In all charts, Max Data is the latest measurement from the database. This Week, or this whatever time period, is the date the chart was generated.
Variance between the two indicates that either data for the current day is not available in the database for some reason (if This Week is later than Max Data) or someone went back in time and ran the chart scripts before the data were loaded (if This Week is earlier than Max Data).

From weather.gov

Degree days are based on the assumption that when the outside temperature is 65°F, we don't need heating or cooling to be comfortable.
Degree days are the difference between the daily temperature mean,
(high temperature plus low temperature divided by two) and 65°F. If the temperature mean is above 65°F, we subtract 65 from the mean and
the result is Cooling Degree Days. If the temperature mean is below 65°F, we subtract the mean from 65 and the result is Heating Degree Days.

For now we simply subtract the daily average temperature from 65, where negative values represent cooling degree days. The plots confirm cooling
days occur in the summer and occasionally in the fall

Two different elevations for each station are shown in the table. Elevations from the US National Elevation Dataset appear to be the most accurate.
