May Climate Recap

Following in April’s footsteps, the month of May was warmer than normal by over 2 degrees, as was repeated across most of the eastern U.S. In fact, all but six days in May were warmer than average. However, extreme heat did not occur, as Memphis did not reach 90 degrees during the month, despite the average first 90-degree day typically occurring in mid-May. The warmth was primarily driven by overnight lows averaging nearly four degrees above average, including tying two record warm minimum temperatures a week into the month.

Rain fell about every other day with a few severe thunderstorm threats and large variability in total rainfall in the area, driven by localized heavy rains. Severe weather occurred on multiple days, particularly in the last ten days of the month, including reports of hail and wind damage across the greater metro.
