Regional Weather Story
National Weather Service Boston/Norton MA
405 PM EDT Fri May 25 2018

Gusty southwest winds escorted an unseasonably warm airmass across
the region this afternoon. Highs reached into the mid and upper 80s,
but along the south coast, Cape Cod and islands, the onshore winds
capped highs in the low 60s to low 70s.

It will be clear tonight with temperatures falling back into the mid
50s to low 60s. Winds will continue out of the southwest but
diminish to 10 to 20 mph. Areas of fog and low clouds might form
again along the south coast, Cape and islands, as they did last

On Saturday, unseasonable warmth will continue with highs topping
out in the mid 80s to 90 degrees. But it will be cooler once again
along the south coast due to onshore winds, where highs will only
top out in the mid 60s to mid 70s. Most of Saturday will be dry,
however a back door cold front will move south through Southern New
England in the late afternoon and evening, triggering scattered
showers and thunderstorms.

This front will bring a noticeable change in air mass as it sags
south Saturday night and stalls over the ocean south of New England
on Sunday. Behind it a cool and damp maritime airmass will settle
over the region on east to northeast winds. In addition, expect
scattered rain Saturday night and Sunday. Highs on Sunday will only
rise into the mid 50s to low 60s.

Cool conditions will continue across the east coast on Monday, where
highs will only be in the upper 50s to mid 60s. Across the interior
it will warm into the upper 60s to mid 70s. The chance for rain
diminishes on Monday due to the front sagging further southeast.

Looking ahead, warm and dry conditions will return for Tuesday and
Wednesday as high pressure builds over New England. Warm conditions
will prevail into Thursday and Friday as the high shifts southeast
of our region. Meanwhile, some remnants of tropical moisture may
head our way for later in the work week.
