The forecast for this week is decidedly wintry, but give it three weeks and spring will really be in bloom -- at least if today's cherry blossom prediction from the National Park Service is right.

The cherry blossoms should peak between March 26-30, according to the park service's James Perry. Peak bloom means that 70 percent of the buds are in bloom. That window is almost a week later than 2012's peak bloom, which came on March 20, but a week ahead of the average peak bloom date of April 4.

The National Cherry Blossom Festival runs from March 20 to April 14. Popular events include the the Blossom Kite Festival (March 30), the Cherry Blossom 10-Mile Run (April 7) and the Japanese street festival and National Cherry Blossom Festival Parade (April 13).
