According to Dr. Mark Seeley, University of Minnesota professor emeritus and meteorologist, we can expect new normals in the last spring frost date for Minnesota. In his March 29th program on MPR Weather Talk radio, Dr. Seeley said in the last 20 years, April 20th was the average date for the last frost . The years 2019-2020 still need to be added to the new historical data (1991-2020) that will come out in late 2020 or 2021, but “for now we can see that the new median spring last frost date is shifting much closer to April 20.”

Thank you for the info, but I was wondering when is median first frost in Fall?

This is the best I can do. We do not have that information on Extension. Put in your own zip code: https://davesgarden.com/guides/freeze-frost-dates/index.php?q=55432&submit=Go
