High-resolution climate models show that the frequency of winter days with very high fire risk (days on which the moisture of 100-hour fuels is in the driest 10 percent of the historical record) has increased by a small amount, around 1 extra day, in the foothills near Boulder, CO. Fall increases are larger. Screenshot from the ClimateMapper tool, a project funded in part by the RISA program in the NOAA Climate Program Office.
