April Climate Recap

April will be remembered as much cooler than average with temperatures over six degrees below the climatological average. In fact, the month featured one sub-freezing morning low (30 degrees on the eighth) and a monthly high of only 80 degrees (just four days after the 30-degree reading in fact)! The overall average temperature ended up third coldest on record for April.

Precipitation was above normal as well, totaling nearly eight inches for the month. Again, heavy precipitation was not uncommon as there were only 9 days with rain but a few heavy rain events, including three with more than an inch and one (the 14th) with three inches of rain. Also due to the cool temperatures, the normal start of severe weather season was delayed as there were no severe reports during the month and only two Severe Thunderstorm Warnings in the metro, on the 3rd and 4th in norther MS.
