Breaking the pattern of the last few fall seasons, we just experienced one that was 0.1 degrees below average but still within the average range. In the 15 years of the records at the UW weather station, we have only had 2 fall seasons that were colder than average.
It was dry for the first few weeks of the fall, then the rest of October was very wet and the rest of season was pretty much average. The total was 282.9 mm compared to the average of 218.1 mm, this is in the above average range, but we only have to go back a couple of years to find a wetter one.
