A Blizzard Warning remains in effect for portions of west-central and southwest Minnesota starting this morning and continuing through the afternoon.
A Winter Weather Advisory has been issued east of the Blizzard Warning for blowing snow and possible near-blizzard conditions at times, as well as the potential for flash freezing roadways and surfaces as temperatures, plummet this afternoon behind an Arctic front.
Wind ChillWarnings remain in effect for west central through southwestern Minnesota and have been extended farther east into central and south-central Minnesota.
Confidence remains high based on upstream observations that blizzard conditions will develop this morning and afternoon across portions of west-central and southwest Minnesota, mainly west of a Morris to Redwood Falls to St. James line. East of the blizzard warning, winds will be lighter and visibilities are not expected to drop to blizzard criteria, but areas of blowing snow and periods of near-blizzard conditions remain possible during a few hours of light snow later this morning and afternoon.
Plummeting temperatures this afternoon and evening may lead to flash freezing of this light snow on roadways and surfaces, with impacts to the evening commute expected. In addition to the blizzard conditions, temperatures will drop off sharply behind the Arctic front. Wind chill values will drop to 25 to 30 degrees below zero by this afternoon in west-central Minnesota, with wind chills of 35 to 40 degrees below zero likely by the evening. These dangerous wind chills will continue into mid-morning Thursday. In eastern Minnesota into western Wisconsin, wind chills will drop to between 25 and 35 degrees below zero late Wednesday night through Thursday morning.
