A low pressure system across Kansas will shift northeast across Iowa overnight, before exiting across southern Minnesota and Wisconsin on Friday. The result will be a mix of rain and snow over central South Dakota, transitioning to mainly rain this afternoon. As colder air works in from the northwest this evening, winds will increase and precipitation will turn to all snow. Expect moderate to heavy snow, with significant blowing snow and dramatically reduced visibilities overnight into Friday. Hazardous travel conditions are expected, especially across eastern South Dakota, and west central Minnesota overnight through much of the day Friday. Snow and blowing snow will slowly end west to east Friday afternoon.
A blizzard warning has been issued from midnight tonight to 6pm Friday. Blizzard conditions will develop around midnight and then diminish around 6pm Friday, as precipitation ends west to east. 5 to 10 inches of snow is expected in this warning area.
Winter storm warnings and winter weather advisories have also been issued fro Nebraska, South Dakota, Wyoming, and Minnesota.
