ESFRIW Temperatures are expected to reach the mid to upper 80s this weekend. Sunday will be the warmest day, with highs in the upper 80s to low 90s across many locations. Low temperatures will also remain well above freezing with low temperatures in the 40s at elevations above 9500 feet. These warm temperatures will continue to lead to an increase in the rate of mountain snowmelt. Most mountain snowpack below 9500 feet has melted out, however, high-elevation mountain snow water equivalent (SWE) above that level still remains.
