Frost Depths in The Upper Midwest

UW Soil Science

The UW Soil Science Department also maintains up-to-date archives of climate and soil data from around the state.

Textual HYD Reports from the Co-Op Observer Network

The maps from the River Forecast Center use data from the National Weather Service's cooperative weather observation network with 700-plus observers around the state. These data are reported daily, and the NWS cautions that they have not yet been quality-controlled when first published. In the winter months, soil temperature and frost depth reports are included for a few locations around Wisconsin (scroll to the bottom of the report). You can access the latest report from the Soil Science archive, which is in a scrolling calendar format; click on the appropriate day in the calendar to see the report.
