NOAA’s Climate.gov blog has a good discussion of the mid-March freeze event by Jake Crouch. It describes how it fits into historical context both with the warm winter that preceded it and the comparison to average last frost dates.  It also describes what damage it caused, both to peaches and blueberries as well as pastures. You can read the post at https://www.climate.gov/news-features/blogs/beyond-data/bad-news-southeast-peaches-something-freezing-way-came.
