The path drawn at its surveyed width of 100 yards (0.06 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

An EF1 tornado touched down in Stow, MA near Maple street and continued ENE over Bose Avenue causing significant tree damage. The tornado lifted somewhere near Harvest Drive and touched down again about 1.25 miles ENE just west of Packard road and continued across Carriage lane before lifting again. This tornado caused significant tree damage with several hard and softwood trees uprooted or snapped at the trunk.

The wider storm

A cold front moved through Southern New England in the afternoon bringing a round of severe storms which caused a wide swath of wind damage through MA with some in western CT. Some severe hail occurred in northern MA and a single storm dropped 5 tornadoes in central MA which led to widespread tree damage along but limited damage to structures.

Began near Hudson (42.4298, -71.5510).
