Snowstorm to dive all the way into south-central US

Courtney Spamer

Another winterlike storm will dive through the central United States into early next week, bringing with it snow, ice and a shot of Arctic cold.

A weak storm will first plow southward from Canada into the north-central U.S. this weekend. Snow arrived across Montana and North Dakota later on Saturday will spread into South Dakota on Sunday.

By Sunday afternoon, some light snow may arrive in northern Nebraska, northwestern Iowa and southwestern Minnesota, before it could reach the Chicago area by late Sunday night.

Through Sunday night, the highest snowfall amounts will be confined to the highest elevations of the northern Rockies, where about a foot of snow is possible.

"A more widespread swath of 3 to 6 inches of snow is likely from southern Canada through Montana and into northern Wyoming and far-western South Dakota," AccuWeather Meteorologist Brett Edwards said.

Farther south and east, less snowfall, on the order of 1 to 3 inches, is expected. Communities such as Des Moines, Iowa, and Cheyenne, Wyoming, will lie in this zone expected to receive lighter snowfall.

Motorists across parts of Interstates 94, 90, 80 and 25 are likely to endure delays throughout the weekend as the storm takes aim.

The storm will intensify as it evolves over the central Plains, and Gulf moisture will stream in early next week.

Enough Arctic air is expected to plunge in and cause snow to break out across parts of Kansas and Oklahoma, and rain may mix with and change to ice or snow as far south as northern Texas on Monday.

While snowfall in this region in the first half of November is not common, most locations average half of an inch to 1 inch of accumulating snow in the month of November.

On Monday, steady snow appears most likely from central Missouri on eastward through the Ohio Valley and Northeast.

However, a messy commute may be possible on Monday morning in the Chicago, Denver and St. Louis areas.

Generally, any snow accumulations from eastern Colorado to western Missouri are expected to be light, if accumulations occur at all. How quickly cold air catches up with the storm will determine whether accumulating snow can reach this region.

"Should the cold, dry air diving southward across the northern Plains move in fast enough, there might be little in the way of snow in Oklahoma or Kansas," said AccuWeather Senior Meteorologist Brett Anderson.

The cold may infiltrate on the northern side of the storm to allow freezing drizzle and icy spots to develop in northern Texas.

"A rush of cold air will sharply drop temperatures behind the system Sunday night and Monday. Any lingering wet spots may rapidly freeze up," Edwards added.

Icy conditions may make travel difficult on roads like Interstates 27, 35 and 40 and may impact flights arriving at or departing from major airport hubs like Oklahoma City.

The storm will also grow in size while it strengthens throughout the day on Monday, which will allow snow to stretch as far north and east as northern New England.

More significant snowfall totals, including enough to plow, could be possible in locations from Ohio to Maine.

Behind the storm, record-challenging cold is expected across the Plains.

Temperatures well below freezing are expected Monday night, from all the way from Great Falls, Montana, to Dallas, Texas, helping any snow or ice on ground to linger a little longer.
