Another nice day
We'll keep this trend of above average early fall temps going through the day Wednesday, then we'll level things out to low 70's and then a shortwave brings temps down to the 60's. It's the weekend that will be a losing proposition. Average chances of rain/storms is 50%.
Wind today will pick up from SSW 10-20+ mph. Mountain showers show up Wednesday for Salmon and the wake of that will take the heat off. Normal highs is 71 in Idaho Falls and mornings in the low 40's. Chilly start to the days and still popping 76 for today. Sunglasses and hoodies and shorts if your kneecaps match, or not.
Keep in mind precip varies but there may 1/2" of wet weather for the valley Sat/Sun and we may see some high snow. I think the autumn weather is fixing to settle in.
