Half of springs at Fort Worth Meacham Field, TX see their last 32°F night by March 11; only one in ten is past it by February 21, and one in ten still has one after April 3. Planting tender crops after March 20 leaves a 30% risk of a frost on them, after March 27 20%, and after April 3 10%. The 23 days between the even-odds date and the one-in-ten date is wider than at 72% of the 339 Texas stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
