CWG readers predict 42 90+ days in Washington, D.C. by the fall


Distribution of predictions for 90+ days from Capital Weather Gang readers

This number is slightly lower than Capital Weather Gang’s prediction of 45-50. The range of submissions spanned 4 to 105. Since 1980, the most 90+ days to occur was 68 in 1980 and 2010, and least was 11 in 2004.

The above chart displays a histogram which gives a good general sense of the grouping of predictions.

Interestingly, reader forecasts had a tendency to fall into a range either just above (41 to 50) or below (21-30) the historical average number of 90+ days, rather than average itself - which is 36 (or between 31-40).
