FIRE WEATHER PLANNING FORECAST FOR SOUTHERN NEW ENGLAND
NATIONAL WEATHER SERVICE BOSTON/NORTON MA
407 PM EDT THU AUG 27 2026
DISCUSSION
A FRONTAL SYSTEM APPROACHES LATE TODAY WITH THE POTENTIAL FOR
SCATTERED SHOWERS AND THUNDERSTORMS. THE GREATEST RISK FOR
WESTERN MASSACHUSETTS AND CONNECTICUT. THIS FRONT SLOWS NEAR OUR
REGION FRIDAY WITH PERIODS OF SHOWERS AND A FEW THUNDERSTORMS
POSSIBLE.
MINIMUM RELATIVE HUMIDITY VALUES TODAY EXPECTED TO RANGE BETWEEN
50 AND 70 PERCENT, AND BETWEEN 65 TO 85 PERCENT FRIDAY. HIGHER
VALUES TOWARDS THE OUTER CAPE AND ISLANDS.
OUTLOOK...FRIDAY NIGHT THROUGH TUESDAY
AT THE MOMENT THE WEEKEND LOOKS MAINLY DRY WITH AN OUTSIDE CHANCE
FOR SOME ADDITIONAL RAINFALL SUNDAY. A BACKDOOR COLD FRONT EARLY
NEXT WEEK MAY TRIGGER ADDITIONAL SHOWERS, AND PERHAPS A FEW
THUNDERSTORMS TUESDAY AS WELL.
