   ...THERE IS A SLGT RISK OF SVR TSTMS OVER THE CNTRL AND SRN HI
   PLNS...
   
   ...SYNOPSIS...
   FLAT RIDGE WILL REMAIN IN PLACE FROM THE SRN PLNS TO S ATLANTIC CST
   ON SATURDAY...WHILE MODERATE WLY FLOW CONTINUES OVER THE NRN HALF OF
   THE NATION.  A SPEED MAX IN CONFLUENT JET PATTERN OVER SRN ONTARIO
   WILL CROSS QUEBEC AND NRN NEW ENG.  IN THE WEST...A PART OF
   SHORTWAVE TROUGH NOW OVER WA SHOULD SHEAR E ACROSS THE NRN RCKYS AND
   REACH THE NRN HI PLNS BY 12Z SUNDAY.
   
   ...CNTRL/SRN HI PLNS...
   SURFACE ANTICYCLONE DEVELOPING SWD ACROSS THE PLNS DURING THE NEXT
   36 HRS WILL SHUNT BOUNDARY LAYER MOISTURE W TO THE FOOTHILLS OF THE
   CNTRL AND SRN RCKYS.  DESPITE ABSENCE OF ANY IDENTIFIABLE LARGE
   SCALE FORCING...COMBINATION OF WEAK UPSLOPE COMPONENT TO LOW LEVEL
   FLOW...MODERATE MOISTURE AVAILABILITY AND STEEP MID LEVEL LAPSE
   RATES SHOULD SUPPORT SCATTERED THUNDERSTORM DEVELOPMENT WITH
   AFTERNOON HEATING FROM CNTRL/ERN WY SWD INTO ERN CO AND NM.
   
   AMPLE /40-50 KT/ DEEP WLY SHEAR...ASSOCIATED WITH THE SRN EDGE OF
   THE WLYS...WILL BE PRESENT TO SUPPORT SUPERCELLS WITH A THREAT FOR
   LARGE HAIL/LOCALLY DAMAGING WIND AND PERHAPS A COUPLE TORNADOES IN
   WY AND CO.  THE MAIN LIMITING FACTOR THROUGHOUT THE REGION WILL
   LIKELY BE RELATIVELY NARROW W/E EXTENT OF SURFACE-BASED INSTABILITY
   AXIS.  SOME OF THE CONVECTION MAY CONSOLIDATE INTO AN ELEVATED MCS 
   THAT MOVES E INTO NEB SATURDAY NIGHT...WITH AN ATTENDANT THREAT FOR
   HAIL.
   
   FARTHER S IN NM...EXPECT STORMS TO BE MORE DIURNAL AND PULSE IN
   NATURE...WHERE DEEP SHEAR WILL REMAIN FAIRLY WEAK /AOB 25 KT/.
   
   ...UPPER SOUTH...
   SCATTERED CLUSTERS OF STRONG TO LOCALLY SEVERE STORMS MAY DEVELOP
   WITH DAYTIME HEATING INVOF WEAKENING COLD FRONT OVER THE TN
   VLY...WHERE SURFACE-BASED MLCAPE MAY REACH 3000 J/KG...BUT DEEP
   SHEAR WILL BE WEAK.
   
   ...NEW ENG...
   A FEW STORMS MAY PRECEDE FAST-MOVING IMPULSE CROSSING QUEBEC.  BUT
   WEAK LOW TO MID LEVEL LAPSE RATES AND SHALLOW CONVERGENCE SHOULD
   LIMIT STORM COVERAGE AND INTENSITY DESPITE PRESENCE OF FAVORABLE
   LARGE SCALE ASCENT/DEEP SHEAR.
