(Bloomberg) -- Washington D.C. could get another four inches (10 centimeters) of snow by late Sunday from a storm that’s already caused hundreds of flight cancellations as it cut a wide swath across the U.S. from St. Louis to the Mid-Atlantic.

Totals could reach 10 inches before the sun returns Monday and temperatures rise into the 40s Fahrenheit by Tuesday, said Rob St. Pierre, a meteorologist with Hometown Forecast Services in Nashua, New Hampshire.

“They will get off-and-on snow today and then it will clear out late tonight,” said St. Pierre, who provides forecasts for Bloomberg Radio. “There will be sunshine Monday, Tuesday and Wednesday.”

As of 8 a.m. in Washington, 461 flights were canceled around the U.S., with the majority of those from the three Washington-area airports -- Reagan National, Dulles International and Baltimore/Washington International -- according to FlightAware, a Houston-based airline tracking service.

Earlier St. Louis got 10.2 inches with some parts of Missouri getting more than a foot, according to the National Weather Service.
