Boston started Saturday under low clouds and low-to-mid 40s, but skies are set to brighten through midday. By this afternoon, expect mostly sunny conditions and a high near 48°F. It will not be a totally calm spring preview though, as a growing northwest breeze will make it feel cooler and a bit blustery at times. If you are heading out, think light layers and make sure anything loose outside is tied down.

Afternoon Winds Pick Up

Northwest winds are forecast around 9 to 13 mph with gusts up to about 24 mph into the evening. The strongest gusts should arrive between late afternoon and sundown, easing after dark. Coastal and exposed areas will feel the wind most, and mariners should note that Small Craft Advisories remain in effect on some outer waters this morning. Forecasters add that an unsettled pattern returns Sunday into Monday, bringing rain that could briefly mix with wet snow in spots, according to the National Weather Service Boston/Norton.

Sunday Into Monday: Rain Likely, Wet Snow Possible

Rain is likely on Sunday, with most neighborhoods topping out in the upper 40s. A steadier band of rain may arrive late Sunday into Monday, bringing a few tenths to around a half inch of liquid. Colder air moves in Sunday night, and areas north of the Mass Pike and in higher terrain could see the rain flip to wet snow, leading to minor, slushy accumulations in a few locations Monday morning. Timing and exact amounts remain uncertain, and small shifts in the front could change who sees snow instead of plain rain.

What This Means For Your Plans

If you are planning to be outside this weekend, treat Saturday as your better bet for errands and outdoor time, but bring a windproof layer. For Sunday night, have a solid rain plan. If you commute Monday morning, allow extra time and watch for localized slick spots where wet snow or sleet might briefly mix in.

Bottom line: bright and breezy today, then wetter and chillier to kick off next week. Keep an eye on local updates if you have to travel Monday morning.
