Weather Alert in Iowa
Winter Storm Watch issued March 14 at 6:11AM CDT until March 16 at 1:00PM CDT by NWS La Crosse WI
AREAS AFFECTED: Floyd; Chickasaw; Fayette; Clayton; Grant
DESCRIPTION: ...MAJOR WINTER STORM TONIGHT INTO MONDAY MORNING... .A prolonged, high-impact winter storm affects the region tonight through Monday morning. Highest snow totals in excess of 12 to 18 inches are favored north of Interstate 90 with some locales north of Highway 10 approaching 24 inches. Along Interstate 90, a wintry mix of snow, freezing rain, and sleet makes it difficult to pin down exact snow and ice amounts, but impacts do warrant a Winter Storm Warning. Across northeast Iowa and southwest Wisconsin, snow does not look to arrive until Sunday afternoon, so the Winter Storm Watch is maintained for now. Increasing winds Sunday afternoon and night should result in whiteout conditions for exposed locales and an upgrade to a Blizzard Warning is likely once the exact threat area is determined. Regardless of exact snow amounts, expect major travel impacts regionwide with some roads possibly impassable, especially in wind-prone areas. * WHAT...Heavy snow possible. Total snow accumulations between 3 and 6 inches possible. Winds could gust as high as 55 mph and may result in blizzard conditions later Sunday into Monday morning. * WHERE...In Iowa, Floyd, Chickasaw, Clayton, and Fayette Counties. In Wisconsin, Grant County. * WHEN...From Sunday afternoon through Monday afternoon. * IMPACTS...Travel could be very difficult. Widespread blowing snow could significantly reduce visibility. The hazardous conditions could impact the Monday morning commute. Gusty winds could bring down tree branches.

Next Topic: Cumulus Clouds
The final form taken by a growing cumulus cloud is the
cumulonimbus cloud, which is very tall and dense.
The tower of a cumulonimbus cloud can soar 23 km into the atmosphere, although
most commonly they stop growing at an altitude of 6 km.
Even small cumulonimbus clouds appear very large in comparison to other cloud types.
They can signal the approach of stormy weather, such as thunderstorms or blizzards.

Weather Topic: What is Drizzle?

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.
