Area forecast discussion, May 2, 9:45 AM CDT, 1 hour 47 minutes before

DEEP SOUTH TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
945 AM CDT TUE MAY 2 2000

OUTFLOW BOUNDARY JUST TO OUR NORTH WILL BE MOVING SOUTH DURING THE
LATE MORNING AND AFTERNOON.  THIS WILL LIKELY BE A TRIGGER FOR
ADDITIONAL THUNDERSTORM ACTIVITY.  WILL GO ALONG WITH CURRENT ZONES
WITH MENTION OF SVR TSMS AS PER SPC DAY 1 DISCUSSION.  OUR VWP
CONTINUES TO SHOW 35-45 KTS OF WIND IN THE LOWEST 10KFT.  THE
MORNING SOUNDING SHOWS GOOD INSTABILITY WHILE THE LATEST MODEL RUNS
SHOW ANOTHER S/W TROF ROTATING AROUND THE SOUTHERN BASE OF MAIN
TROF.  S/W IS CURRENTLY OVER THE BIG BEND AREA BUT VORTICITY
ADVECTION SHOULD BE AFFECTING THE AREA BY AFTERNOON.  THIS ALONG
WITH THE INTERACTION OF THE BOUNDARY SHOULD MAKE FOR AN INTERESTING
AFTERNOON AND EVENING.  THE THING THAT COULD HAPPEN WOULD BE THE
BOUNDARY OUTRUNS THE APPROACHING VORTICITY AND WE SOCKED IN WITH
CLOUDS AND COOLER STABLE AIR.  THAT WOULD KNOCK DOWN OUR POP CHANCES
CONSIDERABLY.

IT DOES LOOK LIKE THE MAIN TROF AXIS WILL BE THROUGH THE AREA BY WED
MORNING SO TOMORROW SHOULD BE MUCH IMPROVED.

WILL BE ISSUING A HWO SHORTLY.
