Boston woke up Saturday under a stubborn marine cloud deck, with skies stuck on mostly cloudy and temperatures hovering in the mid-50s. Light onshore winds will keep the immediate coast cooler than inland neighborhoods and hold afternoon highs near 61°F.
Rain, Timing And Marine Advisories
Showers are expected to roll in late Saturday night, after 3 a.m. Sunday, May 24 in some spots, then turn widespread through Sunday, keeping the day cool and damp. The National Weather Service now expects roughly 0.5 to 1 inch of rain for most of Greater Boston, with 1 to 2 inches possible along the south coast, and is flagging periods of steadier rain and patchy fog. Small craft advisories are posted for many southern and outer waters Sunday into early Monday as southeast winds pick up and seas build to 6 to 10 feet. Gusts could reach 25 to 35 mph offshore and 20 to 30 mph on land at times, according to the National Weather Service.
Memorial Day Outlook
Memorial Day, Monday, May 25, will start on the damp side with a chance of morning showers but should dry out through the afternoon with highs near 65°F, which offers a better window for ceremonies and cookouts. For more background and our earlier weekend preview, see our weekend breakdown.
Pack a compact umbrella for Sunday and line up backup plans for outdoor events, and secure loose patio furniture if you live near the waterfront. Check the National Weather Service marine forecast before heading out to the harbor for the latest advisories and any updates.
