Ahead of the cold outbreak this weekend, a weather system will pass across the state and bring light to moderate snow during the day Friday.
Snow will begin to enter northwest Iowa after 7am Friday and will continue to spread to the southeast. Snow will then begin falling across central and eastern Iowa around 10am Friday. The snow will then begin to tapper off first across northwest Iowa around 4 to 5pm, and will eventually end across the state by 9pm.
Regarding snowfall totals, there will be a narrow corridor extending from northwest Iowa to east central and southeast Iowa where 1 to 3 inches will be possible. A few spots may receive up to 4 inches within the band of snow. The snowfall forecast above is using a snowfall ratio of 10:1, but snowfall ratios will likely be higher. At this time, models have also been increasing the amount of moisture with this system, so it is possible that snowfall totals may be even higher than what is shown above, so continue to monitor our page for any updates regarding snowfall totals.
With the passage of this system an arctic high will move into the region and bring bitterly cold air into Iowa. Look for an update on the dangerous cold wind chills expected this weekend later on this afternoon.
