MINNEAPOLIS - Another wintry blast has buried northeastern Minnesota under more than a foot and a-half of new snow, disrupted travel and closed schools.

The National Weather Service says 22 inches of snow has fallen in the Lake County community of Two Harbors, with 20 inches at Lake Nichols in St. Louis County. Duluth, Proctor and Cloquet are among the school districts canceling classes.

The heavy snow left more than 6,000 Minnesota Power customers without service early Friday. Utility crews made swift progress in restoring power.

The mounting snow is a record for Duluth in April. With nearly 42 inches of snow so far, it easily surpassed 31.6 inches set in 1950. Forecasters say lake-effect snow should continue to fall along Wisconsin's south shore, with a band of moderate snow in Carlton and northern Pine counties.
