• 2 Tornados hit Springfield, IL

What is a tornado?
Tornado is a a rotating column of air ranging in
width from a few yards to more than a mile and
whirling at destructively high speeds, usually
accompanied by a funnel-shaped downward extension
of a cumulonimbus cloud. Tornadoes occur most
often in association with thunderstorms. This
happens during the spring and summer in the
mid-latitudes of both the Northern and Southern
Hemispheres. These whirling atmospheric vortices
can generate the strongest winds known on Earth
wind speeds in the range of 500 km (300 miles)
per hour have been estimated.

• When winds of this magnitude strike a populated
  area, they can cause fantastic destruction and
  great loss of life, mainly through injuries from
  flying debris and collapsing structures. Most
  tornadoes, however, are comparatively weak events
  that occur in sparsely populated areas and cause
  minor damage.

Most people would not be surprised to find that
Oklahoma has one of the most dangerous cities in
the US using this data, but look at the list of
other cities toping the list. Below are the top 9
Cities for Long Track F3 to F5 Tornadoes in the
United States from 1880 to 2003. The frequency of
long track F3 to F5 tornadoes per 1,000 square
miles is given for each city as a value. The
higher the value the more dangerous.
Tornado 1 This tornado was on the ground for
about 60 miles before it moved into Springfield.
The tornado crossed Interstate 72 near mile
marker 92, around 820 PM. It entered the city of
Springfield near Cockrell Lane and Constitution
Drive, tracking to the east-northeast around 50
mph. The tornado was about 300 yards wide, and
produced F2 damage to several businesses from
Constitution Drive, through Parkway Pointe, to
Veterans Parkway and Lindbergh Blvd. The tornado
widened to about 0.4 mile wide as it continued to
track east-northeast south of Wabash Avenue,
between Veterans Parkway and Chatham Road. The
tornado widened further, to just over 1/2 mile
wide from Westchester Blvd to the village of
Jerome. The damage was rated as F2 along Wabash
Avenue, between Chatham Road and MacArthur
Blvd. The tornado then weakened slightly,
producing F1 damage, as it turned to the
northeast, nearly parallel with the Norfolk
Southern Railroad tracks. The damage path
remained nearly 1/2 mile wide. The width of the
tornado decreased to about 1/4 mile wide as it
strengthened again, and turned to the
north-northeast near Iles Park and in the
vicinity of Oak and Myrtle Streets, between 6th
and 9th Streets. The damage was rated as F2 in
these locations, with roofs blown off of homes
and businesses, and garages severely damaged.
This tornado dissipated just north of 9th Street
and South Grand Avenue. This first tornado was on
the ground in the city of Springfield for nearly
5.5 miles, for approximately 6 minutes between
820 and 826 PM. The estimated wind speed with
this F2 tornado in the city was around 120 mph.
28
Tornado 2 A second tornado developed as the
first tornado was dissipating, around 825 PM.
This tornado touched down about 1/4 mile north of
the Bunn Park golf course, and tracked to the
northeast. The strongest damage was bounded by
15th Street, Cornell Avenue, South Grand Avenue,
and Pope Avenue. Several homes had roofs torn
off, with extensive damage to power poles and
lines, along with numerous downed trees. The
tornado continued to track northeast across Old
Rochester Road, Singer Avenue, and Cook Street
from White City Blvd. to a block east of Dirksen
Parkway. The tornado crossed I-55 at the Clear
Lake Avenue interchange, and overturned a semi
truck. This tornado dissipated near Old Route 36,
about 3/4 mile southwest of the Village of Clear
Lake. This second tornado was on the ground for
nearly 4 miles, for approximately 5 minutes
between 825 and 830 PM. The estimated wind
speeds with this tornado were also around 120
mph.

• Mayor Tim Davlin said he expected "every square
  inch of Springfield" will have suffered some
  effect from the storms. "It's just unreal,"
  Davlin said early Monday from the city's
  Emergency Operations Center.
