THE POLAR FRONT JET -- Decades of radiosonde data and more
recent computer models of atmospheric flows have confirmed that
the strength and location of what has become known as the Polar
Front jet stream in upper level motions are linked to the formation,
movement, and evolution of the Highs and Lows of the surface weather
maps. For more detail on some of these relationships, see the

HISTORICAL WEATHER EVENTS - 8 April
From the files of the Aviation Weather Center, Kansas City,
MO and Intellicast
- ...1918...A big spring snowstorm buried the Potomac Highlands
of West Virginia with 34 inches of snow at Wardensville, 30 inches
at Moorefield, and 29 inches at Romney. (Intellicast)
- ...1919...A tornado swarm in northern Texas resulted in the
deaths of 64 persons. (David Ludlum)
- ...1929...A record heat wave hit the East, with New York City
experiencing its earliest 85 degree reading. (Intellicast)
- ...1973...A severe storm brought high winds and heavy snow
to Iowa. Belle Plain received 20 inches of snow, and 19 inches
blanketed Dubuque, record totals for both locations for so late
in the season. Snow drifts up to sixteen feet high closed highways.
(David Ludlum)
- ...1987...A cold front crossing the Northern Plateau and the
Northern Rocky Mountain Region produced high winds in northeastern
Wyoming. Winds gusting to 69 mph at Sheridan, WY downed power
lines and caused some property damage. (The National Weather Summary)
(Storm Data)
- ...1988...Strong northerly winds ushered cold air into the
north central U.S. The strong winds, gusting to 60 mph at Rapid
City, SD and Williston, ND, reduced visibilities in blowing dust
over the Dakotas. (The National Weather Summary) (Storm Data)
- ...1989...Two dozen cities in the southwestern U.S. reported
new record high temperatures for the date. Phoenix, AZ equaled
their record for April of 104 degrees established just the previous
day. (The National Weather Summary)
- ...1990...Twenty-two cities reported record low temperatures
for the date as readings dipped into the 20s and 30s across much
of the eastern U.S. Freezing temperatures severely damaged peach
and apple orchards in West Virginia, where prolonged mild weather
since January had caused an early blooming of spring vegetation.
State and Federal agencies estimated a 50 percent loss in production
for peaches and "Delicious Red Apples". (The National
Weather Summary) (Storm Data)
- ...1996...The first of two late season heavy snowfalls in
only three days over the northeast dumped 12 inches of snow at
Slide Mountain, NY, 10.2 inches, at Ashburnham, MA, and 7 inches
at Falmouth, MA. The 6.1 inches at Binghamton, NY brought its
seasonal snowfall total to 131.8 inches -- its snowiest winter
ever. (Intellicast)
