Effective: Mon December 1, 2025, 6:20 AM

Special Weather Statement issued December 1 at 6:58AM EST by NWS Boston/Norton MA

Effective: Mon December 1, 2025, 6:58 AM
Expires: Mon December 1, 2025, 9:30 AM

Patchy black ice is possible this morning, as temperatures have fallen below freezing. Moisture remaining from yesterday's rain is refreezing, creating slick conditions on untreated surfaces like sidewalks, driveways, and bridges. Conditions will improve later this morning as temperatures rise above freezing. Motorist and pedestrians should use caution. Reduce speed, allow extra time, and be prepared for areas of slippery travel.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
