May Climate Recap

Temperatures for May were generally below average for the first half of the month and above average for the second half, ending about 2 degrees above normal for the entire month. Of the first 14 days, 9 featured below average temperatures. After the 14th, there were no days with below average temperatures as the heat was turned up and highs in the 60s and 70s were replaced by 80s and 90s. In fact, an average May has two days that top out at or above 90 degrees. This year, 7 out of 8 days between May 21-28 reached 90 degrees.

Following the trend in temperatures, precipitation for the month ended near average, but the month could easily be split about in half. May started wet with all but 0.10″ of precipitation falling in the first 18 days of the month. Measurable rain only fell on one day for the remainder of the month with no measurable precipitation after the 22nd, at least at the airport. This resulted in soggy conditions through roughly the first third of May (3″ of rain fell on the 8th-9th), a bit of drying in the middle third, and very dry conditions for the final third of the month.

Thunder occurred on six days at Memphis International in May, typically an active severe weather month. However, severe weather only occurred on two days of the month. Several hail reports, up to half dollar size, were received on the afternoon of the 15th. Then, on the evening of the 18th, a severe storm moved across the river, downing trees and power lines and cutting power to tens of thousands. An anemometer mounted at 35 feet in Tom Lee Park measured a wind gust to 59 mph. Severe Thunderstorm Warnings were issued on both days.
