Idaho we have made it to the weekend but it is not as nice as this Summer has been. Heat and haze are both apart of the weekend forecast. Thunderstorm activity is also expected soon.
Smoke from a few fire north of McCall are producing a lot of smoke for the Gem State so prepare for haze over the next couple of days. Hopefully the next weather pattern moving in will knock some of the hazy skies down.
Smoke, mainly from the Island Creek Fire located near Elk City, is expected to spread southward across much of SW ID late tonight, affecting most of the area through Sat. Anticipate reduced air quality and hazy skies, especially during the morning hours. pic.twitter.com/0f9W97r8lj

Saturday is seeing chances of triple digits for the Treasure Valley so try to stay cool. Temperatures fall slightly but stick to the 90's up until Wednesday. That is when we start to see a shift in the forecast.
Showers are expected to move into large parts of Idaho with a dip into the 80's for daytime highs. The southern border closer to Twin Falls will get the most activity over the next week so eyes will be on how storms impact the Magic Valley going into the work week.
Have a great weekend and here is your extended forecast:
