Temperature cycles between 14 and 50 F during the fall season
The featured map is the number of expected fall season temperature cycles between 14 and 50 degrees Fahrenhit. The formulation is that once the fall temperature dips below 14 and then later exceeds 50, that is 1 cycle. The map shows the favored area for these temperature variations is Southwest Iowa with roughly 2.5 cycles expected based on climatology. Values for other temperature thresholds can be found on the climodat page under Freeze/Thaw cycles.
