...Dangerous Winter Storm To Impact The Region Tonight through Friday Night...Dangerous Travel Expected... .A dangerous winter storm will impact the area tonight through Friday night. This storm will contain strong winds, heavy snow, rain, a wintry mix, and thunderstorms. Due to considerable snow accumulations and strong wind, there will be significant impacts to travel for most of the area. Blizzard Warnings continue for portions of southeast Minnesota and northeast Iowa while Winter Storm Warnings and Advisories continue for the rest of the area. As of 930 PM, precipitation has moved northward, impacting areas mainly south of Interstate 94. While mostly rain, precipitation has changed over to snow or a wintry mix across portions of northeast Iowa and southeast Minnesota. Snow, rain, or a wintry mix will continue to lift northeastward late this evening and overnight. Snow is beginning to cover roads for areas mainly west of the Mississippi River, so slick travel conditions can be expected. Snow accumulations through midnight will be 1 to 2 inches for these areas. Travel will then become dangerous overnight through Friday as snow becomes heavy coupled with strong northerly winds causing blowing and drifting of the snow. Snow accumulations from 1 to 4 inches are expected overnight, highest north of a Charles City Iowa, Winona Minnesota, and Black River Falls Wisconsin line. Some thundersnow will also occur, adding to snowfall rates and reduced visibilities. Light icing could also mainly south of I- 90. Plan on mostly snow continuing Friday through Friday night, although a mix with rain or freezing precipitation could occur near and south of Interstate 90 at times during the day Friday. An additional 4 to 12 inches of snow is expected Friday through Friday night with the highest amounts expected across southeast Minnesota into west central Wisconsin. Strong north winds with gusts 35 to 45 mph will cause significant blowing and drifting of the snow Friday and Friday night which will cause some whiteouts. This will be especially true in open and unsheltered areas. Expect any slush or standing water to freeze Friday night into Saturday morning. Prepare now for this dangerous winter storm, especially if you have travel plans. ...WINTER WEATHER ADVISORY REMAINS IN EFFECT UNTIL 6 AM CST SATURDAY...

* Mostly rain late this evening will transition to a wintry mix around midnight and then diminish around 6 AM Saturday.

* The heaviest snowfall rates will occur Friday evening, and the greatest amount of ice accumulation looks to occur Friday morning.

* Total snow accumulations of 3 to 7 inches and ice accumulations of 2/10 of an inch are expected.

* Winds gusting as high as 35 mph will cause patchy blowing and drifting snow, especially on ridge tops and in open areas. In addition, some reductions in visibility are expected.

* The ice and snow will result in difficult travel conditions, including during the morning and evening commutes on Friday.

A winter weather advisory means that periods of snow...sleet or freezing rain will cause travel difficulties. Be prepared for slippery roads and limited visibilities...and use caution while driving. The latest road conditions for the state you are calling from can be obtained by calling 5 1 1.
