   ...WEST...
   A STRONG PACIFIC IMPULSE WAS COMING ASHORE NORTH OF SFO. THIS SYSTEM
   WILL DIG INTO THE FOUR CORNERS REGION THROUGH LATE THURSDAY NIGHT
   WITH 60-90M 500MB HEIGHT FALLS SPREADING ACROSS AZ AND NM BY EARLY
   FRIDAY. DESPITE STRONG ASCENT ASSOCIATED WITH DPVA AND LOW STATIC
   STABILITY...IT APPEARS THAT BEST CHANCES FOR WIDELY SCATTERED TSTMS
   WILL BE EARLY IN THE PERIOD ACROSS PORTIONS OF CNTRL AND ERN CA AND
   PERHAPS INTO NV. FAVORABLE UPPER DYNAMICS AND LOW LEVEL OROGRAPHIC
   FORCING COUPLED WITH SUFFICIENT MOISTURE AND COLD MID LEVEL TEMPS
   SHOULD SUPPORT A FEW TSTMS THROUGH THIS AFTERNOON OVER PARTS OF
   THESE AREAS. FARTHER SOUTH AND EAST...LIMITED MOISTURE AND
   WARMER/MARGINAL EQUILIBRIUM TEMPERATURES APPEAR TO NEGATE LIGHTNING
   POTENTIAL WITH ANY CONVECTION THAT DEVELOPS.
   
   ...NORTHEAST...
   A VERY STRONG UPPER TROUGH AND ASSOCIATED DEEP SURFACE CYCLONE WILL
   LIFT RAPIDLY NEWD FROM THE MID ATLANTIC REGION THROUGH NEW ENGLAND.
   INTENSE WARM/MOIST CONVEYOR BELT WITHIN THE ERN/NERN QUADRANT OF
   THIS SYSTEM WILL BE POWERED BY A 70-80KT LOW LEVEL JET WHICH WILL
   TRANSITION FROM LONG ISLAND...TO SERN NEW ENGLAND...TO THE GULF OF
   MAINE DURING THE PERIOD. FORCING FOR ASCENT ON THE NOSE OF THIS JET
   WILL BE INTENSE BUT THE BEST CHANCE FOR TSTMS WILL LIKELY REMAIN
   NEAR OR JUST OFFSHORE WHERE GREATER INSTABILITY WILL RESIDE NEAR THE
   GULF STREAM CURRENT.
