   ...SYNOPSIS...
   
   THE PRIMARY FEATURE OF INTEREST THIS PERIOD IS A MID TO UPPER-LEVEL
   LOW WHICH WILL TRACK FROM THE LOWER CO VALLEY SEWD INTO NWRN MEXICO.
   AS THIS OCCURS...AN ASSOCIATED SUBTROPICAL BRANCH JET STREAK WILL
   DEVELOP EWD ACROSS NRN MEXICO WITH ITS EXIT REGION OVERSPREADING THE
   LOWER RIO GRANDE VALLEY TONIGHT.  IN THE LOW LEVELS...A SURFACE
   FRONT WHICH HAS DRIFTED WELL S OF THE GULF COAST INTO THE GOM WILL
   REDEVELOP NWD INTO THE SHELF WATERS AND DEEP S TX BY 08/12Z. 
   
   ...SERN AZ INTO CNTRL/SRN TX TONIGHT...
   
   THE LOW-LEVEL MASS RESPONSE TO THE APPROACHING UPPER LOW AND EXIT
   REGION OF THE SUBTROPICAL JET STREAK WILL FOSTER THE DEVELOPMENT OF
   A SLY LLJ TONIGHT ACROSS SRN INTO CNTRL TX.  THIS WILL HASTEN THE
   NWD FLUX OF AN INCREASINGLY MOIST LOW-LEVEL AIR MASS ABOVE A STABLE
   NEAR-SURFACE LAYER AND BENEATH A PLUME OF STEEPENING MIDLEVEL LAPSE
   RATES OVERSPREADING THE REGION FROM THE WEST.  THIS THERMODYNAMIC
   STRATIFICATION WILL YIELD A WEAKLY UNSTABLE ENVIRONMENT /I.E. MUCAPE
   OF 250-500 J PER KG/ PRIMARILY AFTER 08/06Z.  THIS INSTABILITY WILL
   COMBINE WITH STRENGTHENING LARGE-SCALE FORCING FOR ASCENT AHEAD OF
   THE UPPER LOW FOR ISOLATED TO WIDELY SCATTERED...ELEVATED TSTM
   DEVELOPMENT LATER TONIGHT INTO EARLY TUESDAY.  NO SEVERE WEATHER IS
   ANTICIPATED OWING TO THE WEAK INSTABILITY FORECAST.
   
   ...SRN FL TODAY...
   
   THE PRESENCE OF A WEAK SYNOPTIC FRONT AND DEVELOPING SEA-BREEZE
   CIRCULATIONS WILL FOCUS CONVECTIVE DEVELOPMENT THIS AFTERNOON...SOME
   OF WHICH MAY BE CAPABLE OF ISOLATED LIGHTNING STRIKES. 
   HOWEVER...THE ANTICIPATED AREAL COVERAGE APPEARS TOO LIMITED TO
   INCLUDE A GENERAL TSTM AREA.
