From California to Ohio, a big chunk of the U.S. is getting a blast of wintry weather. Some areas are experiencing frigid temperatures. Some are seeing snow and ice. The conditions are making travel difficult, raising concerns about citrus crops and prompting the cancellation of fights, holiday festivities and football games. Even one outdoor ice rink in cold-accustomed South Dakota is shutting down.

State-by-state weather summaries:
A storm rolling in over the weekend will keep northern Arizona in the grips of freezing temperatures, bringing more snow and making travel a little tricky.
Phoenix residents could see a dusting of snow in the surrounding mountains. Several inches of snow could fall in the higher terrain.
The cold weather is normal for this time of year, but the duration of chilly temperatures that will dip below zero in some parts of northern Arizona is what makes the recent and upcoming days "on the cold end of normal," said David Blanchard, a meteorologist with the National Weather Service in Flagstaff.
Tucson street crews were busy Thursday preparing for the weather by coating about 70 bridge decks with magnesium chloride to keep ice from sticking to roadways.
The National Weather Service issued an ice storm warning for the Interstate 40 corridor and other areas in Arkansas, as a storm that's expected to cripple much of the state into the weekend brought sleet that left roadways slick with ice and slush.
Forecasters say significant ice accumulations were expected across central Arkansas late Thursday through Friday.
Temperatures in the citrus-rich San Joaquin Valley dropped to the low 20s overnight, but officials said it's too early to tell whether there was any crop damage.
To protect the $2 billion citrus crop, farmers are using a number of techniques, including pumping water into groves to warm the soil and using wind machines to circulate the warm air rising from the ground.
