Fall 2011 Summary

A very warm fall that was also the wettest on record

The fall was over 2.5 degrees warmer than average, the heat was very consistent throughout the entire season except for a relatively cool week at the end of October. But even for that week it was only 3 or 4 degrees colder than average compared too many days that were more than 5 degrees warmer throughout the fall. However, as we have seen many warm falls in the recent past, we only have to go back to 2001 to find one that was hotter.

It was a very wet fall with 349.2 mm of total precipitation compared to the average of only 218.1 mm. This was the highest fall precipitation I could find, just beating out 1955 which had 339.5 mm.

There was only 5 cm of snow recorded this fall which is much less than the average of 30 cm. The fall of 1998 was the last time we have seen anything like this, as that year we only had 2 cm.
