Boston, Massachusetts — A round of downpours and possible thunderstorms could move across the Boston area on Friday before a powerful cold front sends temperatures tumbling, bringing a windy Saturday and widespread frost by Sunday morning.
The forecast calls for two rounds of rain across southern New England on Friday, October 16. While conditions should turn drier for much of the afternoon, another round of potentially stronger storms is expected during the evening.
Behind the cold front, temperatures will drop sharply, with daytime highs struggling to reach the 50s in many locations on Saturday. By early Sunday, some areas north and west of Boston could see temperatures fall into the 20s, raising concerns about frost and potentially damaging freezes.
Two Rounds of Rain Expected Across the Boston Area
The first round of rain is expected to develop along a warm front, bringing scattered showers and a few heavier downpours to southern New England between 6 a.m. and noon Friday.
Rainfall may vary by location, and some communities could experience brief periods of heavier precipitation. Conditions are then expected to become mostly dry for much of the afternoon.
However, the break in the rain may not last through the evening.
A second round of showers and possible thunderstorms is forecast to arrive along a strong cold front between 6 p.m. and 10 p.m. Friday. This round could bring more intense downpours and stronger wind gusts to parts of the region.
Residents planning to travel Friday evening should keep an eye on changing conditions, particularly if thunderstorms develop along their route.
Severe Weather Risk Could Bring Strong Winds
The Storm Prediction Center has placed parts of the Boston area’s broader region, primarily south of the Massachusetts Turnpike, under a slight risk for severe weather on Friday.
The main concern is the possibility of strong to damaging winds within any thunderstorms that form. Not every community will experience severe weather, and the exact locations of the strongest storms may depend on how the cold front moves through the region.
Even storms that last only a short time can produce sudden wind gusts capable of bringing down branches or scattering unsecured outdoor items.
Residents should monitor weather alerts and updated local forecasts throughout Friday, especially during the evening storm window.
Those planning outdoor activities may want to secure patio furniture, decorations and other loose items before the cold front arrives.
Saturday Will Turn Cold and Windy
Once the front passes, a much colder air mass is expected to settle across Massachusetts and the surrounding region.
Saturday’s high temperatures will remain in the 40s north and west of Boston, while locations closer to the coast may reach only the low 50s.
Strong northwesterly winds will make conditions feel even colder. Gusts of 20 to 40 mph are expected throughout the day, creating a noticeable chill for anyone spending time outdoors.
With the combination of low temperatures and persistent wind, it could feel more like the 30s and 40s in many locations.
People heading outside Saturday should consider wearing warm layers, particularly during the morning and evening hours. The change will be especially noticeable after the warmer conditions preceding the cold front.
Temperatures Could Drop Into the 20s Sunday Morning
The coldest conditions are expected early Sunday, when temperatures are forecast to reach the mid-to-upper 20s in areas north and west of Interstate 495.
Closer to the coast, overnight lows are expected to fall into the low 30s.
These temperatures could support widespread frost and a killing freeze in some locations, potentially affecting gardens, outdoor plants and sensitive vegetation.
Gardeners should consider bringing potted plants indoors and protecting sensitive plants before temperatures fall. Covering vulnerable vegetation may help where frost is expected, although protection becomes less reliable during a hard freeze.
The lowest temperatures are likely to occur away from the immediate coast, where inland communities can cool more efficiently overnight.
What Boston-Area Residents Should Watch Next
The forecast points to a sharp weather transition across eastern Massachusetts and southern New England, beginning with Friday’s showers and thunderstorms before colder air arrives for the weekend.
The most important periods to watch are Friday morning for the first round of rain, Friday evening for potential thunderstorms, Saturday for strong winds and early Sunday for frost and freezing temperatures.
The severity of Friday’s storms will depend on how conditions develop as the cold front approaches. Residents should check the latest National Weather Service forecasts for any changes to the timing or intensity of the weather.
The weekend may bring a distinctly wintry feel to parts of the region, even as the calendar remains in October.
