Frost risk by date in Powderly
Half of springs at Paris, TX see their last 32°F night by March 14; only one in ten is past it by February 24, and one in ten still has one after April 2. Planting tender crops after March 22 leaves a 30% risk of a frost on them, after March 28 20%, and after April 2 10%. The 19 days between the even-odds date and the one-in-ten date is narrower than at 63% of the 339 Texas stations behind this site's ZIP pages.
