Wednesday is off to a mild, partly sunny start in Boston, with Logan Airport reporting about 68°F and a light west breeze. Temperatures are expected to climb into the upper 70s to near 80°F this afternoon, and the added low-level humidity inland could make it feel a bit sticky. Most neighborhoods stay dry, although a few isolated showers or a brief thunderstorm may pop up later today along the South Shore and across southeast Massachusetts.
Afternoon Heat and Isolated Storms
As the warmth combines with increasing moisture from roughly 2 to 7 p.m., a couple of quick-hitting showers or a short-lived thunderstorm could flare up, mainly from the South Shore toward the approaches to Cape Cod. West winds will run around 8 to 12 mph, with somewhat higher gusts along the coast, so expect it to feel breezier at waterfront parks and piers. According to the National Weather Service Boston, the thunderstorm threat is limited and focused along south-facing shoreline areas.
Cooler, Showery Late Week
A cold front slides through Wednesday night and knocks daytime highs on Thursday back into the mid-60s, with scattered light showers possible and nighttime lows dipping into the upper 50s. Rain chances increase again Friday into Friday night, and steadier, more widespread rain is likely late Friday night into Saturday, with lows in the low 50s during the wetter stretch.

Weekend Outlook and Boaters
Saturday looks like the chilliest and wettest day of the period, with afternoon highs near 60°F, rain showers likely, and north winds gusting in the mid-to-high teens (around 14 to 18 mph). Coastal waters may turn rougher, with seas building up to about 5 feet and a moderate chance for Small Craft Advisory level winds over the outer harbor. Sunday should shape up as the drier and more comfortable day of the weekend, with most locations drying out and highs rebounding into the low 60s.
How To Plan
It is worth having a backup plan for outdoor events later this week and, if possible, shifting bigger gatherings to Sunday for better odds of dry weather. Keep an eye on updated forecasts before heading out, and boaters should pay close attention to marine forecasts if they are planning trips from Friday night into Saturday.
