The only infallible rule about tornado paths is "they go where they
d*mn well please". E.g. the 'wisdom' that tornadoes won't cross a
river valley. See Xenia, Ohio, 1974 for how accurate *that* wisdom
is.

Since 1855 there have been 89 'significant' tornadoes in the Chicago
area. One in 1876 ripped apart buildings in downtown Chicago, a large
multiple-vortex tornado was seen moving out over Lake Michigan. 2
fatalities, 35 injured.

In 1896, one went through Park Ridge, Edison Park, and Norwood Park.

In 1912, one touched down in (now Skokie), and carried through Wilmette.

1920, a biggie, starting around Romeoville, going through Maywood/Bellwood,
and all the way to Wilmette. a 53 mile(!) ground track.

1963, wholly inside the city -- from 91st & Western to 68th and the
lake. $7 million in damages -- 1 killed, 115 injured.

1967, Palos Hills to Oak lawn, to Chicago's South side; over $50
million in damages, _33_ killed, 500 injured.

Several 'smaller' tornadoes have hit near Evanston since the 1950s, and,
in 1961 and 1967, tornadoes hit just south of the U of C on the south side.

As for (modern) big cities being immune, on March 28, 2000, a twister
went through downtown Fort Worth TX, killing 2, and causing $400
million in damages. Oklahoma City, Miami, Nashville, Salt Lake City,
Cincinnati, Birmingham, and Washington D.C. have also been hit in
recent years.

for a picture of a tornado among the skyscrapers.

See: http://www.usatoday.com/weather/tornado/wtcities.htm for stuff on
big-city hits.
