Winter weather approaching NW Iowa will once again bring a threat of snow and ice accumulations along with gusty winds.  The National Weather Service has issued several advisories for the tri-state area, the most local include a Winter Weather Advisory for Lyon, Sioux, and Cherokee Counties in Iowa as well as Moody, Minnehaha, and Lincoln Counties in SD.  The advisory states mixed precipitation is expected this afternoon with a light glaze of ice this afternoon into the evening hours – higher ice accumulations tonight of up to a quarter inch with gusty winds up to 40mph. 


A Winter Storm Watch is in effect for Osceola, Dickinson, O’Brien, Clay, and Lyon Counties in Iowa, and all of SW Minnesota.  The watch area could see heavy mixed precipitation which include snow totals up to 3”, and ice accumulations up to three-tenths of an inch with winds gusting to 45mph.


Conditions in both advised areas could cause power outages and widespread tree damage.  Travel could become nearly impossible with patchy blowing snow reducing visibility to near zero.  These conditions could impact evening and morning commutes.


The Winter Weather Advisory is in effect until noon Tuesday, the Winter Storm Watch will remain in effect until late Wednesday night.  Conditions can change quickly, so can the advisories.  Stay alert to changing and updating conditions by keeping your radio tuned to KSOU.
