Below is an analysis of the Capital Weather Gang’s “Daily Digit”, a number from 1 to 10 given each morning to the day’s expected weather. 574 days worth of Daily Digits were analyzed, from March 19, 2013 through October 13, 2014. The starting date was picked as that was the first date where it was easy to get a copy of the CWG’s archived web pages.
The mean daily digit was 6.32.
Below is a trend graph of the Daily Digit, smoothed slightly to make it more readable:
The slope upwards over time could be an artifact of the range of dates chosen, or it could be genuine Daily Digit Inflation.
Below is a histogram of the Daily Digit values:

There is a fairly regular rotation of authors, each generally writing on the same day, hence the strong correlation between the above two graphs. Each author had between 73 to 81 posts.
Not included in the above were the following two authors with a limited number of Daily Digits:
Kathryn Prociv: 10 entries with a mean of 8.3
Rick Grow: 8 entries with a mean of 5.0
There were also a few cases where two authors were credited the same day, also not included above:
Matt Rogers;Jason Samenow: 3 entries with a mean of 3.33

A. Camden Walker;Ian Livingston: 1 entry with a mean of 2 (January 10, 2014, Freezing Rain)
