This appears to be the last weekend to really go out and enjoy warm weather activities for the rest of 2019. It is officially the last weekend of summer, as the fall equinox occurs late Sunday night. But it may be the last really nice weekend for those summer activities: Temperatures will be near normal for this time of year, in the 60s and low 70s for most by Sunday. The other images show the outlook for September 28 to October 4. It is highly likely that this week will be colder than normal (indicated by the blue shading over Idaho on the left), with the precipitation very likely to be above normal (green shading over Idaho on the right). The darker the shading, the more confident the forecast.
