...ON THIS DATE IN WEATHER HISTORY...

In 1987, severe thunderstorms invaded the northwest &
northern United States from Utah to North Dakota.  In
Teton County Wyoming, around 45 miles northeast of
Jackson, a huge F4 tornado cut across the Teton
Wilderness.  The tornado`s track was 24 miles long and
reportedly nearly one and a half miles wide.  It leveled
around 15,000 trees.  Occurring at an elevation of around
10,000 feet, it was the highest elevation of an F4
tornado on record.  Most of the trees that were leveled
were 80 to 100 foot tall mature Lodgepole Pines.  Parts
of North Dakota were raked by 12 tornadoes, baseball
sized hail, and destructive winds.  The high winds
toppled a pair of 80 foot radio towers near Blanchard.
In 1911, the low temperature plunged to 10 degrees in
Painter Wyoming.  This set the all time record low for
July in the continental United States.

In 1983, the world`s coldest temperature, a wonderful
128.5 degrees below zero, was measured at Vostok,
Antarctica.  This broke the previous world record of 127
degrees below zero that had been set on August 24th,
1960.
