Showers precede spring warm-up

The last weekend of spring semester will get off to a rainy start. A frontal system will pass through the area today and tomorrow, bringing the possibility of rain showers, and even the occasional thunderstorm. Today, in advance of the system, onshore winds will combine with cloud cover to keep temperatures in check. However, a warm front will pass through the area overnight, leading to considerably warmer temperatures during the day on Saturday.

After the system passes through, above-normal temperatures will arise in its wake. Bright sunshine and a strong offshore wind will combine to bring temperatures into the middle 70s (°F) on Sunday, and temperatures could even flirt with the 80°F mark in spots on Monday. In contrast, the normal high temperature for Boston on May 12 is 65°F.
