It’s only been a little over a month into fall and the first winter storm of the season is already coming to the US.

A winter storm will hit parts of the Pacific Northwest, the northern Rockies and parts of the Northern Plains, with snow falling from the Cascades and the Sierra.

Parts of the country to experience cold air plunge

Temperatures will plunge into the Plains, eventually reaching eastern parts of the country next week, bringing cold air to the week of Halloween.

Cold air and moisture are expected to extend from Washington and Oregon all through Montana on Tuesday before a storm hits the Northwest on Tuesday evening. People who live in higher elevations can expect a greater probability of treacherous snow.

The northern Rockies are expected to experience snowfall beginning Tuesday, which will extend to northern Minnesota on Friday.

This weather event will be the first snow of the season for some parts of the US, with the amounts ranging from light to heavy. The Sierra, Wasatch, parts of South Dakota, and northern Minnesota, are forecast to receive lighter quantities of snow, according to The Weather Channel.

Meanwhile, the Cascades, Bitterroots and Tetons, as well as western North Dakota and much of Montana have the biggest chance of heavy snow, which could reach up to six inches or more. Some mountain passes in the Cascades, including Snoqualmie Pass, Stampede Pass, and Stevens Pass, are likely to see snow-covered, slippery roads and highly dangerous travel conditions with poor visibiity.

The winter storm could be followed by another stripe of snow that may develop by Friday night, with snowfall hitting areas further south, possibly bringing the first snow to Denver and Salt Lake City.
