A record December total of 34 inches was received. (David Ludlum) 1903: Wilbur and Orville Wright made four brief flights at Kitty Hawk, North Carolina with their first powered aircraft on this day. After having success with their 5-foot biplane kite, the brothers realized the weather conditions in Dayton were not ideal for their flying experiments. They wrote the Weather Bureau in Washington, D.C. requesting a list of suitable places on the east coast where winds were constant. Below is the response the Wright Brothers received from Joseph Dosher, who staffed the Weather Bureau office, wrote in August of 1900 regarding the suitability of Kitty Hawk. 1924 - A severe icestorm struck central Illinois. It coated the ground with nearly two inches of glaze at Springfield. The storm caused 21 million dollars damage along with much hardship. Ice was on the trees until the 4th of January, and electricity was not restored until January 10th. (David Ludlum) 1924: From the Monthly Weather Review, "a severe glaze storm occurred in west-central Illinois on December 17 and 18, the area of great destruction embracing a territory about 75 miles in width and 170 miles in length. In the affected area, trees were badly damaged, wires broken, and thousands of electric poles went down. Electric services were paralyzed, and it required weeks to restore operation and months to permanently rebuild the lines. The street railway company and the Illinois Traction System resumed complete operation 17 days after the storm. Electric light service was completely restored January 10. The ice had practically disappeared from the trees and wires by January 4, but on January 20, there was still considerable ice on the ground. The Western Union Telegraph Co. lost 8,000 poles and the Illinois Bell Telephone Co. about 23,000. The total damage to wire service in Illinois probably equaled or exceeded $5,000,000." If the loss of business, the damage to trees and possible injury to winter grains, the storm may be considered one of the most disastrous of its kind in the history of Illinois." 1929 - An icestorm in western New York State resulted in much damage and hardship.
