Snow will begin to fall across the north-central Brooks Range this afternoon and spread east as a low-pressure system drops south into Alaska from the high Arctic. A Winter Storm Warning is in effect beginning midnight tonight through Tuesday morning for heavy snow totaling 4 to 8 inches in the eastern Brooks Range including the Dalton Highway.
A mix of rain and snow is expected along the immediate Arctic Coast where temperatures will hover near or just above freezing. Scattered showers are possible across the Interior late tonight into Monday as a low moves east through the Gulf of Alaska.
Further south, snow is likely across higher elevations of the Alaska Range Monday into Tuesday, including light accumulations around 1-inch on Denali Park Road passes. Most of the West Coast will remain clear of precipitation, through rain is likely across the Y-K Delta and lower Yukon south of Galena this afternoon into early Monday.
