July Climate Recap
After consecutive months of below average temperatures, an anomaly in recent history, July moved back above average, but just barely. The average temperature of 83.1 degrees was about one-half degree above normal. The month as marked by a very hot spell in the third week of the month with mid to upper 90s on several consecutive days and Excessive Heat Warnings posted as heat indices climbed above 110 degrees. Slightly cooler than average weather started and ended the month.
Precipitation was fairly variable across the metro due to the nature of summertime thunderstorms. To wit, Memphis International Airport ended up with just under 4″ of rain and at a deficit for the month, while MWN in Bartlett recorded over 5″, which was above the July average. Most of the rain fell in the early and latter stages of the month with a hot spell mid-month resulting in little precipitation. Another example of the sporadic nature of the precipitation lies in the storm reports for the month. Flash flooding was reported in multiple locations in the metro on the 15th, yet both Memphis International Airport and MWN recorded no measurable precipitation for the date. A couple of hail and wind reports were recorded with pulse thunderstorms on various days of the month but no widespread severe weather occurred.
