Climate Central has produced an easy to use map which provides color-coded information about trends in temperature across the country.  You can find it here.  It’s interesting to see how the trends change by region as well as season.  In the Southeast, the highest warming trends have been occurring in winter and summer, with less in spring and fall.  Keep in mind that these are only trends since 1970, and if you go back farther in time the trends in the Southeast, at least, are smaller due to warm conditions earlier in the 20th century.
