DESCRIPTION: ...WINTER WEATHER ADVISORY FOR ACCUMULATING SNOW AND GUSTY WINDS ACROSS WEST CENTRAL MINNESOTA... .Updated Advisory to include Goodhue County. Rain has already begun to transition to snow across a significant portion of southern Minnesota, including along and south of the Minnesota River and into the western outskirts of the Twin Cities metro. As temperatures continue to fall, we expect rain to transition to snow, with a heavier narrow band of higher accumulations expected to move across the region this afternoon into the evening. Alongside the wet snow, strong winds are expected with gusts as high as 45-50mph, and although the wet snow should not blow around once it is on the ground, it will result in reduced visibility as it falls. Slick travel is expected due to slushy snow and gusty winds. * WHAT...Snow expected. Total snow accumulations of 1 to 2 inches. Winds gusting as high as 40 mph. * WHERE...Goodhue County. * WHEN...Until 9 PM CST this evening. * IMPACTS...Plan on slippery road conditions.

Weather Topic: What is Graupel?
Home - Education - Precipitation - Graupel
Next Topic: Hail
Graupel is a form of precipitation that is created by atmospheric conditions
which cause supercooled water droplets to contact snow crystals and freeze to
their surface.
Sometimes known as soft hail or snow pellets, graupel is delicate and easily
destroyed by touch. Whereas hail usually falls during severe weather, graupel
doesn't require such conditions to form, and can form in mild precipitation
similar to situations which produce snowfall.

A hole punch cloud is an unusual occurrence when a disk-shaped
hole appears in a cirrostratus, cirrocumulus, or altocumulus cloud.
When part of the cloud forms ice crystals, water droplets in the surrounding area
of the cloud evaporate. The effect of this process produces a large elliptical
gap in the cloud. The hole punch cloud formation is rare, but it is not specific
to any geographic area.
Other names which have been used to describe this phenomena include fallstreak hole,
skypunch, and cloud hole.
