A Winter Weather Advisory is in effect until 9 pm for Kossuth, Humboldt, Pocahontas, Webster, Wright, Franklin, Hamilton, Hardin, and Grundy county. This is were pockets of 3″+ are possible this afternoon with low visibility due to strong wind and two different bands of snow.
Spotty snow showers will continue to move from west to east throughout the afternoon with the first band. Some areas along and south of I-80 could see some light rain to start the event, but temperatures will quickly cool and cause the light rain to change over to all snow. The secondary band will move from north to south throughout the evening tonight.
For those along and south of I-80, the second band of snow will begin after sunset, but for those in northern Iowa, the second band may begin to already move through just before the sun sets around 5 PM. Snowfall will continue to fall throughout the overnight and the wind is expected to be stronger as well. This may result in low visibility, so use caution if you plan on traveling across the state tonight.
Most of the state will see less than 2″ of snow, but areas north and east of Des Moines will see some pockets of 3″ of snow or more.
Snow looks to end before sunrise on Saturday in southern Iowa. Clouds will decrease throughout the day, but temperatures will stay in the 30s. Warmer weather will arrive overnight Saturday into Sunday resulting in rising overnight temps. That will give central Iowa the extra boost to reach the middle 40s in the afternoon.
