BOISE, IDAHO — The National Weather Service Boise is forecasting continued gusty wind conditions across southwestern Idaho and adjacent areas through the weekend, with peak wind gusts persisting overnight in highlands and ridgetops Friday night into Saturday as north to northwest flow maintains an active wind pattern across the region.
Peak Wind Gusts Saturday Cover Broad Swath of Southwestern Idaho
The NWS Boise peak wind gust forecast valid Saturday June 13 through June 14 shows widespread wind gusts of 20 to 25 mph across most of the forecast area including Boise, Caldwell, Emmett, and the surrounding Treasure Valley corridor. Isolated yellow shading indicating the highest gusts of 28 to 29 mph is focused across Ontario, Halfway, Grand View, Owyhee, and Jackpot.
Ridgetop locations including Baker City, Sumpter, and higher terrain corridors are also highlighted with elevated gust values reaching into the upper 20s Saturday.
North to Northwest Wind Direction Persists Through the Weekend
Winds will remain out of the north to northwest through Friday night and into Saturday, maintaining gusty conditions particularly across highland and ridgetop terrain. The persistent northerly flow pattern will keep overnight wind gusts elevated across the higher elevations even after daytime gusts diminish across valley locations.
Riggins in northern Idaho carries one of the higher forecast values on the map at 26 mph, reflecting the channeling effects common to that river corridor under northwest flow.
Twin Falls and Southern Idaho Also See Elevated Gusts Saturday
The southern Idaho corridor including Twin Falls, Jerome, Gooding, and Jackpot also falls within the elevated wind gust zone Saturday, with values ranging from 18 to 28 mph across that region. Outdoor activities across the highlands and ridgetops of southwestern Idaho should account for gusty and potentially disruptive wind conditions through the weekend.
