Boston, Mass. – Sunshine and calm conditions will dominate Saturday in Boston, but a quick shift Sunday could disrupt weekend plans. Temperatures will climb to 83°F Saturday before spiking to near 92°F Sunday, when strong afternoon thunderstorms may develop. Travelers should watch for slick roads and reduced visibility, especially along I-93 and I-90 during peak return traffic Sunday evening.

By Sunday, southwest winds will usher in unstable air, increasing storm potential after 2 p.m. Some cells could produce heavy rain and gusty winds, with a 50% chance of showers and storms lingering into Sunday night.
Residents should secure outdoor furniture, plan earlier outings, and avoid nonessential driving if storms materialize. Boaters should monitor marine warnings, as storms could rapidly intensify over Boston Harbor and Massachusetts Bay late Sunday.
Monday returns to mostly sunny skies and cooler highs in the low 70s, offering a brief reprieve before another warm-up midweek. Tuesday stays seasonable, but light winds and clear nights could bring patchy morning fog inland.
