GRAND RAPIDS — The forecast from FOX 17 Chief Meteorologist Kevin Craig: Unseasonably mild air will be with us overnight as low pressure continues to move to our northeast pulling a warm front north of the area. Temperatures will stay mild enough for just rain showers on Friday, but as colder air works in upon stiff north to northeast winds Friday night into Saturday morning, this rain will change to freezing rain and sleet. This icy mess of weather will continue through the day on Saturday, with dangerous travel likely and numerous power outages possible. WINTER STORM WATCHES have been posted for the entire area from Friday night through Sunday morning, so we're expecting a long duration event. We're also anticipating 2" to 4" of total precipitation, which is an unprecedented amount of moisture for this time of year. A significant icing event of .50" to 1" or more is possible for parts of West Michigan, coupled with sustained winds of 20 to 30 mph. We expect this will produce a crippling effect in the area with widespread power outages for long durations during this unusual high impact event. Please be safe.
