2012 Growing Season and Frost and Freeze Update

The National Weather Service (NWS) uses a combination of Frost Advisories and Freeze Warnings to highlight conditions when frost or freezes are expected in the early fall that might impact sensitive vegetation. Typically the NWS will stop using these advisories once the growing season ends, usually after a series of freezes or a hard freeze (28°F or colder) occurs.

Due to the colder-than-normal weather in September in central and north-central Wisconsin, advisories for frost and freeze conditions are suspended until next spring. However, Frost Advisories and Freeze Warnings will be issued, as needed, for the Fox Valley and lake shore counties through at least the first week of October.

Coordination of frost and freeze headlines has been made with surrounding NWS forecast offices.

The maps below (courtesy of the Midwestern Regional Climate Center) show the dates of when freezing temperatures have occurred this fall, in addition to when the average first freeze is.
