This Date in Weather History

1987 - A major winter storm hit the Great Lakes Region, intensifying explosively as it crossed northern Illinois. High winds and heavy snow created blizzard conditions in southeastern Wisconsin. Winds gusted to 73 mph, and snowfall totals ranged up to 17 inches at LaFarge. The barometric pressure at Chicago IL dropped three quarters of an inch in six hours to 28.96 inches, a record low reading for December. Up to a foot of snow blanketed northern Illinois, and winds in the Chicago area gusted to 75 mph. O'Hare Airport in Chicago was closed for several hours, for only the fourth time in twenty years. High winds derailed train cars at Avon IN. Light winds and partly sunny skies were reported near the center of the storm, a feature typical of tropical storms.

About Wailuku, HI

Wailuku is a census-designated place (CDP) in and county seat of Maui Island, Maui County, Hawaii, United States. The population was 17,697 at the 2020 census. Wailuku is located just west of Kahului, at the mouth of the ʻĪao Valley. In the early 20th century, Wailuku was the main tourist destination on Maui, though it has since been eclipsed with the rise of the resort towns such as Kihei. Historic sites in the town include Kaʻahumanu Church (named after Queen Kaʻahumanu, wife of Kamehameha I), which dates to 1876; the Wailuku Civic Center Historic District; the site of the Chee Kung Tong Society Building; and the Bailey House, a 19th-century former seminary and home that houses a history museum and the Maui Historical Society. There are two ancient temples near Wailuku, called heiau — the Halekiʻi Heiau and the Pihanakalani Heiau. Both date back hundreds of years and were used for religious purposes by the native Hawaiians. Wailuku is served by Kahului Airport.
