This Date in Weather History

1921 - New England was in the midst of a four day icestorm, their worst of record. Ice was more than three inches thick in many places following the storm, and property damage was in the millions of dollars. Northern New England received heavy snow with more than two feet reported in some areas. Overnight freezing rains continued through the day at Worcester MA while the wind increased to a gale. Streets become impassable even on foot, and whole towns were plunged into darkness without communication. The storm caused 20 million dollars damage to power lines, telephone lines and trees.
