Even though the annual temperature was the warmest since 2017, it was still cooler than than the 30-year average. There was an 82-degree temperature range during the year, with the highest temperature reaching 99 degrees (September 6th, August 13th, and August 7th), and the coldest temperature falling to 17 degrees (November 13th). This was the first year in two years with no 100-degree days at Little Rock. Since temperature records began in Little Rock in 1879, this year is only the second time the coldest temperature for a given year was recorded in the month of November. The only other year this occurred was in 1891, when the coldest temperature occurred on November 29th. For the second year in a row, rainfall was frequent and excessive. While the year wasn`t in the top ten wettest, it did end up at 25th wettest. There were 110 days with measurable rainfall (that is rainfall of 0.01 inch or more). This is the fewest number since 2017. There were five months with a rainfall deficit (March, July, September, November, December), and seven with a surplus (January, February, April, May, June, August, October). The wettest month was April, and the driest month was September. Snowfall was below average for the third consecutive year. Snow fell in January, February, March, November and December, but was not measurable. This was the first year with no measurable snowfall at Little Rock since 2001, breaking a 17-year streak with measurable snowfall that started in 2002. 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.
