Weekend will bring a little relief from the concentration of smoke across southern Idaho. A weak system will work across the region, and this will change our winds from the dry northerly and easterly winds we’ve had to more of a southerly flow. This cuts off the flow of smoke we’ve been experiencing and push some of the old smoke away. While it is some relief, it won’t remove all of it.
We could see spotty showers and storms on Saturday and it will be cooler, temperatures in the middle 80s for the valleys and middle to upper 70s in the mountains.
While there is a chance of rain, they are very spotty and a lot of you will remain dry, but any rain could help cleanse the air. The only down side with the rain is some could be thunderstorms with lightning, which could spark a few isolated fires in our region.
By Sunday, the chance of rain passes, we will return to dry conditions. Temperatures won’t be as high, but smoke could filter back into the region as a weak area of high pressure returns for the end of the weekend and early next week.
