Half of springs at Sheridan, AR see their last 32°F night by April 1; only one in ten is past it by March 11, and one in ten still has one after April 17.

The 16 days between the even-odds date and the one-in-ten date is narrower than at 65% of the 105 Arkansas stations behind this site's ZIP pages.
