The second phase is then expected from Sunday late morning into Sunday afternoon as warm air causes a transition to rain over a majority of southern Wisconsin. Thunderstorms may occur during this time. The last phase will then run from late Sunday afternoon through Monday as cold air then wraps back into the area and heavy banded snow moves in. Snowfall totals from 5 to 9 inches will result. A light glaze of ice may also occur, especially over central and east central Wisconsin. Wind gusts up to 45 mph will cause blowing snow and visibility restrictions. Hazardous travel is expected during both headline time frames. * WHAT...Heavy mixed precipitation possible. Total snow accumulations between 4 and 7 inches and ice accumulations around one tenth of an inch possible. Winds could gust as high as 45 mph. * WHERE...Portions of south central and southeast Wisconsin. * WHEN...From Sunday afternoon through Monday evening. * IMPACTS...Visibilities may drop below 1/4 mile due to falling and blowing snow. The strong winds and weight of snow on tree limbs may down power lines and could cause sporadic power outages. Travel could be very difficult. The hazardous conditions could impact the Monday morning and evening commutes. Gusty winds could bring down tree branches.

Stratocumulus clouds are similar to altocumulus clouds in their
fluffy appearance, but have a slightly darker shade due to their additional mass.
A good way to distinguish the two cloud types is to hold your hand out and measure
the size of an individual cloud; if it is the size of your thumb it is generally
an altocumulus cloud, if it is the size of your hand it is generally a
stratocumulus cloud.
It is uncommon for stratocumulus clouds to produce precipitation, but if they do
it is usually a light rain or snow.

Next Topic: Altocumulus Clouds
A wall cloud forms underneath the base of a cumulonimbus cloud,
and can be a hotbed for deadly tornadoes.
Wall clouds are formed by air flowing into the cumulonimbus clouds, which can
result in the wall cloud descending from the base of the cumulonimbus cloud, or
rising fractus clouds which join to the base of the storm cloud as the wall cloud
takes shape.
Wall clouds can be very large, and in the Northern Hemisphere they generally
form at the southern edge of cumulonimbus clouds.
