We're wrapping up our warmer weather…finally – LocalNews8.com

Another beautiful day here in eastern Idaho and western Wyoming. Initially our forecast will be calm, but later this workweek we expect big changes as a fall cold front moves in.

Sunday, mostly sunny with temperatures remaining above average. Daily highs will peak in the 70s, with some areas possibly reaching the 80s. A light haze is possible in some areas as wildfires continue to burn.

Monday, another fairly sunny day with daytime highs similar to Sunday. Mostly in the 70s, but a few 80s possible too. Here too, some haze is to be expected here and there.

Tuesday, more sunshine with slightly cooler temperatures than Monday. In general, though, for most of us we'll still hit the limit in our 70s. Some smoky haze will still be possible.

The rest of the forecast brings big changes late Wednesday evening as a cold front pushes through. Expect scattered showers and MUCH cooler temperatures. Daily highs will fall from the low 70s on Wednesday to the upper 40s and low 50s on Thursday and Friday. More significantly, Friday night/Saturday morning lows will likely mark an end to the growing season. Expect lows in the upper teens at higher elevations and upper 20s at lower elevations. This is cold enough that it might be worth taking the time to drain/blow out the sprinkler lines before the cold temperatures take hold.
