December Climate Recap
The month of December was marked by a series of frontal systems that brought large temperature swings and periods of wet weather. After starting very warm, multiple days of cool weather followed a front that brought about an inch of rain. Despite a couple of warmer days, temperatures were a bit below average from the 5th through 15th. Another warm and wet spell resulted in several inches of rain in the third week of the month. As Christmas approached, temperatures dropped precipitously with well below average conditions experienced through the final week of the month. That week put the nail in the coffin of a colder than average month with above normal rainfall that nearly put the year right on par for precipitation. Despite the very cold temperatures at the end of the month (the period from Christmas to New Year's Eve was the 12th coldest on record), the only record set was a daily rainfall mark, eclipsed on December 22 when over 3" of rain fell. Flash Flood Warnings were issued for portions of the metro on that day, otherwise no severe weather occurred during the month.Memphis International Airport, Memphis, TN
