Its location at the intersection of Interstates 57 and 24, and Illinois Route 13, a primary east-west four-lane expressway, gives it access to the major communities of Murphysboro, Carbondale, Carterville, Herrin, Marion and Harrisburg. Although the Williamson County population is only 66,357, it is located in the heart of the Metro Lakeland area of Jackson-Williamson Counties where 120,000 citizens of Illinois make their home. Carbondale (14 miles west), Herrin and Marion are the key urban areas in Metro Lakeland, with a combined population of over 65,000. Over 235,000 people live within 35 miles (56 km).

History

Williamson County was formed out of Franklin County on February 28, 1839, and was named for Williamson County, Tennessee.[3]

Williamson County is often referred to as "Bloody Williamson" due to several outbreaks of violence that have few parallels in American history.[4] These include the Bloody Vendetta (1876), the Carterville Massacre (1899), Coal Strike (1906), The Herrin Massacre (1922), the Klan War (1924–1926), and the Birger/Shelton Gang War, 1926. The Illinois National Guard was deployed repeatedly during the 1920s to separate the warring parties and attempt to keep order.

As with the entire United States, severe weather in Williamson County is not uncommon. The northwest section of the county was obliterated by the Tri-State Tornado of 1925. The county was also struck by 2 tornadoes on May 29, 1982 killing 10 people in the Marion, Illinois tornado outbreak. On May 8, 2009, the cities of Carterville, Herrin, and Marion were severely damaged by the May 2009 Southern Midwest derecho.

Williamson County lies on the border between humid continental climate (Köppen climate classification Dfa) and humid subtropical climate (Köppen climate classification Cfa), with neither large mountains nor large bodies of water to moderate its temperature. It is subject to both cold Arctic air and hot, humid tropical air from the Gulf of Mexico and, along with the rest of the midwestern United States, is home to some of the largest temperature extremes in the world. The region has four distinct seasons. Spring is the wettest season and produces erratic severe weather ranging from tornadoes to winter storms. Summers are hot and humid with only occasional and brief respite, and the humidity often makes the heat index rise to temperatures feeling well above 100 °F (38 °C). Fall is mild with lower humidity and can produce intermittent bouts of heavy rainfall with the first snow flurries usually forming in late November. Winters are cold with periodic snow and temperatures often below freezing, however thaws are usually frequent. Winter storm systems, such as Alberta clippers and Panhandle hooks, can bring days of heavy freezing rain, ice pellets, and snowfall.

The normal high temperature in July is 90 °F (32 °C), and the normal low temperature in January is 19 °F (−6 °C), although this varies from year to year. Both 100 °F (37.8 °C) and 0 °F (−17.8 °C) temperatures can be seen on an average 2 or 3 days per year. In recent years, average temperatures have ranged from a low of 19 °F (−7 °C) in January to a high of 88 °F (31 °C) in July, although a record low of −25 °F (−32 °C) was recorded in January 1977 and a record high of 113 °F (45 °C) was recorded in August 1977. Average monthly precipitation ranged from 3.06 inches (78 mm) in October to 4.93 inches (125 mm) in May.[16]

Williamson County experiences thunderstorms about 50 days a year on average. Thunderstorms contribute over half of the annual precipitation. Especially in the spring, these storms can often be severe, with high winds, large hail and tornadoes.

Some late autumns feature the warm weather known as Indian summer; some years see roses in bloom as late as early December.
