MINNEAPOLIS (AP) - A wallop of winter weather continues to make travel difficult on some Minnesota highways and byways, but air traffic seems to be running more smoothly at Minneapolis-St. Paul International Airport.

About 20 departures and arrivals out of about 800 have been canceled Tuesday morning, compared to about 150 at this time Monday. Airport spokesman Patrick Hogan says two of three runways that are usually operational are open Tuesday.

A winter weather advisory is set to expire as an additional one to two inches of snowfall comes to an end in eastern Minnesota.
