Green Bay, WI – A sharp change in Wisconsin's weather is expected later this week, bringing rain, powerful wind gusts and the likelihood of a hard freeze Saturday morning, October 17. Residents across northeastern Wisconsin, including the Fox Valley and communities farther north and west, should prepare for a significant cooldown heading into the weekend.
According to the National Weather Service in Green Bay, the changing weather pattern will begin with relatively mild conditions Tuesday, October 13, before temperatures gradually fall through the remainder of the week.
Tuesday will feature temperatures reaching between 57 and 72 degrees, with areas of early morning fog possible. Wednesday, October 14, will remain relatively comfortable, with highs ranging from 54 to 65 degrees.
Conditions are expected to change Thursday, October 15, as rain becomes likely across the region. Temperatures will reach approximately 54 to 60 degrees.
By Friday, October 16, cooler and windier conditions will arrive. The National Weather Service forecasts highs between 47 and 56 degrees, with wind gusts exceeding 35 mph possible.
The biggest concern arrives Saturday morning, October 17, when a hard freeze is considered likely from the Fox Valley northward and westward.
A hard freeze can damage or kill sensitive plants and remaining garden vegetation. Residents with outdoor plants, gardens or exposed seasonal vegetation should consider protective measures before temperatures fall.
The forecast graphic indicates Saturday afternoon temperatures may recover into the 53 to 60 degree range, despite the morning freeze threat.
Drivers should also prepare for wet roads Thursday and potentially challenging travel conditions during Friday's stronger winds, particularly on exposed highways.
Fortunately, the colder weather is not expected to last long. Forecasters indicate above normal temperatures should return early next week.
Residents are encouraged to monitor updated National Weather Service forecasts as the weekend approaches.
