Boston Weather forecast: boston weather storm maps show Friday impacts

A new winter storm will arrive Friday afternoon, bringing cold rain, freezing rain, sleet and a wintry mix that will transition to snow in places; boston weather conditions are expected to worsen during the afternoon and evening, creating iffy road conditions ahead of weekend travel.

Boston Weather Friday storm maps

The region’s active pattern resumes Friday as a system pushes east with an initial warm front ahead of the core and a chance of a secondary low forming over the ocean that could boost precipitation at times. Precipitation will intensify through the afternoon and evening and then slowly taper off overnight.

Southern New England should expect a start of wintry mix and cold rain, especially by the coast and south of the Massachusetts Turnpike; the rain-snow line is forecast to shift southward Friday evening into the night, at which point accumulation becomes more likely. Boston is projected to total between 1 and 3 inches of snow by noon Saturday, with higher amounts north of the city.

Timing and likely travel impacts

Precipitation will pick up Friday afternoon and become heavier into the evening, making roads slippery and travel conditions uncertain through the night. Northern New England will see snow from the start of the storm, with broader travel impacts expected there earlier in the event.

The Friday system is expected to ease overnight, but weekend travel will remain subject to the next system’s timing and track.

boston weather weekend nor'easter

A separate nor'easter is likely to affect the region late Sunday into Monday, with meteorologists warning of heavy snow and blizzard-like conditions in spots. The Cape and Islands, the South Coast and the South Shore are forecast to be hardest hit, where more than a foot of snow is possible in southeastern parts of Massachusetts.

Boston’s odds of receiving 6 inches or more look decent for the Sunday night through Monday period; some forecast runs show a narrower 4–8 inch range for the Boston area while heavier totals are possible farther southeast. Winds in the 40 to 50 mph range are expected, with increasing confidence in widespread 50-plus mph gusts on Cape Cod and the Islands.

A "Winter Storm Watch" has been issued for the Cape, Islands and South Coast. High Wind Watches are in place for the Cape and Islands, with Storm Watches posted for coastal waters; offshore seas could reach around 25 feet. Damaging winds could bring down trees and power lines, so power outages are possible. Snow is expected to begin Sunday night, peak Monday morning, then taper later Monday.

• Friday: wintry mix turning to snow; Boston 1–3 inches by noon Saturday (approx. ).
• Weekend: nor'easter likely Sunday night–Monday; Cape/Islands >1 foot possible.

If the Sunday–Monday storm shifts northwest, the current Winter Storm Watch may be expanded to include more of eastern Massachusetts. Forecast models and watch status should be monitored closely as timing and track evolve.
