(Portland, OR)  --  Thawing is in the forecast today for Metro Portland, but some areas will see the going remain dangerous.  Some areas of Portland are predicted to see icy conditions held over from the weekend's winter storm, and some school districts began issuing cancellation notices last night.  Meteorologists say ice and snow will likely continue today along the Columbia River, higher-elevation areas, and into Eastern Multnomah County.  Police are urging drivers to be careful along the freeway, as icy patches are expected to form.
