   ...SYNOPSIS...
   A CLOSED-OFF UPPER-LOW OVER WY AT THE BEGINNING OF THE PERIOD WILL
   SHIFT EWD INTO THE NRN PLAINS AND WEAKEN ON DAY 2. IN ADDITION...A
   PROGRESSIVE SHORTWAVE TROUGH WILL MOVE EWD ACROSS NRN CA AND WRN
   ORE. AT THE SFC...A LEE TROUGH WILL ORGANIZE IN THE CNTRL HIGH
   PLAINS AS A PACIFIC COLD FRONT MOVES ONSHORE ALONG THE WEST COAST.
   
   ...W TX/SW OK...
   A BROAD BAND OF LARGE-SCALE ASCENT ASSOCIATED WITH THE CNTRL PLAINS
   TROUGH WILL SPREAD EWD ACROSS W TX FRIDAY AFTERNOON AND INTO CNTRL
   OK FRIDAY NIGHT. THUNDERSTORM DEVELOPMENT APPEARS MOST LIKELY IN THE
   MTNS OF SERN NM AND W TX DURING THE AFTERNOON. AS THE LOW-LEVEL JET
   STRENGTHENS DURING THE EVENING...MOISTURE TRANSPORT WILL RAPIDLY
   INCREASE ACROSS W TX. THIS SHOULD BE ABLE TO RAISE SFC DEWPOINTS
   INTO THE 50S F ACROSS W TX AND INTO THE 40S F AS FAR NWD AS WRN OK.
   CONVECTION WILL SPREAD GRADUALLY EWD DURING THE LATE AFTERNOON AND
   EARLY EVENING HOURS. ALTHOUGH THE INSTABILITY WILL BE
   ELEVATED...LIFT ASSOCIATED WITH THE LOW-LEVEL JET AND SUPPORT FROM
   THE UPPER-TROUGH MAY BE ENOUGH FOR ISOLATED THUNDERSTORMS ACROSS THE
   SERN TX PANHANDLE AND SWRN OK DURING THE EVENING HOURS. 
   
   ...NRN CA/SW ORE...
   STRONG LARGE-SCALE ASCENT ASSOCIATED WITH A PROGRESSIVE UPPER-TROUGH
   WILL CAUSE WIDESPREAD PRECIPITATION TO SPREAD INLAND ACROSS NRN CA
   AND SWRN ORE ON DAY 2. ALTHOUGH INSTABILITY WILL BE WEAK...LOW-LEVEL
   CONVERGENCE ALONG A COLD FRONT...BROADSCALE LIFT AND SFC DEWPOINTS
   IN THE 40S F MAY BE ENOUGH FOR ISOLATED THUNDERSTORMS WITHIN THE
   HEAVY RAINBANDS.
