   ...SYNOPSIS...
   UPPER RIDGE WILL AMPLIFY OVER THE GRT BASIN/NRN RCKYS ON MONDAY IN
   WAKE OF STRONG SHORTWAVE IMPULSE NOW OVER SRN SASKATCHEWAN.  THE
   LATTER SYSTEM SHOULD WEAKEN AS IT MOVES FROM WRN ONTARIO/NE MN INTO
   SRN QUEBEC DURING THE PERIOD.  FARTHER E...EXPECT RIDGE TO PERSIST
   OVER THE NW ATLANTIC AS T.S. GASTON SLOWLY INCREASES FORWARD SPEED
   AND MOVES NE ACROSS THE LWR CHESAPEAKE BAY REGION /SEE TPC FCSTS FOR
   DETAILS/.
   
   TRAILING FRONTAL ZONE ASSOCIATED WITH DISTURBANCE NOW OVER
   SASKATCHEWAN WILL BEGIN TO LIFT NEWD AS A WARM FRONT ACROSS THE NRN
   PLNS/UPR MS VLY DURING THE PERIOD.  WITH THE EXCEPTION OF THAT
   FEATURE...SURFACE BOUNDARIES WILL REMAIN WEAK.
   
   ...SRN/CNTRL HI PLNS...
   STRONG INSTABILITY /MLCAPE TO 2000 J PER KG/ WILL DEVELOP OVER THE
   MOUNTAINS OF CO/NM AND THE ADJACENT HI PLNS ON MONDAY AS SURFACE
   HEATING DESTABILIZES AXIS OF RESIDUAL BOUNDARY LAYER MOISTURE
   ASSOCIATED WITH WEAKENING FRONT NOW OVER THE SRN PLNS. COMBINATION
   OF STEEP LOW TO MID LEVEL LAPSE RATES AND VERY WEAK SHEAR WILL FAVOR
   SCATTERED AFTERNOON/EARLY EVENING PULSE STORMS...SOME OF WHICH MAY
   BRIEFLY POSE A THREAT FOR DOWNBURSTS/SEVERE HAIL.
   
   ...NRN PLNS/UPR MS VLY...
   AMPLIFICATION OF WRN RIDGE AND DIURNAL PROCESSES EXPECTED TO RESULT
   IN STRENGTHENING OF LOW LEVEL JET/WARM ADVECTION OVER THE ERN DAKS
   AND MN MONDAY NIGHT.  THIS MAY RESULT IN THE DEVELOPMENT OF
   SCATTERED ELEVATED THUNDERSTORMS AS WNWLY MID LEVEL FLOW MAINTAINS
   AXIS OF STEEP MID LEVEL LAPSE RATES OVER REGION.  SPARSE MOISTURE
   SHOULD LIMIT MAGNITUDE OF ELEVATED CAPE...AND THE LIKELIHOOD FOR
   SEVERE HAIL.
   
   ...NRN WI/NRN MI...
   WITH SHORTWAVE IMPULSE NOW OVER SASKATCHEWAN EXPECTED TO LIFT ENE
   ACROSS SRN ONTARIO THIS PERIOD...POTENTIAL FOR STRONG STORMS SHOULD
   REMAIN MINIMAL OVER NRN PORTIONS OF WI/MI ON MONDAY.  NEVERTHELESS
   ...DAYTIME HEATING BENEATH LINGERING PATTERN OF SEASONABLY COOL AND
   CYCLONIC 500 MB FLOW MAY YIELD A FEW CELLS WITH SMALL HAIL.
