November 2022 Climate Report for Memphis, TN

November Climate Recap

Temperatures for the month of November in Memphis averaged just below normal, though about two-thirds of the month was actually above normal. The average was skewed down by a 10-day cold snap mid-month with multiple days 10-16 degrees below average, several of them sporting highs only in the 40s. That also drove up the number of sub-freezing mornings we experienced, with 11 days at or below 32 versus an average for November of about four.

With slightly below average precipitation recorded, minor drought conditions continued through the month, and actually worsened slightly for Tipton and Fayette Counties (from abnormally dry to moderate drought). East AR remains in severe drought as we head into December. The wettest day of the month was on the 5th when thunderstorms moved through the area. The cold spell mid-month was primarily dry, before multiple wet days occurred in the last week of the month, though not with excessive rainfall. A little over an inch fell with additional storms on the 29th. These storms also brought hail to southern Shelby County and sporadic wind reports south and east of Collierville. Severe Thunderstorm Warnings were issued.
