Hydrologic Outlook issued June 1 at 1:06PM MDT by NWS Riverton WY
ESFRIW Temperatures are expected to reach the upper 80s to low 90s across many locations Sunday. 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. With the expected warm temperatures, a significant portion of that high-elevation snowpack is expected to continue to melt through Sunday night. Minor flooding of small streams and creeks
