Over 1,500 flights were canceled Tuesday in the U.S. due to bad, very cold weather. “We expect to operate on a reduced schedule throughout the week,” United spokesperson Robert Einhorn told to media. “Wintry precipitation could delay flights today from Boston (BOS) to Atlanta (ATL), as well as in Chicago (MDW, ORD),” The FAA’s daily air traffic report said Tuesday morning. Many carriers have waived change fees for affected airports. Dangerously cold conditions are forecast this week. Wind chills values will fall into the 40s, 50s, even 60s below zero in some places.
By Wednesday and Thursday, morning lows may reach the minus 20s to perhaps minus 30 in the Twin Cities, with minus teens and minus 20s in Des Moines, Iowa, Chicago and Milwaukee. Thursday will be the coldest day along the Northeast Interstate 95 corridor. Chicago and Rockford, Illinois may be within a few degrees of their all-time records of minus 27 degrees, set Jan. 20, 1985 and Jan. 10, 1982, respectively. In the Dakotas, Minnesota, Iowa and St. Louis, the all-time records still stand from more than 100 years ago. Grand Forks Airport in North Dakota reported a wind chill of 61 degrees below zero on Tuesday.
