   ...SRN PLAINS TO THE LOWER OH VALLEY...
   A SURFACE RIDGE EXTENDING WWD FROM THE OH VALLEY/MID-ATLANTIC
   STATES INTO THE SRN PLAINS WILL MOVE EWD TODAY AS A LOW-LEVEL
   TROUGH CONTINUES TO DEVELOP IN LEE OF THE ROCKIES BENEATH UPPER
   LEVEL ZONAL FLOW.  
   
   ONGOING ISOLATED ELEVATED THUNDERSTORMS OVER N CENTRAL OK TO THE KS
   BORDER DEVELOPED WITHIN MOIST ISENTROPIC ASCENT IN THE 850-750 MB
   LAYER ON THE NOSE OF A 30 KT SSWLY LLJ PER AREA VADS/PROFILERS. 
   THIS CONVECTION SHOULD SPREAD EWD ON THE NOSE OF A VEERING LLJ WITH
   SOME INTENSIFICATION POSSIBLE THIS EVENING OVER CENTRAL/SRN MO...
   AS A WEAK UPPER LEVEL SHORT WAVE TROUGH TRACKS ESEWD FROM THE
   CENTRAL ROCKIES.  CONVECTION SHOULD MOVE INTO THE LOWER OH VALLEY
   OVERNIGHT.  
   
   FARTHER SW...EXPECT LOW-LEVELS TO DESTABILIZE BY THIS AFTERNOON AS
   BOUNDARY LAYER MOISTURE RETURNS NWD FROM THE RIO GRANDE VALLEY WITH
   AFTERNOON SURFACE DEWPOINTS IN THE LOWER TO MID 50S OVER W/NW TX
   AND AROUND 60 OVER CENTRAL TX.  STEEP MID-LEVEL LAPSE RATES /7.5-8
   C/KM PER 12Z SOUNDINGS OVER WRN TX/ ASSOCIATED WITH ELEVATED MIXED
   LAYER ARE EXPECTED TO KEEP THE SRN PLAINS CAPPED THROUGH MUCH OF
   THE DAYLIGHT HOURS.  HOWEVER...IF A THUNDERSTORM CAN DEVELOP WITHIN
   THIS ENVIRONMENT...MODEST DEEP LAYER SHEAR AND SBCAPE AROUND 1500
   J/KG OVER W/NW TX WOULD SUPPORT AN ISOLATED SEVERE STORM WITH HAIL.
   A SWLY 25-30 KT LLJ IS EXPECTED TO DEVELOP OVERNIGHT FROM W/NW TX
   INTO CENTRAL OK...SUPPORTING ELEVATED CONVECTION WITH A CONTINUED
   THREAT FOR ISOLATED HAIL.  THEREFORE...HAVE KEPT LOW PROBABILITIES
   FOR HAIL FROM W/NW TX INTO OK FOR THIS FORECAST PERIOD. 
   
   ...CAROLINA COASTAL PLAINS...
   SHORT WAVE TROUGH...CURRENTLY OVER WV SWD TO THE SRN APPALACHIANS
   PER WV IMAGERY...WILL WEAKEN AS IT MOVES THROUGH THE MID-ATLANTIC
   REGION TODAY AND THEN OFFSHORE AFTER 00Z.  A SURFACE WAVE IS
   PROGGED TO MOVE NEWD ALONG A COASTAL TROUGH FROM THE SC COAST THIS
   MORNING TO THE NC COAST THIS AFTERNOON.  06Z ETA CONTINUES TO
   APPEAR TOO AGGRESSIVE WITH BRINGING MOISTURE INLAND ALONG THE
   COASTAL CAROLINAS TODAY...WITH THE 09Z RUC MORE IN AGREEMENT WITH
   EARLY MORNING SURFACE DEWPOINTS OVER THIS AREA.  EXPECT WEAK
   INSTABILITY /SBCAPE VALUES AOB 500 J/KG/ TO DEVELOP BY LATE MORNING
   ASSOCIATED WITH SURFACE DEWPOINTS IN THE LOWER TO MID 50S.  AS
   LARGE SCALE ASCENT MOVES OVER THIS REGION WITH THE SHORT WAVE
   TROUGH...CONVECTION SHOULD DEVELOP INVOF THE COASTAL TROUGH BY LATE
   MORNING AND CONTINUE INTO THE MID-AFTERNOON BEFORE THE UPPER TROUGH
   MOVES OFFSHORE.  COOL MID-LEVEL TEMPERATURES AND SUFFICIENT DEEP
   LAYER SHEAR WILL SUPPORT HAIL...BUT WEAK INSTABILITY SHOULD LIMIT
   THE SEVERE THREAT.
