Fruit trees need a set number of cold hours in winter before they bloom well. Nurseries rate varieties by it: low-chill varieties need roughly 100 to 400 hours, many peaches and plums 500 to 900, and most apples and sweet cherries 800 to 1,200 or more. Your variety's rating is the number to compare with the 1,427 hours Siloam Springs had last winter.
