Heat wave of 1995 derecho series

A tremendously hot and humid air mass over the Great Plains contributed to the development of four powerful derechos.

This derecho raced through eight states in 24 hours: Montana, North Dakota, Minnesota, Wisconsin, Michigan, Ohio and parts of Pennsylvania and West Virginia as well as one Canadian province, Ontario.

This was termed a 'right turn' derecho because its initial eastward progression moved sharply to a south-southeast direction, having developed from a band of thunderstorms in Montana.

The derecho wreaked havoc in southwestern Ontario, hundreds of trees fell and damage was caused to buildings.

After crossing the open waters of Lake Huron/Georgian Bay, the storm raced southeastward into central southern Ontario.

Across the lake from the trailer park, straightline winds caused extensive damage in the cottage community of Long Point.

Further east, near Peterborough, an F2 tornado hit Bridgenorth damaging or destroying 20 homes and a marina with winds estimated upward of 200 km/h (120 mp/h).

Many thousands of trees were blown down across the province severing power lines, blocking roadways, and damaging homes.

Fifty people were left homeless after the derecho blew the roof off an apartment building in Holyoke, Massachusetts.

Three people were injured in Deerfield, Massachusetts when a hot air balloon got caught into the winds of the derecho gust front and blew into a tree.
