National Weather Service– A winter storm watch is in effect from Thursday evening through Saturday Morning. Heavy snowfall is possible. Mixed precipitation is also possible at times especially south of Interstate 80. Total snow accumulations of 4 to 8 inches and a glaze of ice accumulation are possible.
Winds could gust as high as 45 mph later Friday and Friday night, producing significant drifting and blowing snow. Also, rapidly falling temperatures may produce a flash freeze by Friday evening and add to the slick conditions.
This storm watch covers portions of north central, northwest and west central Illinois and east central, northeast and southeast Iowa. Moderate to heavy snowfall is expected to impact much of the area late Thursday night into Friday, with highest accumulations expected over central and southern Iowa.
Hazardous travel is likely, especially during the morning and evening commutes on Friday. Bitter cold temperatures will accompany this storm, adding an extra layer of risk to travel. Travel could be very difficult and dangerous. Areas of blowing snow could significantly reduce visibility. The hazardous conditions could impact the Friday morning and evening commute. Gusty winds could bring down tree branches.
