Boston weather: A dry and seasonable start to May
Enjoy the nice weather while you’ve got it, because it’s probably not going to last.
Fresh off of a beautiful and sun-splashed weekend, temperatures will cool down behind a cold
front on Monday afternoon. A few showers and perhaps a rumble of thunder will accompany the front on Monday afternoon, ushering in a generally cooler but drier pattern for the rest of the week for Boston and most of New England.
After a miserable April, though, it finally felt like spring this weekend. Temperatures soared into the 70s on both Saturday and Sunday under sunny skies in Boston, kicking off May in a dramatically different way than April ended.
While it won’t be nearly as warm as that most of this week, skies should at least stay mainly dry. After one more milder day in the 60s on Monday, highs will mostly rise up into the mid-to-upper 50s from Tuesday through Friday. There will be a couple of shower chances, starting on Wednesday night. Thursday looks to be the most unsettled day of the week with clouds and showers, but even then, a few breaks of sunshine should break through the clouds, and it shouldn’t be a total washout.
By Friday, the sun should re-emerge before a potential weekend storm system. But what might be a bit more significant is what lies ahead for next weekend and into next week.
The long-range outlook for next week trends sharply colder, likely bringing back the April-like temperatures. It may get cold enough to where some frost and freeze concerns could be in play during the peak of the cold snap, which’ll likely peak next Monday and Tuesday.
You’ve been warned: any (socially distant) outdoors Mother’s Day plans may be difficult next weekend, and next week overall trends colder as well. You might want to start planning on frost and freeze concerns for next week for your quarantine garden, especially for colder areas away from the coast.
It’s far from unheard of to get these early-to-mid May cold snaps, but a stubborn trough of low pressure anchored over the eastern U.S. will continue to keep New England locked into a chilly spring. After a brief break this week, that’ll likely be the story once again for next week.
In the near term, get outside and take in the sun and relatively mild temperatures. If next week’s forecast even comes close to fruition, you probably won’t want to spend a ton of time outdoors.
