Weather/Hazards Highlights... Another day of lake effect snow is likely across the Great Lakes Thursday, with potentially heavy amounts piling up downwind of Lake Ontario after a snowy short range period too. Meanwhile, some light to moderate rain is forecast across the Southeast Thursday, while the low aloft could help produce some precipitation across southern California. Then precipitation is forecast to spread across parts of the Southwest, the southern/central Rockies, and across much of the southeastern U.S. into Friday. With the cold air in place, ice and snow are likely across much of the southern tier in likely a notable winter storm. The precipitation, including snow and ice, is forecast to spread east into the Carolinas and Mid-Atlantic on Saturday, lasting until Sunday and potentially spreading north into the Northeast. Model guidance has converged on the potential for an impactful storm, but it will take additional time to refine the details of precipitation amounts and type, so continue to monitor forecasts. Elsewhere, precipitation could increase across the Pacific Northwest and northern Rockies this weekend as shortwaves move through. -NWS .
