860 FNUS75 KRIW 170136 FWSRIW Spot Forecast for Bad Water...BLM CAD National Weather Service Riverton WY 736 PM MDT Fri Aug 16 2024 Forecast is based on forecast start time of 2000 MDT on August 16. If conditions become unrepresentative, contact the National Weather Service .DISCUSSION... Clear skies will continue tonight into Saturday morning. Winds, 5-10 mph, will continue through the rest of the night, turning more easterly by 2300. RH recovery will be poor through much of the night, possibly reaching 40% by sunrise. This will lead to critical RH values occurring by 1300. West- southwest winds, 10-15 mph, will return by 1300, as clouds increase from the southwest through the afternoon. There is a small chance (10-20%) for showers and thunderstorms Saturday between 1800 and midnight. The site will be impacted with outflow winds through this time, possibly lingering for several hours into early Sunday morning. A wetting rain could occur, but not likely due to the low confidence in storm chances. RH recovery will be slightly better Saturday night, due to the increase in moisture into the area. Showers and thunderstorms will be possible again Sunday evening. ...Thunderstorms imply strong gusty and erratic winds... ...Haines index is high level haines both day and night... .REST OF TONIGHT...
