The preliminary maps for May 2018 show that temperature was well above normal for most of the region except for the Florida peninsula. Precipitation was above normal for most of the Southeast except for far western regions of the area. A lot of that surplus rain fell in the last two weeks with a plume of tropical moisture that brought copious rain to the region, along with the additional flooding rain from Alberto near the end of the month.
For spring (March through May), temperature was below normal in most places. This is because March and April were much colder than normal than normal, balancing out the warm conditions in May. Precipitation was above normal in most of the region except for a few scattered areas in southern Alabama, southeast Georgia, and the central Carolinas as the far western counties in the Appalachian Mountains.
