Boston woke up on Saturday, March 28, to a classic late-season fake-out: cloudy skies, a brisk north wind and temperatures stuck in the upper 20s. The good news is that the gray start gives way to plenty of sun this afternoon, a calmer breeze and a slow climb to a high near 37°F. The weekend stays dry, but a serious warmup late Sunday will flip the switch to a much milder, more unsettled setup as we head into next week.

Saturday Afternoon and Tonight

By this afternoon, expect mostly sunny skies with north winds around 8 to 12 mph and an afternoon high near 37°F. It will still feel cool, but the wind will gradually ease as the day wears on. Tonight turns partly cloudy with a low near 29°F as winds swing around to the west.

Out on the water, coastal areas dealt with a brief Small Craft Advisory early Saturday morning. That has settled down, and conditions should be relatively calm along the shore through Sunday.

Mild Air Muscles In Next Week

Temperatures start climbing on Monday, March 30, with highs near 59°F and breezy southwest winds that will finally make it feel like spring is at least trying. By Tuesday, March 31, highs push into the lower 60s.

Showers enter the picture Tuesday, with a chance of rain that becomes more likely on Wednesday, April 1. Wednesday looks like the big swing day, with highs potentially reaching the lower 70s and gusty southwest winds expected.

A front trailing that midweek system will nudge temperatures back toward more typical early April levels on Thursday, April 2. As the week wraps up, there is a chance that rain could mix with snow in some spots. According to the National Weather Service Boston/Norton, you should plan on periodic showers and breezy to windy conditions from Tuesday into Wednesday.

Heads-Up for Commuters and Boaters

The wet and windy stretch from Tuesday night into Wednesday could slow commutes and lead to scattered delays, so riders should keep an eye on service notices and budget extra travel time on March 31 and April 1.

Boaters and small-craft operators can expect building seas and stronger gusts in the middle of the week. It may be a better bet to exercise caution or postpone plans on more exposed waters during that period. Check MBTA service alerts and the latest marine updates before you head out.

Quick plan: enjoy the dry, milder feel on Monday, then have a jacket and an umbrella ready for the Tuesday and Wednesday commute. We will pass along any advisory changes before the midweek system arrives.
