CHEYENNE, Wyo. (AP) - A large spring snowstorm delivering heavy snow, high winds and rain is causing travel problems from Wyoming to Chicago.
In Wyoming, some big stretches of Interstates 25 and 80 have reopened, but snow and blowing conditions were still making driving dangerous along the interstates and smaller highways.
Freezing rain, snow and strong winds, were hitting Kansas and South Dakota, where numerous local elections were postponed. Some schools in Minnesota dismissed students early.
Around 500 flights have been cancelled in Denver and deicing has delayed departures. Flights bound for Chicago's O'Hare International Airport are being delayed an average of nearly four hours because of dense fog.
