February 2018 Climate Data for Memphis, TN

February Climate Recap

With a wet pattern dominating the weather in February, temperatures also were well above average due to increased moisture content in the atmosphere. For the month, the average temperature was 4.3 degrees above average, which ranks in the 88th percentile for warmth or 17th warmest February on record. High and low temperatures both averaged 4.3 degrees above average, so neither contributed more to the daily anomaly than the other.Three daily records were set or tied during the latter half of the month. Only six days saw average temperatures more than 2 degrees below the climatological average.

Precipitation was the big story for the month with three days recording near or more than two inches of rain, including 1.99" on the 10th, 2.82" on the 21st, and 3.12" on the 28th. Overall, two-thirds of the days in February had measurable rain with an average cloud cover for the month of 80%. With all of the rain came some periods of minor flash flooding, although river flooding at the end of the month into the first few days of June was the bigger impact as the Mississippi River climbed above flood stage and local tributaries such as the Loosahatchie and Wolf Rivers also overflowed their banks.
February 2018 was the in the top 3 wettest on record for ten states that drain into the Ohio or Mississippi Rivers, resulting in flooding late in the month into early March in both basins, including the Mississippi River at Memphis. (NOAA/CPC)
