Boston is getting a brief weather gift Saturday: a mix of clouds and sun, crisp air and an afternoon high in the mid-60s. The calm stretch is on a timer, though, with rain expected Sunday and showers possibly lingering into Monday morning. The National Weather Service’s Logan observations and forecast give the latest conditions and outlook.
Saturday Brings Crisp Air And Sunshine
Skies are forecast to turn sunny through the rest of the day, with a high in the mid-60s and northwest/north-northwest winds of 6 to 10 knots. The National Weather Service’s current Logan forecast and observations provide the latest readings.
Saturday night turns partly cloudy, with a low near 48 degrees and calm winds. It should be a comfortable evening for outdoor plans, though anyone staying out late will want a jacket. The National Weather Service forecast for Logan calls for partly cloudy skies and a low around 48.
Rain Arrives Sunday Afternoon
Sunday will be mostly cloudy with a high near 63 degrees, and showers could begin arriving during the afternoon before becoming more likely Sunday night. The overnight low is expected to be around 55, with rainfall totals generally between one-half and three-quarters of an inch possible.
The rain forecast reflects a broader moisture surge moving into Southern New England; forecasters expect about half an inch in northern areas and around an inch in southern areas through Monday midday, with some South Coast spots possibly nearing 1.5 inches. The National Weather Service’s Boston/Norton discussion says the expected short duration and totals do not point to a flooding concern, though the precise arrival and exit times remain uncertain.
Rain is likely to exit by Monday morning, with drying by the afternoon, though lingering showers are possible, especially south of Boston.
The rain may also affect flight conditions at Logan. The NWS aviation outlook calls for ceilings to lower as rain arrives Sunday, with marginal or poor flying conditions possible Sunday night and locally on Columbus Day. That is a forecast of weather conditions for pilots—not a prediction of specific delays or cancellations.
More Showers Could Return Tuesday
A round of rain is possible around Tuesday or Tuesday night, with improving weather afterward. The National Weather Service’s Boston Logan forecast gives the latest outlook.
Dry weather is expected Wednesday into Thursday, with a quiet, seasonable stretch. No watches or warnings are currently posted for Boston or Massachusetts.
