The first systematized and synchronous weather observations were taken at 24 stations across the U.S. at 7:35 am. These observations were transmitted via telegraph to Washington DC for plotting on a national weather map. The Army Signal Service was assigned the responsibility for taking these observations.

Radiosondes are weather instruments that measure temperature, humidity, and barometric pressure of the atmosphere. These radiosondes are carried into the sky using weather balloons filled with helium or hydrogen. When inflated, the balloon is about 4-5 feet in diameter and several feet high. However, as the balloon ascends, the decreased effects of barometric pressure cause the balloon to expand. It will usually pop at an elevation close to 100,000 feet off the ground. By this time, the balloon is about the size of a small house.
November 5, 2005
Late season severe weather caused extensive wind damage across central and southeast Illinois, late on the 5th to just after midnight on the 6th.

Significant damage also occurred west of Bloomington, near Stanford.

November 7, 2010
Areas near the Great Lakes frequently deal with lake-effect snow during the fall and winter. These snows are produced when cold air picks up moisture while traveling across the relatively warmer lake waters. The air then rises to form clouds and snow. Generally, these lake-effect snows are found along east or south shores of the Great Lakes, but a northeast wind will produce lake-effect snow in northeastern Illinois.
November 8, 1956
The average first freeze of the fall season normally occurs in Springfield on October 22nd. However, during the fall of 1956, the first freeze didn't occur until this date, November 8th. This set a record for the city's latest first freeze.

November 14, 2010
Ice crystals sometimes act as prisms in the sky. If the Sun is positioned right, they can bend light rays and reflect them back to the light source. This causes a display known as a "sun pillar". Sun pillars are most likely around sunrise or sunset. They appear as columns of bright light extending upward or downward from the Sun.
November 15, 1988
A pair of strong tornadoes affected the eastern St. Louis metropolitan area.

Damage in Madison County alone was $1 million.
November 15, 2005
A tornado touched down 7 miles southwest of Newton, in Jasper County. The tornado downed numerous trees and power lines. The majority of the structure damage impacted outbuildings, barns, and grain bins. 11 outbuildings were severely damaged or destroyed. Three homes sustained minor damage. One attached garage was destroyed, with the debris carried 150 yards downwind. The tornado lifted about 3.5 miles northeast of Newton.

November 21, 2010
Central Illinois averages about 20 days a year where dense fog reduces visibility to 1/4 mile or less. However, the foggiest areas of the country are in the far western U.S., in mountain valleys and along the coast, in the Appalachian Mountains of the eastern U.S., and in southwestern New England. These areas usually see at least 80 days a year with dense fog.
November 22, 2010
Lenticular clouds are lens shaped in appearance, and frequently form one above another. They may lead to an increase in UFO sightings, because they can resemble spacecraft. Although they may be visible in Illinois on occasion, they are most common in mountainous areas.
November 23, 1950
Peoria had its earliest sub-zero temperature on record, with a low temperature of 1 degree below zero. This stood as a November record until 1977. Ironically, the all-time November record high was recorded earlier that month.
November 24, 1950
The early season cold wave continued in central Illinois. High temperatures of 6 degrees in Springfield and 8 degrees in Peoria both established the coldest November high temperature on record. Record lows were also established at both sites, with temperatures below zero.
November 25, 1908

November 25, 1996
A winter storm brought a mixture of freezing rain, sleet, snow, and high winds to central Illinois. This was the result of a strong low pressure system moving northeast from the lower Mississippi Valley, combining with cold air pushing south out of the Northern Plains. Significant icing occurred, causing numerous accidents and power outages. Several injuries were reported.

November 28, 2010
Ice crystals in the sky can sometimes cause interesting displays of light. A halo is such a display. Halos are caused when light rays are bent by ice crystals, forming a ring around the sun or moon. Weather folklore says that halos can be used to forecast precipitation. This is sometimes true, because high clouds containing ice crystals are the first clouds to move into an area ahead of an approaching low pressure system.
November 29, 2001
An area of low pressure intensified as it moved over southeast Illinois, creating strong gradient winds up to 62 mph. These winds only lasted for about half an hour. The winds blew down numerous large trees and power lines in Lawrence and Crawford Counties. No injuries were reported.
