Full Notification

...MAJOR WINTER STORM SATURDAY NIGHT INTO MONDAY MORNING... .A prolonged, high-impact winter storm affects the region Saturday night 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 are warranting of 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 until further details can be ascertained. 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...For the Winter Weather Advisory, snow and blowing snow. Winds gusting as high as 40 mph. For the Winter Storm Warning, heavy snow expected. Total snow accumulations between 12 and 18 inches with localized amounts approaching 24 inches. Winds gusting up to 45 mph may result in blizzard conditions later Sunday into Monday morning.

* WHERE...Clark County.

* WHEN...For the Winter Weather Advisory, until 1 PM CDT this afternoon. For the Winter Storm Warning, from 7 PM Saturday to 1 PM CDT Monday.

* IMPACTS...Travel could be very difficult to impossible. Widespread blowing snow could significantly reduce visibility. The hazardous conditions could impact the Friday evening and Monday morning commutes. Gusty winds could bring down tree branches.

* AFFECTED AREAS: CLARK
