...Additional Data for Little Rock Adams Field for Fall 2017...

.Summary...
Though temperatures for the season were above average, it was still the
coolest fall in three years. This fall included the earliest snowfall on
record, and the earliest freeze in 28 years.

.Seasonal Temperatures...
The average high, low, and seasonal temperatures were the coolest since
2014. There were 13 days with high temperatures of 90 degrees or higher,
which was the fewest since 2014. There were five days with low temperatures
at or below freezing, which was the most since 2014.

The first freeze of the season occurred on October 28th. This was the earliest
freeze at Little Rock since 1989, and was the 8th earliest on record.

The coldest temperature of the fall season was actually in October instead of
November. This is the first time in 100 years (since 1917) this has occurred
at Little Rock. Since temperature records were started in Little Rock in 1879,
this has only occurred three other times...1917, 1913, and 1910.

.Seasonal Rainfall...
There were 14 days with measurable rainfall. However, it was significantly
below average, with a deficit for the season of over 11 inches. It was the
driest fall since 1874, and the 2nd driest fall season on record behind
1874.

.Seasonal Snowfall...
Snow fell for the first time during the fall season since 2014, as a
trace of sleet was recorded on the evening of October 27th. Though
it was not measurable, it still was the earliest snowfall at Little
Rock since 1925, and set a new record for the earliest snowfall ever
recorded at Little Rock. Previously, the record had been a trace,
which fell on October 28, 1925.
