Significant Thanksgiving Storm

A significant storm system will move into Iowa tonight and affect the area through Friday morning. As colder air moves southeast across the region Thanksgiving day, a transition zone of freezing rain is expected to occur along with some sleet and light snow. Though some uncertainties remain regarding ice accumulations, western and southwest portions of Iowa are at risk of receiving between 0.15″ and 0.2″ of ice during the event with lighter amounts to a 0.1″ over a large portion of central Iowa.

Rain will begin to change to freezing rain by early Thanksgiving morning and last into the evening hours. Lingering light freezing drizzle is possible overnight. Light freezing rain will occur elsewhere in central Iowa through early Friday morning.

Iowa Snowfall Forecast

Snowfall accumulations will generally remain two inches or less, with the heaviest snowfall accumulations across northwest Iowa.

Iowa Ice Accumulations

Ice accumulations will be up to 0.15″ to 0.2″ with the greatest ice accumulations across southwest Iowa.

North winds will increase to 15 to 25mph Thursday night across  the area. Though roads are expected to become icy and travel impacted during the day and night, another impact may be from ice accumulating on colder exposed surfaces of buildings, trees, and wires. With winds increasing during the night there will be a possibility of tree damage and isolated power outages.
