   ...SYNOPSIS...
   LARGE / NEGATIVELY-TILTED MID-LEVEL TROUGH IS FORECAST TO EXTEND
   FROM THE PAC NW SEWD INTO THE SRN HIGH PLAINS AT THE START OF THE
   PERIOD.  WITH TIME...CLOSED LOW IS FORECAST TO DEVELOP OVER THE SRN
   ROCKIES AND THEN SHIFT EWD INTO THE SRN HIGH PLAINS BY THE END OF
   THE PERIOD.  STRONG / DEEP-LAYER WLY FLOW IS FORECAST ACROSS THE
   SRN ROCKIES AT THE START OF THE PERIOD...AND IS FORECAST TO SPREAD
   EWD ACROSS TX WITH TIME.  MEANWHILE...FLOW ALOFT IS EXPECTED TO
   REMAIN MORE SLY NORTH OF THE RED RIVER ALONG ERN FRINGES OF UPPER
   TROUGH / LOW.
   
   AT THE SURFACE...LOW INITIALLY FORECAST ACROSS ERN CO / WRN KS IS
   FORECAST TO DEEPEN / SHIFT SLIGHTLY SWD WITH TIME...BECOMING
   CENTERED OVER THE OK PNHDL BY THE END OF THE PERIOD.  A DRYLINE
   INITIALLY OVER W CENTRAL TX / THE ERN TX PANHANDLE IS FORECAST TO
   SURGE EWD THROUGH CENTRAL TX DURING THE DAY WITH THE EWD ADVECTION
   OF DRY AIR ALOFT -- FOLLOWED EVENTUALLY BY A COLD FRONT WHICH
   SHOULD MOVE INTO CENTRAL TX BY THE END OF THE PERIOD.
   
   ...SRN PLAINS...
   LOW-LEVEL MOIST ADVECTION ACROSS CENTRAL AND ERN TX / OK WILL BE
   UNDERWAY AT THE START OF THE PERIOD ON SLY / SELY FLOW AHEAD OF
   SURFACE DRYLINE.  BY AFTERNOON...DEWPOINTS ARE FORECAST TO INCREASE
   INTO THE LOW 60S OVER OK AND LOW TO MID 60S ACROSS ERN TX BENEATH
   STEEP LAPSE RATES FORECAST TO BE IN PLACE OVER THIS REGION...
   YIELDING MEAN-LAYER CAPE AROUND 1000 J/KG.  
   
   STRONG LOW-LEVEL CONVERGENCE ALONG DRYLINE COMBINED WITH STRONGLY
   DIFFLUENT FLOW ALOFT ACROSS THIS REGION WILL YIELD SUFFICIENT UVV
   FOR THUNDERSTORM DEVELOPMENT BY EARLY AFTERNOON FROM NRN / NERN TX
   INTO CENTRAL AND ERN OK.  LOW-LEVEL WINDS ARE EXPECTED TO VEER WITH
   HEIGHT ACROSS THE REGION...ALTHOUGH MORE MERIDIONAL FLOW IS
   EXPECTED ALOFT FROM CENTRAL OK INTO SRN KS.  THIS COMBINED WITH
   STEEPER MID-LEVEL LAPSE RATES ACROSS THIS REGION SUGGEST THE
   GREATEST SEVERE THREAT WILL LIKELY BE LARGE HAIL ALONG WITH LOCALLY
   DAMAGING WINDS. 
   
   IN ADDITION TO THE HAIL / WIND THREAT...GREATEST SUPERCELL TORNADO
   THREAT APPEARS TO EXIST ACROSS E TX INTO SERN OK DURING THE DAY --
   AND PERHAPS EWD INTO SWRN AR / NWRN LA THROUGH THE EVENING. 
   GREATER LOW-LEVEL MOISTURE IS FORECAST ACROSS THIS REGION
   SUGGESTING SOMEWHAT LOWER CLOUD BASES ACROSS THIS REGION...AND MORE
   WLY WINDS ALOFT SHOULD PROVIDE A MORE FAVORABLE / DEEPLY-VEERING
   WIND PROFILE.
   
   ...CENTRAL PLAINS...
   DEEP-LAYER SELY WIND FIELD IS FORECAST FROM KS NWD INTO NEB THIS
   PERIOD NORTHEAST OF DEVELOPING MID-LEVEL LOW.  HOWEVER...WIND FIELD
   WILL LIKELY BE STRONG ENOUGH FOR AT LEAST MULTICELL STORM
   ORGANIZATION.  STORMS ARE FORECAST TO DEVELOP ACROSS THIS REGION
   DURING THE AFTERNOON IN MARGINALLY-UNSTABLE AIRMASS IN BROAD REGION
   OF UVV NORTHEAST OF UPPER VORT MAX MOVING NWD ACROSS THE CENTRAL /
   SRN HIGH PLAINS.  LARGE HAIL WILL LIKELY BE THE PRIMARY SEVERE
   THREAT GIVEN STEEP LAPSE RATES / COOL TEMPERATURES ALOFT...ALTHOUGH
   RELATIVELY DRY AIR AT LOW-LEVELS SUGGESTS A THREAT FOR LOCALLY
   DAMAGING WINDS AS WELL.
   
   ...GULF COAST INTO FL...
   STRONG VORT MAX IS INDICATED ATTM ACROSS THE CENTRAL GULF -- AND
   THIS FEATURE IS FORECAST TO MOVE SLOWLY NEWD INTO THE ERN GULF
   COASTAL REGION DURING THE DAY 2 PERIOD.  MID-LEVEL LAPSE RATES IN
   THE 6 TO 6.5 C/KM RANGE COMBINED WITH SURFACE DEWPOINTS IN THE LOW
   60S WILL RESULT IN MARGINAL INSTABILITY SUPPORTIVE OF WIDESPREAD
   THUNDERSTORMS AS VORT MAX APPROACHES.  MODERATE / WLY DEEP-LAYER
   WIND FIELD IS FORECAST...WHICH SUGGESTS PRIMARY SEVERE THREATS WILL
   BE MARGINALLY-SEVERE HAIL AND LOCALLY DAMAGING WINDS.
