LONG RANGE DISCUSSION FOR 0300Z 26 OCT TO 0300Z 29 OCT.
MODEL DISCUSSION: USED GDPS
CONFIDENCE: HIGH
COMMENTS/IMPACTS: ON MONDAY, THE RIDGE CONTINUES TO DROP A LITTLE
 FURTHER SOUTH AND THIS ALLOWS A WEAKENING COLD FRONT OVER QUEBEC TO
 DROP SOUTHWARD INTO NORTHERN NEW BRUNSWICK. MONDAY SHOULD BE A
 NICE DAY WITH PLEASANT TEMPERATURES. THE FRONT MOVES THROUGH MONDAY
 NIGHT WITH CLOUDINESS AND SPOTTY SHOWERS, BUT HAS CLEARED THE AREA
 BY TUESDAY MORNING. TEMPERATURES WILL BE MUCH COOLER TUESDAY AND
 CLOUDY BITS WILL DEVELOP IN THE COOLER FLOW OFF THE GULF OF ST.
 LAWRENCE, BUT THERE IS A CHANCE THE DAY COULD WIND UP MAINLY SUNNY
 IF THE WIND DIRECTION CAN GET A LITTLE MORE NORTHWEST.
  IT CONTINUES SUNNY INTO WEDNESDAY BUT THE FLOW IS STILL COOL AND
 OUT OF THE NORTHWEST. PROGNOS TEMPERATURES ARE ONLY A FRACTION
 HIGHER THAN TUESDAY BUT THE WIND WILL BE LIGHTER, SO IT SHOULD FEEL
 A LITTLE WARMER.
