•Friday morning: Areas Coast Range eastward, with the greatest risk being in Clark County, the Willapa Hills, the Cowlitz River Valley, and the Columbia River Gorge. The risk of a significant event decreases south of Portland, with only a very slight chance of a significant event near Eugene.
•Friday morning: Snow and ice may impact the Friday morning commute, even within the main metro areas. Worst case scenario for the metro areas has about 2 inches of snow and/or a tenth of an inch of ice. Greater snow and ice accumulations are possible but not likely in the Gorge.
•Friday morning: Greatest risk prior to 8am, though there is some uncertainty. Much warmer air should cause a rapid thaw for most areas around mid-morning, with the Gorge being last to thaw around midday or early Friday afternoon.
•Friday morning: Low. Timing will be everything, as precipitation will need to start before temperatures rise above freezing for snow and ice issues to occur. Details will become clearer as today progresses.
