...Data for Harrison for Fall 2018...

.Summary...
While temperatures during much of the fall were above average, that
all changed in November. This caused the entire season to end up
slightly below the 30-year average, and this was largely due to cold
high temperatures during November.

Rainfall ended up being below average, but by just under an inch.
This was largely due to deficient rainfall in September and through
much of November. Even so, it was still the wettest fall in three
years.

This was the first fall in four years with measurable snowfall.

.Average Temperatures...
The average high temperature was the coldest since 2002. The average
low temperature and seasonal temperature were both the coldest since
2014.

.Rainfall...
This was the wettest fall since 2015.

.Snowfall...
This was the snowiest fall since 2014. There were two days with
snowfall, measurable or not, which was the most since 2014.
