April 2021 Climate Report for Memphis, TN

April Climate Recap

While March was much warmer than average, April cooled down a fair bit relative to average, ending almost two degrees below normal. While there were several days of above average warmth, only a couple were excessively so. On the other hand, there were several days were it was abnormally cool, including a few days with morning lows in the 30s to start the month, and another particularly cold shot centered around the 21st, when frost occurred again and high temperatures were quite cool. A daily record low was set on the 22nd with a minimum temperature of 37 degrees. As usual though, a wide range of temperatures occurred, from a few lows in the mid 30s to a few days with highs in the mid 80s.
Precipitation ended well below average (56% of normal), even though there were several days with rain, as only one day recorded more than an inch of rain. In fact, two-thirds of the total April rainfall fell in the last week of the month. Surprisingly, in what historically is one of the busiest months of the year for severe weather, no severe weather reports were received and only a couple of weather warnings were issued in the metro during the month, on the evenings of the 7th and 9th.
