   ...SYNOPSIS...
   PROGRESSIVE PATTERN OF RECENT DAYS WITH STRONG WNWLY JET OVER SRN
   CANADA WILL BEGIN TO CHANGE TOWARD A MORE HIGHLY AMPLIFIED LARGE
   SCALE REGIME ON THURSDAY...A PATTERN THAT WILL COME FULLY INTO PLACE
   BY THE END OF THE WEEKEND.  POTENT SHORTWAVE TROUGH WHICH WILL CROSS
   THE GRT LKS TODAY SHOULD LIFT NE INTO QUEBEC THIS PERIOD ...WHILE A
   SERIES OF CLOSELY-SPACED SPEED MAXIMA /ASSOCIATED WITH STRONG SYSTEM
   NOW OFF THE BC CST/ DROP SE ACROSS WRN CANADA INTO THE UPR MS VLY. 
   FARTHER S...SEPARATE SRN STREAM/SUBTROPICAL JET EXPECTED TO PERSIST
   FROM THE SWRN U.S. E INTO TX AND THE LWR MS VLY.
   
   ...MID ATLANTIC/NEW ENG...
   A BAND OF EMBEDDED FORCED CONVECTION WILL LIKELY ACCOMPANY COLD
   FRONT CROSSING NRN/WRN NEW ENG ASSOCIATED WITH UPPER SYSTEM LIFTS NE
   INTO QUEBEC.  GIVEN GRADUALLY WEAKENING DEEP SHEAR AND LIMITED
   SURFACE-BASED INSTABILITY...THREAT FOR SEVERE SHOULD BE MINIMAL.
   
   FARTHER S...CONVECTION/STORMS OF A MORE DIURNAL VARIETY WILL
   PROBABLY DEVELOP ALONG AND AHEAD OF SAME FRONT OVER THE MID ATLANTIC
   REGION SWD INTO THE TN VLY.  MEAN WLY FLOW SHOULD KEEP CONVERGENCE
   ALONG THE BOUNDARY WEAK...AND INSTABILITY WILL BE LIMITED BY MEAGER
   BOUNDARY LAYER MOISTURE INFLUX.  NEVERTHELESS...COMBINATION OF
   SURFACE HEATING AND MID LEVEL 30 KT WLY FLOW MAY SUPPORT A FEW
   STRONG AFTERNOON PULSE STORMS WITH GUSTY WINDS OVER PARTS OF
   PA/MD/VA/WV.
   
   ...SWRN U.S./S TX...
   SCATTERED STRONG DIURNALLY-ENHANCED STORMS MAY DEVELOP DURING PERIOD
   OVER PARTS OF TX AND NM...WHERE AMPLE BOUNDARY LAYER MOISTURE WILL
   PERSIST BENEATH MODERATE WLY FLOW ALOFT.  MOST OF THE ACTIVITY
   SHOULD BE TIED TO TERRAIN...WITH THE BIG BEND REGION AND PERHAPS
   PARTS OF SRN NM BEING THE MOST LIKELY AREAS TO SEE DEVELOPMENT. 
   PRESENCE OF WEAK FRONT /TAIL END OF MID ATLANTIC BOUNDARY/ DRIFTING
   SWD INTO REGION MAY ALLOW A FEW STORMS TO DEVELOP EWD INTO CNTRL TX.
    WHILE THIS ACTIVITY MAY MERGE INTO A CLUSTER OR TWO THURSDAY
   EVENING...EXPECTED SHEAR/INSTABILITY SHOULD LIMIT OVERALL STORM
   ORGANIZATION/INTENSITY.
