January 2017 Climate Data for Memphis, TN

January Recap

After December broke a streak of six consecutive months ranked in the top 10 warmest for their respective months, January returned to the top 10 rankings, tied for eighth warmest January on record.  The warmth lasted nearly all month with just one spell of multiple days that were well below average temperature-wise, which also coincided with the first significant snowfall of 2016-2017 winter on the 6th. That early-month cold spell featured four consecutive days with high temperatures at or below 35 degrees and a couple of morning lows in the lower teens. However, three days later, highs were back above 70 degrees. After the 9th, only two days featured average temperatures below normal, and those were 1-2 degrees below an "average" day.

Warmest Januarys on record in Memphis, per the National Weather Service. 2017 tied for 8th warmest.
Precipitation was just a bit above normal at the airport, but below average at MWN in Bartlett with more than an inch and a half less than the airport recorded. Snowfall officially totaled 2.0" at the airport with reports across the metro varying from just under an inch to about three inches. No severe weather was reported and only one warning was issued, a Flash Flood Warning for far southern Shelby County and far northern DeSoto County on the 10th, which also happened to be the wettest day of the month as storms trained along the TN/MS border.
