671 FNUS55 KPIH 050809 FWFPIH Fire Weather Planning Forecast for Southeast Idaho National Weather Service Pocatello ID 209 AM MDT Fri Jun 5 2026 .DISCUSSION... * Central Idaho Dispatch Area weather impact summary (Zones 475 and 476)... Very weak high pressure over the area this morning leads to a very quiet start to the day. However, we will see wind gusts increase this afternoon ahead of our weekend system as a very slow-moving cold front begins to move into the area. Gusts today will range from around 30 to 35 mph with stronger gusts on ridge tops. It is still very dry out there, too, with NEAR CRITICAL fire weather conditions. RHs will increase a bit this weekend, temperatures will decrease, and we will see an increasing chance for a wetting rain on Sunday. A more robust system still looks to be on track to arrive Tuesday into Wednesday of next week. * East Idaho Dispatch Area weather impact summary (Zones 410...411 and 413)...
