Summary =================================================================== Even though the average annual temperature was right at the 30-year mean, 2020 at Pine Bluff was the coolest year since 2014. While lows were the warmest in two years, highs were actually the coolest in six years. Though we saw the fewest freezing temperatures in 21 years, we also saw the fewest 90-degree days in three years which was well below the average of 71. Pine Bluff also saw no 100-degree days for the 5th year in a row. To date, there has not been a 100-degree day reported at Pine Bluff since August 7, 2015. This continues a record streak of 1,973 days with no 100-degree temperatures at Pine Bluff. The previous record was 1,132 days from July 9, 1948 to August 14, 1951. In terms of departures from normal, or (more properly) most above or below average, January and March were warmest, with a departure of +3.9 degrees, and October was coolest with a departure of -2.6. However, going by the averages, the warmest month was July (which is typical for the area), and the coldest month was December (by average, January tends to be coolest). For the third year in a row, rainfall was significantly above average. Even so, the rainfall amount was the least since 2017. That being said, it was still the 17th wettest year since records began in late 1883. There were 136 days with measurable rainfall, which was the most since 2004. February was the wettest month, and November was the driest month. For the fourth year in a row, no measurable snow fell. However, there were trace amounts of sleet and snow in January, February, and December. As of December 31, there have been 775 days since measurable snow fell at Pine Bluff (November 14, 2018). While this is the longest measurable snowfall drought since the January 22, 1989-January 17, 1992 period of 1,091 days, it is nowhere near the record of 1,432 days which occurred from February 21, 1936 to January 22, 1940. ===================================================================== Remember, all data listed below is preliminary until final quality control by the National Center for Environmental Information in Asheville, North Carolina.
