Frost Dates for 71837 — Fouke, Arkansas

Half of springs at Texarkana Webb Field, AR see their last 32°F night by March 13; only one in ten is past it by February 23, and one in ten still has one after April 3. Planting tender crops after March 21 leaves a 30% risk of a frost on them, after March 27 20%, and after April 3 10%. The 21 days between the even-odds date and the one-in-ten date is wider than at 97% of the 105 Arkansas stations behind this site's ZIP pages, so a fixed calendar date is a gamble here.
