   ...SYNOPSIS...
   
   SPLIT FLOW WILL PREVAIL OVER THE NATION THROUGH FRIDAY. NRN STREAM
   UPPER TROUGH WILL AMPLIFY OVER THE NERN U.S. WHILE ANOTHER STRONG
   IMPULSE MOVES INTO THE NWRN STATES. THE SRN STREAM SHORTWAVE TROUGH
   CURRENTLY OVER SWRN TX WILL MIGRATE INTO S TX FRIDAY AFTERNOON.
   SURFACE LOW WILL LIKELY DEEPEN OVER THE WRN GULF BY FRIDAY EVENING
   AS ASCENT ASSOCIATED WITH SRN STREAM SHORTWAVE BEGINS TO OVERSPREAD
   THIS REGION. THIS LOW WILL SUBSEQUENTLY MOVE NEWD ALONG BAROCLINIC
   ZONE INTO THE CNTRL GULF FRIDAY NIGHT.
   
   
   ...S TX...
   
   STEEP LAPSE RATES AND COOLING MID LEVEL TEMPERATURES WILL ACCOMPANY
   SHORTWAVE TROUGH INTO S TX FRIDAY AFTERNOON. THOUGH LOW LEVEL FLOW
   WILL HAVE SHIFTED TO NLY...REDUCING BOUNDARY LAYER MOISTURE...THE
   BULK OF THE FRONTAL SURGE WILL REMAIN WELL N OF S TX. IF SURFACE
   DEWPOINTS CAN HOLD IN THE UPPER 40S...COLD MID LEVEL TEMPERATURES
   AND STEEP LAPSE RATES WILL BE SUFFICIENT TO SUPPORT MLCAPE FROM 500
   TO 800 J/KG WHERE SURFACE HEATING OCCURS. SCATTERED CONVECTION WILL
   LIKELY DEVELOP DURING THE AFTERNOON IN ASSOCIATION WITH THE VORT MAX
   AS THE BOUNDARY LAYER DESTABILIZES. THERMODYNAMIC PROFILES APPEAR
   SUFFICIENT TO SUPPORT SOME THREAT FOR HAIL BEFORE ACTIVITY DECREASES
   WITH ONSET OF NOCTURNAL COOLING.
   
   
   ...SERN TX THROUGH SRN LA...
   
   LOW LEVEL JET AND ASSOCIATED ISENTROPIC LIFT WILL GRADUALLY WEAKEN
   IN THIS AREA THROUGH EARLY FRIDAY. A FEW SHOWERS AND THUNDERSTORMS
   MAY REMAIN ONSHORE AT THE START OF THE PERIOD BUT DIMINISH SHORTLY
   AFTER. BY AFTERNOON ACTIVITY SHOULD BE FOCUSED MAINLY ON OFFSHORE
   BOUNDARIES.
   
   
   ...SRN FL...
   
   WARM FRONT NOW NEAR CUBA IS FORECAST TO DEVELOP NWD...BECOMING
   ESTABLISHED OVER S FL FRIDAY. INCREASING LOW LEVEL MOISTURE ALONG
   AND S OF THIS BOUNDARY WILL CONTRIBUTE TO SOME DESTABILIZATION. BUT
   INCREASING MIDDLE AND HIGH LEVEL MOISTURE WITHIN THE SRN STREAM WILL
   RESULT IN MOIST PROFILES WITH POOR LAPSE RATES... LIMITING MUCAPE TO
   AOB 500 J/KG. DESTABILIZATION AND LIFT IN VICINITY OF THE BOUNDARY
   AND IMPULSES EMBEDDED WITHIN THE SRN STREAM WILL LIKELY CONTRIBUTE
   TO THE DEVELOPMENT OF SHOWERS AND THUNDERSTORMS OVER S FL DURING THE
   DAY.
