DECENT AMOUNT OF HOLES IN THE CLOUD FIELD GIVING A MIX OF SUN AND

THE TROUGH. SUNNY SKIES FRIDAY. MODERATE TO STRONG SW TO W WINDS
EXPECTED DURING DAYTIME HOURS TODAY AND FRIDAY. MODELS WERE A BIT ON
THE COOL SIDE WITH DAYTIME HIGH TEMPS THURSDAY, SO I ADDED A COUPLE

CONFIDENCE: MEDIUM TO HIGH.
COMMENTS/IMPACTS: MODELS IN GOOD AGREEMENT FOR SATURDAY WITH WARM
FRONT SLIDING INTO REGION GIVING PERIODS OF RAIN.
ON SUNDAY LOW PRESSURE SYSTEM MOVING INTO GULF OF ST LAWRENCE GIVING
STRONG WINDS AND CHANCE OF SHOWERS. GDPS IS MORE ORGANIZED WITH
ASSOCIATED COLD FRONT THAN OTHER GUIDANCE FOR SUNDAY. GDPS WOULD
SUGGEST MORE SHOWERS THAN OTHER GUIDANCE. I REJECTED THE GDPS
HANDLING OF SHOWERS SUNDAY. RIDGE MOVES IN FOR MONDAY.
