...A Review of 2016 Weather And Climate Data for Little Rock Adams
Field...

Summary
====================================================================
2016 at Little Rock was the warmest year since 2012, and by average
yearly temperature was the 3rd warmest year on record. Even though
rainfall was above average, it was the driest year in two years.
Rainfall was above average for the second year in a row.

Temperatures were warmer than average for just about the entire year.
The only significantly cooler periods were in May, and in December. By
departure from normal, March was warmest, and May was coolest.

Rainfall was mostly below average through the first couple of months.
However, this completely reversed in March and continued through April.
Over 20 inches of rain fell during this time period, ensuring the spring
season as one of the wettest ever recorded. Rain picked back up in middle
of summer, and July and August ensured that summer was, like the spring,
one of the wettest ever recorded. Rain diminished significantly in
September, with the fall season the driest in 63 years.

Snowfall was above average for the third year in a row. However, all the
measurable snow during the year came from one storm. Heavy snow fell in
central Arkansas during the overnight hours of January 21st and 22nd, with
over five inches. Except for trace amounts in mid-December, there was no
other snowfall during the year.

Below are averages and extremes observed during the year. Remember...most
of the data below is preliminary until certified correct by the National
Center for Environmental Information in Asheville, North Carolina.
