Thanks again for providing us with this opportunity to see P-O-R-N that won't get us into much trouble. Just sayin ... some of you folks are going all in, good luck, if you're right, lots of storm contests.

Do you have any easy access to this statistic -- mean forecast vs mean actual over a long period of time? That would be interesting. I wonder if the group has any recognizable bias with relation to outcome?

Most years ... most forecasters are bullish to one degree or another. Some way more than others. This year: cray-cray!!

The Contest's season-total forecaster and outcome data are stored in one Excel workbook going back to Winter '04 / '05. The three earlier years are available; however ... the format and station lists are different.

Had there been better foresight back in the day ... these data would have been put in Access ... then all kinds of queries could be run. Had no idea the Contest would have such a long life.
