Monday night: Clouds increase late at night.
In Seattle, where such snow is a rarity, residents cleared out grocery store shelves and left work early Friday afternoon as the storm arrived. A few flurries may decorate the area before sunrise, but the main wave of moisture will move in from Iowa into southern Minnesota toward sunrise and then into central Minnesota shortly after that. In addition, as the temperature rises past the freezing mark, an extended period of sleet and freezing rain could lead to a glaze of ice. The greatest impact from the storm will be north along Interstate 70 and the northern Maryland counties.
"Snow conditions are worsening minute to minute, so don't expect travel conditions to improve", the sheriff's office wrote. The National Weather Service office in Eureka reported accumulating snow at sea level.
Douglas and Burnett counties remain under a winter storm watch, as does Pine County in Minnesota. "I was born and raised here; we don't get these kinds of systems often".
Another bout of winter weather is headed for Toronto and the GTA this week. "Another 1-2" will fall during the evening before tapering off before midnight.
Because of how unprepared Seattle was for recent weather, some have jokingly labelled the recent storms as Seattle's "Snowpocalypse" or "Snowmageddon" on social media. Scattered rain showers for Tuesday afternoon that will transition to scattered snow showers Tuesday night. Total snowfall amounts of 25 to 35 cm are likely before the snow tapers off during the day Wednesday.
The city's extreme cold weather alerts are issued when the temperature is forecast to reach -15 degrees C or colder, or when the wind chill is forecast to reach -20 or colder. There will be a brief break before another system arrives.
