Volume 13, Number 3 - June 2021

June marks not only the start of climatological summer, but also the third consecutive month that Alabama was cooler and wetter than normal statewide. In fact, this June was the 5th wettest June on record with 4.31 inches of rainfall above normal.  

The majority of the rainfall for much of the state (excluding NW Alabama) was due to tropical storm Claudette from June 18th to June 20th. Numerous daily precipitation records for the month were broken with this tropical storm. The most noteworthy new records were the Tuscaloosa Oliver Dam station (122 years of observations) at 6.58 inches of rainfall on the 20th and the Birmingham station (127 years of observations) at 4.36 inches of rainfall on 19th. In addition to the daily record, Tuscaloosa Oliver Dam also recorded their wettest June on record at 14.83 inches of rainfall. A station in Oakman, AL recorded a staggering 21.45 inches of rainfall which was the most of any station this month and all time monthly record for this location, although it has only been operating since 2017. Several other stations across the state recorded their wettest June as well. This tropical system along with the widespread heavy rain produced three tornadoes that impacted Escambia, Conecuh, Covington, and Mobile counties.

As is the case more often than not, a wet month also means a month that is cooler than normal. Statewide, June was 0.5°F below normal with respect to the average temperature. However, if we analyze the daily high temperatures and daily low temperatures, we find that statewide the average daily high temperature was 2.5°F below normal and the average daily low temperature was 1.4°F above normal. This is expected since the above normal rainfall limits how hot daily high temperature can rise to and limits how cold daily low temperatures can drop to mainly due to the cloud cover and moisture. It also reflects the larger scale weather pattern that produced very hot temperatures in the West and cooler temperatures in our area.  However, Alabama still can get hot and almost 30 stations topped the 95°F mark at least once this month with the Andalusia Opp Airport station recording the hottest spot of the month at 100°F, the first 100°F mark of the year!
