A storm that brought the chilliest air of the season so far, along with the lowest snow levels thus far this autumn for California, Nevada and Arizona will send snow to the mountains of Colorado and part of Wyoming into Friday.

This time the snow will stay from Denver, Cheyenne, Wyo., and Rapid City, S.D. The storm looks to be a tad warmer over the Rockies and High Plains, compared to last week's monster.

A foot of snow can fall on elevations above 7,000 feet in Colorado with enough snow, gusty winds and low visibility to make for dangerous travel through some of the passes. Wind gusts can reach between 40 and 60 mph, causing whiteouts.

Wind gusts up to 61 mph have been reported in Lamarie County, Wyo. In Colorado, a gust of 82 mph was recorded by Mesonet outside of Rocky Flats, and 84 mph outside of the town Marshall in Boulder County.

Power companies in Boulder County have reported between 11,000 and 12,000 customers without power from wind damage. A utility company in Jefferson County reported 1,500 without power.

Slippery travel is likely over the high ground along I-80 in Colorado and in Wyoming. However, I-80, I-25 and I-90 will be passable in this storm. Last week's storm closed long stretches of highways in Wyoming and western South Dakota.

Snow fell over the high ground in northern Arizona and the Wasatch Range in Utah Thursday morning, where a few inches to half a foot was forecast. A similar amount of snow fell Wednesday night in the Sierra Nevada and in the mountains of southern California.

Adverse Weather Watches and Warnings

This storm will bring windswept rain to the Black Hills area of South Dakota to western North Dakota. Flooding is possible in areas that had heavy snowfall from the prior storm.

Severe thunderstorms are a concern from around the Oklahoma Panhandle northward to western and central South Dakota, before cooler air sweeps in later Thursday night.

South of the storm track and its snow and rain, gusty winds will kick up dust into Friday especially in New Mexico, western Texas, the Oklahoma Panhandle and southeastern Colorado. The winds can be enough to cause handling problems for high-profile vehicles and cause sudden low visibility for all driving interests.

"Most furious storm in 20 years .... Snow rollers were seen in Battery Park when natural snowballs, formed when a strong gusty wind blows over a moist snow surface, were pushed along by the wind until they grew to a 24-inch diameter. At this point, they became too heavy and were left to dot Battery Park like so many boulders in a New England hayfield". (New York Post)
