...Data for North Little Rock for September 2017...

.Summary...
Unfortunately, our luck with below average temperatures finally ran
out. The first two weeks of the month saw daily temperatures up to
10 to nearly 15 degrees below average. However, the trend completely
reversed in the latter half of the month, and September 2017 in
North Little Rock ended up a degree above normal.

There were 12 90-degree days, which was the fewest in the month of
September since 2015. There were four days with low temperatures
below 60 degrees, which was the most since 2015.

Rainfall was significantly below average. There were only two days
with measurable rainfall, and amounts on those days were less than
one quarter inch. This made for the driest September in 13 years,
and the driest September since records began at North Little Rock.

.Monthly Temperatures...
The average high temperature was the coolest since 2012. The average
low temperature was the coolest since 2011. The average monthly
temperature was the coolest since 2014.

.Daily Temperatures...
Daily temperatures were above average on 17 days, below average on
12 days and average on one day.

.Daily Record Temperatures Tied or Broken During the Month...
Date  Record Type               New Record          Previous Record
 6th  Coolest High Temperature  75 in 2017            78 in 1988

.Monthly Rainfall...
September 2017 was the driest since 2004, and the driest on record.
The previous record was held by 2004, with 0.33 inches of rain.

There were only two days with measurable rainfall, which was the
least on record at North Little Rock in the month of September since
records began in late 1975.
