Planes are still taking off and landing at Portland International Airport even as the metro area enters its second day of winter conditions. Twenty-nine flights have been cancelled and 60 delayed so far Friday, with some of them having been pre-emptively cancelled overnight, Port of Portland spokesperson Allison Ferre said in an email.

Update: Storm Tracker 2 Meteorologist Rhonda Shelby says a back edge to the first band of precipitation is just about to move through the metro area.1

The National Weather Service NEXRAD radar in Portland that tracks rain, snow and sleet across northwest Oregon went out for about five hours Thursday morning but was back on by about 10:40 a.m., officials said.
