April 2020 Climate Data for Memphis, TN

April Climate Recap

April turned the corner from the warm winter and early spring as temperatures averaged below normal for the first time in a while. High temperatures were the primary contributor, averaging more than three degrees below normal. Only two days in April reached 80 degrees, compared to three in March. Breaking from the very wet streak of the first quarter of the year, April rainfall came in right at average with nearly one half of the total rainfall for the month occurring on the 12th when some reports of severe weather were also received.

Severe weather occurrences were on the evening of the 8th in Fayette County with some wind damage, the evening of the 12th across the metro as trees and power lines were felled by strong wind, and on the night of the 28th-29th across the southern sections of the metro, including northwest MS. Strong wind was again the primary severe weather phenomena.
