The prospect of high winds and heavy snowfall has led the National Weather Service (NWS) office in Des Moines to extend and upgrade to a winter storm warning for the Perry area from 9 a.m. Friday until 6 p.m. Saturday.
Three to six inches of snow and up to one-tenth of an inch of ice are forecast, with winds gusting to 45 mph over central and south-central Iowa, according to the NWS.
Snow will start to fall Friday morning and might be heavy at times during the morning and afternoon hours before eventually transitioning into a period of light wintry mix or freezing rain.
A strong cold front will sweep through Saturday morning, bringing with it very strong winds, falling temperatures and possibly some additional light snowfall. Winds will switch from out of the south to the northwest, with gusts up to 50 mph during the morning hours
High winds will persist throughout the day Saturday, possibly leading to periods of near-blizzard conditions in parts of central and north-central Iowa.
The highest snowfall accumulations will reach six inches in north central Iowa, with lesser
amounts of three to four inches farther south, according to the NWS.
Travelers should plan on slippery road conditions, with patchy blowing snow significantly reducing visibility. These hazardous conditions could impact the morning and evening commute on Friday.
