Then, five days after a record high of 81 degrees, four to six inches of snow fell roughly along the I-40 corridor on the 11th, followed by a high temperature of 34 the following day. Four days later, Memphis was back up to 70 degrees and another stretch of warm days ensued. cooler than average weather moved back in for the last week of the month. The average temperature for the month ended up 1.0 degrees above normal, driven by the average high temperature which was 2.5 degrees above average.

In addition to the snow storm (which also featured some thundersleet!), thunderstorms occurred on the 6th, 22nd and 30th. The storms on the 30th brought severe wind damage to northern DeSoto County, southern Shelby County, and southern Fayette County, as well as Tornado Warnings. Tree and power line damage occurred as a result of wind, and a wall collapsed on a warehouse in Southaven, MS (DeSoto County).
