Temperatures in the Central Appalachians region (and across the broader Northeast) are projected to increase on average by 5.27 to 9.11 °F by the end of the century (2070 to 2099), with the greatest warming expected to occur during summer and fall. More warming (9.11 °F) is projected under a high climate scenario (RCP 8.5) and more moderate warming (5.27 °F) is projected under a moderate climate scenario (RCP 4.5). Studies from across the Midwest and Northeast consistently project 20 to 30 more hot days per year by the end of the century. The frequency of multi-day heat waves is also projected to increase by 3 to 6 days. The frequency of cold days and cold nights in the Central Appalachians is also projected to decrease by 12 to 15 days by the end of the century.
