Weather Alert in Wisconsin
Winter Weather Advisory issued March 12 at 2:30PM CDT until March 13 at 1:00PM CDT by NWS La Crosse WI
AREAS AFFECTED: Clark
DESCRIPTION: ...TWO MAJOR WINTER STORMS TONIGHT INTO FRI MORNING AND SAT NIGHT INTO MON MORNING... .The first winter moves through northern Wisconsin tonight into Friday morning bringing snow to areas along and north of US Highway 10 in central Wisconsin with expected amounts rising rapidly north of Wisconsin Highway 29. With wind gusts ramping up overnight to 45 to 50 mph by Friday morning, unsheltered areas will see blowing and drifting snow leading to hazardous driving conditions. Light snow and blowing snow are expected to linger through the morning before winds begin decreasing Friday afternoon. The second winter storm could approach historic levels as a large band of 12 to 18 inches of snow falls across the region with localized amounts up to 24 inches. The main uncertainty in the forecast is exactly where this band sets up with the highest confidence currently from southeast Minnesota to between I-90 and Highway 29 in Wisconsin. There will be a relatively sharp gradient in snow amounts on the southern side of the snow band over northeast Iowa and southwest Wisconsin. In addition to the heavy snow, winds increase Sunday afternoon into Monday morning, with gusts of 35 to 50 mph possible west of the Mississippi River. These winds could lead to widespread blowing and drifting of snow and blizzard conditions, especially west of the Mississippi River. Regardless of exact snow amounts, expect widespread major travel impacts regionwide with some roads possibly becoming impassable. * WHAT...For the Winter Weather Advisory, snow expected. Total snow accumulations up to 3 inches. Winds gusting as high as 55 mph. For the Winter Storm Watch, heavy snow possible. Highest total snow accumulations between 12 and 18 inches with localized amounts approaching 24 inches possible. Lesser amounts of 6 to 12 inches of snow possible outside of this band. Winds could gust as high as 40 mph. * WHERE...Clark County. * WHEN...For the Winter Weather Advisory, from 7 PM this evening to 1 PM CDT Friday. For the Winter Storm Watch, from Saturday evening through Monday afternoon. * IMPACTS...Travel could be very difficult to impossible. Areas of blowing snow could significantly reduce visibility.

Stratus clouds are similar to altostratus clouds, but form at a
lower altitude and are identified by their fog-like appearance, lacking the
distinguishing features of most clouds.
Stratus clouds are wider than most clouds, and their base has a smooth, uniform
look which is lighter in color than a nimbostratus cloud.
The presence of a stratus cloud indicates the possibility of minor precipitation,
such as drizzle, but heavier precipitation does not typically arrive in the form
of a stratus cloud.

Similar to cirrocumulus clouds, altocumulus clouds are
characterized by cloud patches. They are distinguished by larger cloudlets
than cirrocumulus clouds but are still smaller than stratocumulus clouds.
Altocumulus clouds most commonly form in middle altitudes (between 2 and 5 km)
and may resemble, at times, the shape of a flying saucer.
These uncommon formations, called altocumulus lenticularis, are created by uplift
in the atmosphere and are most often seen in close proximity to mountains.
