The effects of climate change on freezing rain in Europe under medium (RCP4.5) and strong (RCP8.5) future emission scenarios were assessed using seven regional climate model simulations conducted within the World Climate Research Project's COordinated Regional climate Downscaling Experiment over the European Domain (EURO‐CORDEX). A precipitation‐typing algorithm was applied to modeled three‐dimensional subdaily time series of key meteorological variables to estimate the occurrence and amounts of freezing rain above selected intensity thresholds. The annual probabilities of freezing rain during the baseline (1971–2000) and future (2071–2100) periods were calculated. The models agree that under the RCP8.5 scenario, the frequencies of freezing rain decrease in western, central, and southeastern Europe by 20–55% and increase in the northern and northeastern parts of the continent by 0–50% toward the end of the century. In the northern regions, the peaks in spring and fall with freezing rain amounts during the baseline period tend to merge to a single peak in winter during the future period. Under the RCP4.5 scenario, the changes are qualitatively similar but smaller.
