DESCRIPTION: ...DANGEROUS WINTER STORM LIKELY TO BRING EXTREME SNOW ACCUMULATIONS AND GUSTY WINDS... ...TRAVEL MAY BECOME IMPOSSIBLE LATE SATURDAY NIGHT AND SUNDAY... .A major winter storm will move across the Upper Midwest late Saturday into Sunday. Model guidance continues to illustrate a remarkable precipitation footprint across the region which will yield heavy snow accumulations on the order of 1 to 2 feet. Totals across portions of western and central Wisconsin could exceed 2 feet. The combination of heavy snow and gusty winds will reduce visibility and create periods of blizzard conditions on Sunday across western and southern Minnesota. Travel is expected to become very difficult or impossible late Saturday night and Sunday. In addition, the amount of water in the snowpack will make it wet and very heavy, leading to the potential for infrastructure damage and a health hazard for those shoveling. * WHAT...Heavy snow and blowing snow possible. Total snow accumulations between 18 and 28 inches possible. Winds could gust as high as 40 mph. * WHERE...Barron, Polk, Chippewa, Dunn, Eau Claire, Pepin, Pierce, and St. Croix Counties. * WHEN...From Saturday evening through Monday morning. * IMPACTS...Travel could be very difficult to impossible. Widespread blowing snow could significantly reduce visibility. The hazardous conditions could impact the Monday morning commute.

Next Topic: Hole Punch Clouds
Hail is a form of precipitation which is recognized by large solid balls or
clumps of ice. Hail is created by thunderstorm clouds with strong updrafts of wind.
As the hailstones remain in the updraft, ice is deposited onto them until their
weight becomes heavy enough for them to fall to the earth's surface.
Hail storms can cause significant damage to crops, aircrafts, and man-made structures,
despite the fact that the duration is usually less than ten minutes.

A mammatus cloud is a cloud with a unique feature which resembles
a web of pouches hanging along the base of the cloud.
In the United States, mammatus clouds tend to form in the warmer months, commonly
in the Midwest and eastern regions.
While they usually form at the bottom of a cumulonimbis cloud, they can also form
under altostratus, altocumulus, stratocumulus, and cirrus clouds. Mammatus clouds
warn that severe weather is close.
