A winter storm will bring a wintry mix of precipitation to Iowa late Thursday into early Saturday morning. The greatest threat for moderate and heavy snowfall is over north central and northwest Iowa. Strong north to northwesterly winds will lead to dangerous travel during periods of heavier snow and conditions will reach or exceed blizzard criteria.
Rain will transition to snow Thursday night into early Friday morning with winds increasing through the day on Friday. The precipitation and winds are expected to persist into early Saturday morning.
Snowfall accumulations in the blizzard warning will range from 9 to 13 inches. Wind will be from the north/northwest, sustained at 20 to 30-mph with gusts over 40-mph. Visibilities will be reduced to one halfmile or less during periods of heavier snow and wind.
Travel will become very dangerous to near impossible as blowing and drifting snow reduce visibility Friday into early Saturday morning.
Areas in the purple are in a winter weather advisory. Snowfall accumulations of 4 to 7 inches are expected in this area. Winds will be gusting up to 40-mph, which will reduce visibilities to one half mile or less during periods of heavier snow and wind.
