Higher elevations in the Northeast, such as the Adirondacks and Green Mountains, could see up to a foot of snow, while valleys may experience rain or a mix of rain and wet snow. Coastal areas, including Long Island and southwestern Connecticut, face minor flooding risks during high tides on Thursday and Friday. In the Deep South, temperatures may drop below freezing, potentially damaging plants and outdoor pipes. Commuters in mountain regions should prepare for slippery roads, while coastal residents should monitor flood advisories.
