May Climate Recap

After cooler than normal temperatures in April, May continued the trend, featuring only one day with a high that reached 90 degrees and an average temperature that was more than two degrees below normal. The coolest portion of the month, relative to normal, was a week-long spell from the 6th-12th that averaged 12.5 degrees below normal with highs in the 60s and a few lows in the low 40s. The first quarter of the year was wet, but drier weather from April continued in May with only 2″ of rain recorded for the month. Nearly half of that fell on the 8th. 

Severe weather was limited in May. There were two events that resulted in severe weather reports. A thunderstorm on May 3 produced penny size hail in northeast Shelby County. A much more destructive event, on the afternoon of May 22, produced widespread damaging wind across Crittenden and Shelby Counties. Tress and power lines were downed from a wind storm that tracked across the area from AR. Over 52,000 Memphis Light, Gas and Water customers in Shelby County lost power in the storm as the Memorial Day weekend started.
