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

Hydrologic Outlook issued May 27 at 12:12PM MDT by NWS Riverton WY
ESFRIW Showers and thunderstorms will continue to develop over Johnson County this afternoon and evening. Weather models depict a nearly stationary boundary, focused on the eastern foothills of the Bighorn Mountains. With precipitable water values in the 0.7 to 0.8 inch range, which is well above normal, it's worth watching this area for training storms and isolated flash flooding. There is a low chance for flooding in any given location, but the low-end potential is there today given the ingredients present. By midnight, thunderstorms and higher rainfall rates are forecast to end, but light rain lingers through sunrise Wednesday, with
