Winter Storm Details

Monday, February 19, 2018

A complicated winter storm system will bring snow, blowing snow and even some freezing drizzle to the region today, tonight and tomorrow. A Winter Weather Advisory is in effect for much of eastern South Dakota, southwestern Minnesota and northwestern Iowa this evening into tomorrow. A Winter Storm Warning is in effect today and tonight for much of central and western South Dakota.

SNow will come in a couple of rounds. Round one has already developed across much of central and northern South Dakota this morning. Snow will continue to develop and move east throughout the day today. Wind gusts to 25 mph or higher will create areas of blowing snow at times. A second, heavier round of snow is likely tonight into tomorrow morning. In addition to the snow, parts of northwestern Iowa and southern Minnesota could get areas of freezing drizzle today and again tomorrow.

This is a large system that will affect everyone a little differently. Here’s a breakdown detailing the impact on specific parts of our region:
