Weather Alert in Wisconsin
Winter Weather Advisory issued March 13 at 12:34AM CDT until March 13 at 1:00PM CDT by NWS La Crosse WI
AREAS AFFECTED: Clark
DESCRIPTION: ...TWO MAJOR WINTER STORMS OVERNIGHT AND THIS MORNING AND FROM SATURDAY NIGHT INTO MONDAY MORNING... .The first winter storm will move through northern Wisconsin from overnight tonight into this morning. It will bring 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 this morning, unsheltered areas will see blowing and drifting snow leading to hazardous driving conditions. Light snow and blowing snow are expected to linger through this morning and then decrease this afternoon. A 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 of 1 to 6 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, until 1 PM CDT this afternoon. 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. The hazardous conditions could impact the Friday morning and evening commutes. Gusty winds could bring down tree branches.

Next Topic: Evaporation
Drizzle is precipitation in the form of water droplets which are
smaller than raindrops.
Drizzle is characterized by fine, gently falling droplets and typically does not
impact human habitation in a negative way. The exception to this is freezing drizzle,
a condition where drizzle freezes immediately upon reaching earth's surface.
Freezing drizzle is still less dangerous than freezing rain, but can
potentially result in hazardous road conditions.

Next Topic: Fractus Clouds
Fog is technically a type of stratus cloud, which lies along the
ground and obscures visibility.
It is usually created when humidity in the air condenses into tiny water droplets.
Because of this, some places are more prone to foggy weather, such as regions
close to a body of water.
Fog is similar to mist; both are the appearance of water droplets suspended in
the air, but fog is the term applied to the condition when visibility is less than 1 km.
