   ...CENTRAL HIGH PLAINS TO ERN SD/SW MN...
   THUNDERSTORMS PERSIST THIS MORNING OVER NE SD NEAR A WEAK SURFACE
   LOW...AND ACROSS NE NEB WHERE A NWD MOVING OUTFLOW BOUNDARY AND WAA
   ON THE NOSE OF A WARM ELEVATED MIXED LAYER COINCIDE.  THOUGH THE
   OVERNIGHT MCS/S IN ERN NEB/WRN IA/NE KS/NW MO HAVE DEPLETED
   INSTABILITY OVER MUCH OF THE SAME AREA...A POOL OF RICHER MOISTURE/
   STRONG INSTABILITY REMAINS ACROSS ERN SD/SW MN TO THE N OF THE
   AREAS IMPACTED BY THE OVERNIGHT STORMS.  STORMS MAY INCREASE IN
   COVERAGE/INTENSITY BY EARLY AFTERNOON AS DAYTIME HEATING
   DESTABILIZES THE LOW LEVELS...AND A WEAK MID-UPPER SPEED MAX MOVES
   NEWD FROM NEB TO MN.  THE STRONG INSTABILITY /MUCAPE IN EXCESS OF
   3000 J/KG/ WILL SUPPORT A FEW SEVERE STORMS THROUGH THE AFTERNOON
   ACROSS ERN SD/WRN MN...WITH LARGE HAIL AND DAMAGING WINDS THE MAIN
   THREATS.
   
   FARTHER S AND W...A WELL-DEFINED OUTFLOW BOUNDARY STRETCHES
   DIAGONALLY FROM SE KS NWWD TO A SURFACE LOW W OF MCK.  THE
   CONVECTION DRIVING THE OUTFLOW IN ERN KS/WRN MO SHOULD MOVE E/SEWD
   AND GRADUALLY WEAKEN LATER TODAY AS THE LOW-LEVEL JET REFOCUSES
   FARTHER TO THE W/NW OF THIS AREA.  MEANWHILE...A STRONG CAP IS
   PRESENT OVER THE WARM SECTOR IN KS /TEMPERATURES OF 15-23 C IN THE
   800-700 MB LAYER/...WHERE CONVECTIVE TEMPERATURES EXCEED 100 F.  IT
   APPEARS THAT THE OUTFLOW BOUNDARY MAY RETREAT NWD INTO NEB BY LATE
   AFTERNOON/TONIGHT AS LOW CLOUDS DIMINISH...AND THETA-E ADVECTION
   ABOVE THE SHALLOW OUTFLOW COMBINES WITH DAYTIME HEATING/MIXING TO
   GRADUALLY ERODE THE SURFACE COLD POOL.  
   
   MEANWHILE...THE SURFACE LOW NEAR MCK SHOULD MOVE E/NEWD AND SLOWLY
   WEAKEN TODAY...AS PRESSURE FALLS DEVELOP FARTHER W ACROSS THE
   CENTRAL HIGH PLAINS IN CONJUNCTION WITH SPEED MAXIMA EJECTING NEWD
   TOWARD WY FROM A DEEP TROUGH OVER NV/UT.  THIS SHOULD RESULT IN
   VEERING OF LOW-LEVEL FLOW FROM NLY TO ELY BY LATE AFTERNOON/EVENING
   øACROSS WRN NEB/SE WY.  THE INCREASING ELY FLOW WILL ADVECT
   BOUNDARY
   LAYER DEW POINTS IN THE 50S WWD INTO SE WY... RESULTING IN
   SUFFICIENT DESTABILIZATION FOR SEVERE STORMS BY LATE
   AFTERNOON/EVENING.  EXPECT SEVERE STORMS TO FORM BY 00Z ACROSS SE
   WY AND THEN MOVE EWD INTO AN INCREASINGLY UNSTABLE ENVIRONMENT
   ACROSS WRN/NRN NEB INTO TONIGHT.  FORECAST SOUNDINGS SHOW LARGE
   CURVED HODOGRAPHS WITH 0-6 KM SHEAR IN EXCESS OF 50 KT...AND 0-3 KM
   SRH OF 250-400 M2/S2.  IT APPEARS THE ENVIRONMENT WILL BE FAVORABLE
   FOR SUPERCELLS WITH VERY LARGE HAIL AND DAMAGING WINDS...ALONG WITH
   THE POSSIBILITY OF A FEW TORNADOES.  STORMS WILL LIKELY EVOLVE INTO
   ONE OR MORE MCS/S ACROSS NEB/SRN SD OVERNIGHT.
   
   ...W TX/ERN NM AREA...
   12Z SOUNDINGS FROM MAF/AMA REVEAL AFTERNOON CONVECTIVE TEMPERATURES
   IN THE RANGE OF 95-100 F...WITH STEEP MID LEVEL LAPSE RATES AND THE
   POTENTIAL FOR SBCAPE VALUES OF 1500-2500 J/KG.  EXPECT WIDELY
   SCATTERED/SCATTERED THUNDERSTORMS TO DEVELOP BY LATE AFTERNOON
   INVOF THE TX/NM BORDER WHERE HOT TEMPERATURES/DEEP MIXING ERODES
   THE CAP FROM BELOW...AND WHERE THE NW EDGE OF A MID LEVEL MOISTURE
   PLUME REDUCES DRY ENTRAINMENT.  THE MODERATE INSTABILITY...IN
   COMBINATION WITH MODEST DEEP LAYER SHEAR AND INVERTED-V
   PROFILES...SHOULD SUPPORT A FEW STORMS WITH LARGE HAIL AND HYBRID
   MICROBURSTS LATE THIS AFTERNOON/EVENING. 
   
   ...INTERIOR NEW ENGLAND...
   A CLOSED MID LEVEL LOW IS DRIFTING SLOWLY ENEWD TO THE S OF NOVA
   SCOTIA.  N/NELY MID LEVEL FLOW OF 30-40 KT PERSISTS OVER NEW
   ENGLAND TO THE W OF THIS LOW...ABOVE RESIDUAL BOUNDARY LAYER DEW
   POINTS IN THE 60S.  12Z SOUNDING FROM CAR SUGGESTS THAT SBCAPE
   VALUES COULD EXCEED 1000 J/KG WITH AFTERNOON TEMPERATURES IN THE
   80S WITH WEAK CIN.  THEREFORE...A FEW THUNDERSTORMS MAY DEVELOP
   THIS AFTERNOON FROM CENTRAL MAINE SWWD INTO NH/VT...WITH THE
   POSSIBILITY OF SMALL HAIL AND STRONG OUTFLOW WINDS GIVEN STEEP LOW-
   LEVEL LAPSE RATES AND MODERATE MID LEVEL FLOW/STORM MOTIONS.
