...SYNOPSIS...
CONTINENTAL AIR MASS HAS PENETRATED WELL SWD INTO THE GULF OF MEXICO
 THIS WEEKEND...IN WAKE OF SYSTEM NOW LIFTING NEWD INTO THE
NORTHEASTERN U.S.  THIS HAS INHIBITED LOW LEVEL MOISTURE RETURN AND
WILL LIMIT OVERALL POTENTIAL FOR DEEP MOIST CONVECTION THROUGH THE
PERIOD.  EXCEPTIONS WILL BE OVER PORTIONS OF THE CENTRAL/SRN
ROCKIES...SRN PLAINS AND THE NORTHEAST WHERE MOIST CONVECTION
INCLUDING A FEW THUNDERSTORMS ARE EXPECTED.

...FOUR CORNERS REGION...
COMPACT UPPER LOW DIGGING SSEWD ACROSS THE GREAT BASIN THIS MORNING
WILL AID IN DESTABILIZATION OVER THE FOUR-CORNERS REGION AND SRN
CO/NRN NM THIS AFTERNOON.  POCKET OF COLD MID LEVEL AIR AND
INCREASING LARGE SCALE ASCENT WITHIN CYCLONIC SIDE OF MID/UPPER JET
SHOULD ALLOW WEAK INSTABILITY AND ISOLATED THUNDERSTORMS TO DEVELOP
WITH AFTERNOON HEATING.

...SRN PLAINS...
AHEAD OF GREAT BASIN UPPER LOW...SSWLY LLJ WILL STEADILY INCREASE
ACROSS THE SRN PLAINS. FORECAST SOUNDINGS AFTER 06Z SUGGEST
MOISTENING ABOVE STABLE BOUNDARY LAYER WILL BE SUFFICIENT FOR WEAK
ELEVATED INSTABILITY...GIVEN EXPECTED STEEP MID LEVEL LAPSE RATES. 
COMBINATION OF DESTABILIZATION AND INCREASING VERTICAL MOTION WILL
RESULT IN GREATER PROBABILITIES OF CONVECTION...INCLUDING A FEW
EMBEDDED THUNDERSTORMS.

...NORTHEAST...
FORECAST SOUNDINGS OVER THIS REGION SUGGEST NEUTRAL TO VERY WEAK
INSTABILITY...ELEVATED ABOVE SHALLOW STABLE LAYER...WILL DEVELOP
TODAY WHICH MAY BE SUFFICIENT FOR A FEW THUNDERSTORMS. THUNDERSTORM
PROBABILITIES WILL BE HIGHER NEARER THE COAST.
