11:30am Friday: As what's been the case with the past two snow events, a main cold low pressure system will sit off the Oregon coast and spin waves of energy through the region. All ingredients need to come together just right for snow to fall in Cottage Grove, so we may end up with nothing. Chances of snow in Cottage Grove? 50/50 that we'll see no snow, rain/snow mix, or a dusting to 1".
