Volume 14, Number 1 - April 2022

As mentioned in March’s climate report, April is the most active month for severe weather. This April was no exception with 20 tornadoes, 18 hail, and 62 wind reports (preliminary). Through April, Alabama has reported 68 tornadoes which is above the 30-year average (1991-2020) of about 50 tornadoes annually. Fortunately, no one was killed from the tornadoes that occurred during the month of April.

From a statewide temperature perspective, April’s monthly average temperature and monthly average daily maximum temperature equaled their long-term averages of 62.8°F and 75.6°F, respectively. The monthly average daily minimum temperature of 49.9F was slightly cooler than the long-term average of 50.1 F. April had multiple swings of warm and cold temperatures throughout the month which is typical for spring. During one of those warmer temperature swings, the Andalusia-Opp airport recorded the warmest location of the month at 91°F on the 25th. This station is also the only station to record a temperature of 90°F or warmer this April. Through one of the colder stretches, the station in DeSoto State park recorded the coldest location of the month at 27°F on the 10th.

Overall, the monthly rainfall was close to average statewide, where 5.24 inches of rain accumulated across the state, only 0.43 inches above the mean. However, the rainfall was not uniform across the state. Central/south-central/southwest Alabama recorded above normal rainfall with a station in Toxey, AL recording the most rainfall of the month at 9.64 inches. In contrast, the driest areas of were located in northeast/southeast/coastal Alabama with a station in Midway, AL recording the driest location of the month at 2.29 inches of rainfall (with less than five days of observations missing).

Summer is just around the corner, so is hurricane season. June 1st is the official start of the Atlantic hurricane season, although we have seen in recent years that tropical systems can develop during the month of May. Atlantic hurricanes tend to be more frequent during La Nina patterns. Given that we are currently in a La Nina pattern and this pattern is forecasted to continue, now may be a good time to review your severe weather plan for this summer and fall (mid-September is the peak of hurricane season).
