August 2022 Climate Report for Memphis, TN

August Climate Recap

The heat of late June and July continued into the first week or so of August, before settling in near average for the next couple of weeks. The last week of the month turned to above average once again, with the end result being an average temperature for the month near one degree above normal. However, the average temperature was over four degrees cooler than July! For the period of “meteorological summer” (June-August), summer 2022 ended as the fourth hottest on record, behind only 1980, 2010, and 2011.

Precipitation for the month was fairly abundant in spots, but was beneficial for the entire metro. While nearly 6″ fell at Memphis International Airport, just over 3.5″ fell in Bartlett. The result of more precipitation was very evident in the change in the drought index maps, as shown below. Severe drought encompassed large sections of the metro at the start of the month, but by the end of the month, the worst drought was “moderate” in parts of northwest MS, while drought was completely removed in Shelby County. There was no severe weather during the month, though Flood Advisories were issued for heavy rain a number of times during the month and a Severe Thunderstorm Warning was issued for far eastern DeSoto and northern Marshall Counties on the 21st.
Comparison of the Drought Index from the beginning to end of August shows the results of a good amount of rainfall across the Mid-South, especially in west TN and northeast AR. (U.S. Drought Monitor)
