June Climate Recap
The months of April and May were cooler and drier than average, and that trend continued for much of June. 17 of the days in June were below average and only five days were above average by more than two degrees, resulting in an average temperatures that was a degree below average for the month. The first 90 degree reading of 2021 finally occurred on June 11 (18 days later than average). The number of 90 degree days was right at average, however.
Precipitation ended the month 0.75" above average at 4.74", however 88% of that rain fell in the first nine days of the month. Just south of the border, flooding occurred in the first week of June as up to 6+ inches of rain fell. By the end of the month, prior to a decent soaking on the 30th, abnormally dry conditions were found across the area, particularly north of I-40 where rain early in the month was much less than at the airport. (Just over 2 inches was recorded at MWN in north Bartlett.) The only severe weather of the month occurred from the afternoon of the 8th into the 9th when very heavy rain occurred mainly along and south of the TN/MS state line. Flooding was reported south of the immediate metro in north MS. About 2.5" of rain fell at the airport, but reports of 6-12" of rain were received to the south.
