Boston is starting Thursday under clouds near the upper 50s, but the gray is temporary. Skies should turn sunny as temperatures climb to around 60 degrees, giving the city one calm outdoor window before rain and a sharp weekend cooldown.

Sunny Thursday Gives Boston A Brief Break

Thursday stays dry, with north winds running from 2 to 14 mph and gusts as high as 28 mph early before easing later in the day. Temperatures should peak near 60, then fall to around 47 Thursday night under partly cloudy skies.

Friday brings the bigger weather change. Showers could arrive before 9 a.m., followed by periods of rain and patchy fog through the afternoon, with an 80% chance of precipitation and rainfall totals generally between a tenth and a quarter of an inch, according to the National Weather Service Boston/Norton.

Friday Rain Arrives With Gusty Winds

Friday will be warmer than Thursday, reaching about 68 degrees, but the combination of rain, fog and south winds gusting up to 30 mph could make for a messy commute and a less-than-ideal day for outdoor plans. The latest forecast sharpens the timing of the wet weather described in Hoodline's earlier forecast, with rain now expected to be most persistent from Friday morning into the afternoon.

Friday night stays unsettled, with rain showers likely, patchy fog and temperatures dropping to around 44 degrees. Winds shift west and remain gusty, with peak gusts near 28 mph.

Saturday Brings A Fast Fall Reset

Saturday starts with a chance of early showers before turning partly sunny, but the temperature may struggle to reach 50 degrees. Northwest winds of 16 to 20 mph could gust as high as 31 mph, making it feel colder, while Saturday night falls to around 36 under mostly clear skies.

There are no land-based watches or warnings listed for Boston, though marine conditions will be rougher. A Small Craft Advisory remains in effect Thursday afternoon, and a Gale Watch covers Friday evening through Saturday evening for much of the nearby coastal waters.

Sunshine Returns For The Start Of Next Week

Sunday looks like the cleanest day of the weekend, with sunny skies, lighter west winds and a high near 54 degrees. Monday stays mild near 59 with a slight chance of showers, followed by mostly sunny skies and a high near 61 Tuesday.
