Joe Lundberg, a senior meteorologist from AccuWeather, discussed the upcoming storm affecting the Greater Portland area. He predicted three to six inches of snow, with potential for up to eight inches in northeastern areas. The storm is expected to start in the afternoon and last through the night, with minimal accumulations after late tonight. Post-Christmas, another cold front with arctic air is anticipated, followed by a potential snow and ice event late Sunday. Temperatures are expected to remain below freezing, with some relief in January. Lundberg confirmed a white Christmas and ongoing cold weather for the next few weeks.
