FIRE WEATHER PLANNING FORECAST FOR SOUTHERN NEW ENGLAND
NATIONAL WEATHER SERVICE BOSTON/NORTON MA
407 PM EDT SUN AUG 30 2026
DISCUSSION
MAINLY DRY BUT A BIT COOLER ON MONDAY WITH ONSHORE FLOW
ESPECIALLY ACROSS EASTERN MASSACHUSETTS. HIGH TEMPS WILL BE IN
THE 70S TO NEAR 80 WITH THE COOLEST OF THOSE READINGS ALONG THE
COAST. WINDS WILL BE LIGHT AND VARIABLE...EXCEPT EASTERLY AT 7 TO
13 MPH ALONG THE EASTERN MA COAST. MINIMUM AFTERNOON RELATIVE
HUMIDITY VALUES WILL BE ON THE ORDER OF 50 TO 65 PERCENT...BUT A
BIT HIGHER ACROSS THE CAPE AND ISLANDS.
OUTLOOK...MONDAY NIGHT THROUGH FRIDAY
AN ACTIVE PATTERN WITH UNSETTLED WEATHER AT TIMES IN THE MONDAY
NIGHT THROUGH THURSDAY TIME FRAME. TIMING THE GREATEST RISK FOR
SHOWERS REMAINS DIFFICULT AT THIS POINT. HOWEVER...THE GREATEST
RISK FOR A ROUND OF WIDESPREAD SHOWERS AND A FEW THUNDERSTORMS
APPEARS TO BE MONDAY NIGHT INTO TUESDAY MORNING AND POTENTIALLY
LATER WEDNESDAY INTO PART OF THURSDAY. THE TIMING THOUGH MAY NEED
TO BE REFINED.
DRIER AND PLEASANT WEATHER LOOKS TO DOMINATE FRIDAY INTO THE
HOLIDAY WEEKEND. HIGHS IN THE 70S TO NEAR 80 WITH COMFORTABLE
HUMIDITY OVER THIS TIME.
