7 FOR POPS AND TEMPS.
