Boston, MA – Rain soaked pavement, gusty northwest winds and a sharp drop in temperatures could bring a noticeable change to the Boston area heading into the weekend. Friday's rain chances reach 80%, with patchy fog and afternoon temperatures near 68 degrees before colder air moves into eastern Massachusetts. By Saturday night, temperatures are expected to fall near 36 degrees, creating a 32 degree difference from Friday's high. Sunshine returns Sunday, although the morning will remain chilly.
According to the National Weather Service forecast for Boston in Suffolk County, showers are expected Friday, mainly before 4 p.m., with rainfall amounts between one tenth and one quarter of an inch possible. The changing conditions could affect commuters and weekend activities throughout the Boston metropolitan area, particularly as winds strengthen Saturday.
Friday Rain Brings Wet Roads and Patchy Fog Friday begins with patchy fog before 8 a.m., followed by another period after 9 a.m. Showers are expected during the day, with an 80% precipitation probability and temperatures climbing near 68 degrees. Southeast winds of 8 to 13 mph could gust as high as 29 mph, creating breezy conditions as rainfall moves through the city.
Additional showers remain likely Friday night, mainly between 9 p.m. and 2 a.m. The National Weather Service places the precipitation probability at 70%, with temperatures falling near 44 degrees. Southwest winds around 10 mph are expected to turn northwest after midnight, with gusts potentially reaching 25 mph as colder air begins arriving.
Drivers traveling along Interstate 93, Interstate 90, Route 1 and the Massachusetts Turnpike could encounter wet pavement and reduced visibility during periods of rain and fog. The forecast does not identify specific roadway closures or confirmed travel delays, but commuters should allow for changing conditions, particularly Friday morning and afternoon.
Saturday Winds Bring a Noticeably Colder Weekend Saturday marks a substantial shift in temperatures, with afternoon highs expected to reach only 50 degrees. That represents an 18 degree decline from Friday's projected high, despite skies becoming partly sunny after a slight chance of early showers.
A 30% chance of precipitation remains before 7 a.m. Saturday, followed by improving conditions. Northwest winds around 14 mph could gust as high as 31 mph, making outdoor conditions feel colder than the afternoon temperature alone suggests.
Saturday night brings mostly clear skies and temperatures falling near 36 degrees. The difference between Friday's high of 68 degrees and Saturday night's low reaches 32 degrees across the two day period. Although the forecast approaches freezing, the supplied information does not establish a frost advisory or freeze warning for Boston.
Residents attending evening sporting events, waterfront activities or outdoor gatherings may want heavier jackets. The combination of lower temperatures and gusty winds could make exposed areas near Boston Harbor feel particularly chilly.
Sunday Sunshine Returns Before Gradual Warming Sunday, Oct. 18, brings a more favorable outlook, with sunny skies and afternoon temperatures recovering near 55 degrees. Northwest winds of 6 to 8 mph are expected, considerably lighter than Saturday's strongest forecast gusts.
Sunday night remains mostly clear, with temperatures falling near 42 degrees. The warming trend continues Monday, when sunshine returns and temperatures reach approximately 60 degrees.
By Tuesday, Boston could reach 62 degrees under mostly sunny skies, followed by another sunny day Wednesday with a high near 58 degrees. The supplied forecast does not indicate additional significant rainfall after Saturday morning.
For residents planning weekend activities, Saturday's gusty winds and colder temperatures remain the primary concerns before more comfortable conditions return Sunday afternoon.
