Boston’s weather flip-flops: From cold rains to possible storms

Cape Cod, Martha’s Vineyard, Nantucket, Boston, Northeast, USAMonday, May 4, 2026

A Stormy Start to the Week

This week in Boston kicked off with an unexpected deluge—rain lashed the city alongside blustery northwest winds. While Cape Cod and the nearby islands soaked up over an inch of rainfall from a storm spinning offshore, eastern Massachusetts was left under a blanket of gray skies and gusty conditions. Temperatures barely crept past the fifties, making it feel more like the onset of spring rather than its usual mid-season warmth.

A Sudden Warm-Up on the Horizon

But hold onto your hats—things are about to shift dramatically. A powerful jet stream adjustment paired with a high-pressure zone near Bermuda will funnel warmer air northward by Monday. The south coast and islands will bask in the sixties, while Boston inches closer to seventy degrees. By Tuesday, the mercury could soar into the upper seventies—or even reach eighty—perfect timing for outdoor plans.

Stormy Surprises Ahead

Yet the weather isn’t ready to settle. Tuesday night could bring a round of thunderstorms over northern New England, though the city may dodge the worst of them. Wednesday steps in with a cold front that might ignite more widespread storms, followed by lingering rain through Thursday. And just when you thought it was safe, temperatures could plummet back to the fifties by the weekend.

A Weather Whiplash of Seasons

The first full week of May is proving cooler than expected. Highs may struggle to reach the sixties over Mother’s Day weekend—well below the normal range for early May. It’s a classic case of weather whiplash: one day feels like summer, the next like spring never left. Buckle up—Boston’s meteorological rollercoaster isn’t slowing down.
