Weather - Janesville Sesquicentennial
 
[Three photographs; caption reads: The ravages of weather have raised havoc with city residents and businesses over the years. In the photo at left, heavy rains flooded parts of Janesville in 1942, including Five Points intersection. The view is looking west, with West Court Street veering off the top right of the picture. In the above photo, shopping carts were tossed upside down and light poles were downed in the Creston Park parking lot by a violent wind in the early 1970s.

Mother Nature has shown her fury
Like many Midwestern communities, Janesville has been buried in snow, battered by wind, pelted
with hail, inundated with rain, broiled in heat, shaken by tremors, stiffened with cold, and basked in sunny pleasant weather.
Variety has been the mainstay of weather for Janesville residents over the past 150 years. It's led to
a common belief that if you don't like the weather in Janesville just wait a day or two and it will change.
One major exception occurred in 1936 when a record low of minus 29 degrees was established on
Jan. 23 - and then held on through one of the longest cold spells ever to settle upon the area. Temperatures dropped below zero on 11 of the last 12 days of January and on 19 of the 28 days in February.
Periods of steamy days also have been recorded. In July of 1955, it climbed above 90 degrees for
21 days in succession. But, when you talk about local heat waves you have to go back to the summer of 1936 when Janesville's all-time high temperature of 110.5 degrees was set on July 14.
The historical heat wave started innocently enough on June 26 when the mercury only hit 89
degrees. The following day it zoomed to 99 degrees and the next it was 94. A cool spell dropped temperatures into the 70s and 80s until July 7 when the temperature soared to 103.
High temperatures the next nine days were: 107, 106, 104, 108, 104, 106, 110.5, 110, 100. After
a cool 97 degree day, the temperature jumped over the 100 mark again three times by the end of July. The hot spell finally broke in August, when it only topped the 100-degree mark twice, including 105 degrees on Aug. 19.
While everyday weather is probably the most talked-about subject in day-to-day conversations, it
is the extreme storms that highlight weather history.
Janesville has had its share of old-fashioned thunder and lightning storms, but it has escaped some
real natural disasters that have skirted the city's perimeter on more than one occasion.
Folklore indicates that Janesville has been spared the fury of tornadoes and cyclones because the
city is located on the bend of Rock River. That theory has been discounted as mere superstition by state climatologists.
Records in a book, "Transactions of the Wisconsin Academy of Science, Arts and Letters," dated
1965, indicate Janesville was hit once by a tornado in the period between 1883 to 1960. That one instance occurred May 28, 1955.
Since then a second tornado inched into the city limits when it destroyed part of the Janesville
Country Club on Jan. 24, 1967. It was initially described as a big wind storm, but later confirmed as a rare January tornado.
Destructive tornadoes have skirted the city several times. The most famous is the "11-11-11,"
which occurred on Nov. 11, 1911.
On that day, Janesville reported a high temperature of 72 degrees at 2 p.m. and by midnight it was
down to zero. A man in Monroe froze to death that night.
That tornado touched down near Brodhead and moved eastward toward Rock County. Nine
persons lost their lives, barns were ground into kindling, the Willowdale School was destroyed and Hanover was heavily damaged. Storm damage was a quarter-mile wide as it approached Janesville and then veered northward where it slipped between the villages of Milton and Milton Junction without damaging either.
April 11, 1965, Palm Sunday, is still imprinted in the minds of many local residents as well as the
balance of the country. On that fateful day a total of 37 twisters were reported across the nation killing a total of 214 people.

The nearest one blasted the city of Monroe and caused considerable damage to northern Rock
County. The city escaped damage.
Monroe was struck again by another tornado on June 9, 1979, and again it moved in the direction
of Janesville only to turn northward causing damage to the Evansville and Edgerton areas.
A storm described as a cyclone struck on Sept. 21, 1931. It touched down west of Orfordville
near Highway 92 and roared toward Janesville and swung just north of the city. Near Milton Junction, the storm split into two paths, one going toward Indianford and the second moved along Highway 59 east to Lima Center and on into Jefferson County. The storm caused thousands of dollars in damage.
Two of the worst wind storms occurred June 20, 1934, when an estimated $100,000 in damage
was reported in this area, and on June 16, 1973, when strong wind and heavy rain caused extensive damage. The city estimated its cleanup cost for that storm at $16,000 and the county paid out more than $30,000.
Hail in other parts of the country is often described as pea- or golf ball-sized. In Janesville on Sept.
20, 1934, "hail as big as hen's eggs" fell on the city."
Janesville averages 31 inches of snow each winter. The snowiest winter of record came in 1978-
79 when a whopping 69 inches was recorded breaking the previous record of 57 inches set in 1951. Since snowfall statistics for around the turn of the century are not available this stands as the modern-day standard.
March of 1976 is recalled as the "ice age" in Southern Wisconsin. Freezing rain and damaging high
winds caused $7.7 million in damages and it was deemed the worst disaster in the state since the 1973 flooding that caused $24 million in damage.
Ice-coated power lines and trees resulted in the loss of electricity for half a million people, some
of whom were without power for up to 10 days. Area farmers were forced to rely on portable generators to complete milking chores.
Earthquakes are rare in Wisconsin, but Janesville residents have been shaken by at least four. The
first occurred Oct. 31, 1895. On the morning of Jan. 2, 1912, Janesville was shaken by another, but no damage was reported except for some broken windows and dishes.
An earth tremor shook the city again on Nov. 9, 1968. No damage was reported but people
reported downtown buildings swayed and one woman reported her husband nearly drowned from the waves in his bathtub.
The last one came Sept. 15, 1972, at 12:23 a.m. Residents reported beds rocked and dishes
rattled for about 30 seconds. The quake, centered near Peoria, registered between 4.5 and 4.7 on the Richter Scale.
The first climatological station in Janesville was supervised by the Smithsonian Institution.
Temperature observations were taken from January 1853 to July 1862, and precipitation observations from January 1854 to Dec. 1858. A second series of observations was taken from January 1891 to November 1895.
A rain gauge was installed at the Wisconsin Power & Light Co. substation on March 22, 1941.
Temperature readings were added at that location on Aug. 19, 1944. The weather readings are still recorded there.
