Boston woke up Thursday, May 28 to mostly clear skies at Logan Airport and a comfortable 61°F, but a cool onshore breeze is keeping the immediate coastline a few degrees lower. Through the day, expect partly sunny skies and a high near 67°F, with scattered showers developing after about 11 a.m.
Afternoon Showers Tap The Brakes On Warmup
That mix of sun and clouds comes with roughly a 40% chance of light rain showers this afternoon, although new rainfall totals should stay under a tenth of an inch. North winds around 9 mph will keep things feeling brisk for late May. Tonight, temperatures dip to about 53°F with a few spotty showers still hanging around. Friday, May 29 stays on the cool and mostly dry side, with highs near 65°F and only a slight chance of a few late-day showers.
Saturday Turns Blustery With Gale Watch Offshore
The real shake-up arrives Saturday, May 30, as a stronger low-pressure system moves through and drags in rain showers and gusty northerly winds. Highs struggle into only the low 50s. The National Weather Service has issued a Gale Watch for much of the coastal and outer waters for Saturday, calling for north winds of 25 to 35 kt with gusts up to 40 kt and seas of 5 to 8 feet. On land, gusts of 30 to 40 mph are possible, with a few stronger bursts in exposed spots. Mariners should plan on staying in port, and anyone onshore would be wise to secure loose outdoor items and prepare for possible ferry interruptions. For marine details, see the National Weather Service Boston/Norton.
Plan Ahead
If your plans involved a Saturday on the harbor, it is time to start eyeing Sunday, May 31 instead. Sunday looks drier and more seasonable, with highs near 65°F. In the meantime, secure patio furniture and umbrellas, build in extra commute time on Saturday, and keep an eye out for any ferry or marina service notices.
