Massachusetts residents are waking up to a deceptive bit of spring warmth as temperatures climb toward a record-challenging high of 66°F today. While the morning sun offers a brief “summer tease,” the atmosphere is shifting rapidly, with heavy clouds and a moisture-laden system positioned to swamp the region by the evening commute.
According to the National Weather Service in Norton, conditions will deteriorate sharply after 8 p.m. tonight. A potent combination of rain and patchy fog is expected to settle over the Boston metro area, reducing visibility on major arteries like I-90 and I-95. Forecasters are tracking a 90% chance of precipitation tonight, with new rainfall amounts between a quarter and a half of an inch possible before daybreak.
Drivers should prepare for slick pavement and ponding during the Friday morning rush. As the cold front passes, Friday’s high will struggle to reach 48°F—a nearly 20-degree drop from today’s warmth. This temperature swing introduces the risk of flash freezing on elevated surfaces and bridges as the mercury bottom out at 28°F on Friday night.
The weekend brings a biting chill to the Bay State. Saturday will remain crisp and breezy with a high of only 38°F, feeling much colder under northwest winds. While Sunday offers a slight rebound to 49°F with mostly sunny skies, residents should keep the heavy coats ready as overnight lows dip into the 20s. Looking ahead to early next week, another warm-up is on the horizon, but for now, the focus remains on the rain and fog moving in tonight.
