• The table and chart summarize the date when temperatures of a given threshold are expected to be reached. The graphic depicts the median date of the first 32F

temperature across the Midwest, with the chart providing a more in depth comparison across the Aberdeen CWA. For example, in Aberdeen, the average (or mean) date when temperatures are first expected to fall at or below 32F occurs on September 22nd. Similarly, 90 percent of time, temperatures in Aberdeen will have fallen at or below 28F by October 15th.
