August RecapTemperatures were above normal the past few months but that trend reversed itself in August with a slightly cooler than average month, despite reaching 98° for the highest temperature of the month. In fact, most of the month saw daily temperatures within a few degrees of average (above or below), but a several days of well below normal temperatures from the 20th-28th contributed to the below normal monthly average.
Precipitation was above average for the driest month of the year climatologically, but was concentrated on just a few days. Rainfall of 2.61" on the 5th (a daily record) was about 1/4" short of the normal precipitation for the entire month. Through August, Memphis International Airport continues to narrow its annual rainfall deficit, which now stands at just 1.41", or about 96% of normal.
There was one severe weather day in August, which was the 5th. This day recorded the highest official wind gust for the month as well as record rainfall. Thunderstorms downed trees and power lines and heavy rainfall produced some areas of flash flooding in the metro.
