Here’s a website which lists sources of information on weather and climate in the National Weather Service’s Southern Region.  It includes a number of decision support tools, data sets, and other information for areas from New Mexico through Georgia and Florida.  You can see it at https://www.ncdc.noaa.gov/rcsd/southern.  If you are in the Carolinas, you can replace the word “southern” with “eastern” in the link above and get to the appropriate web site.
