What a nice way to round out the last week Summer with a taste of Winter for our Ida”Snow” ski areas. This week brought the first snowfall of the season across the state beginning on Tuesday and several more reruns through today. Our neighbors in the Tetons and Bitterroot Ranges further east saw a couple feet of snow that closed mountain passes and delighted snow lovers. Overall, what became the season ending event for our mountain wildfires, is now the season starting event to re-charge the soil moistures. Unfortunately, this pattern won’t last because a warming trend is on the way for next week.

I’m dusting off the keyboard, eager for another year of snow forecasts. For those who are new to Idaho Daily Snow, here’s what this is all about. Be sure to share with friends and get your OpenSnow All-Access Pass now so you don't miss any powder alerts.
Today through Sunday
It’s not unusual for us to get snow in September, but this system has hung around quite a while and brought several days of mountain snow showers down below the 6,000-foot level, which IS pretty low for the early season.
The storm will exit the region this weekend, making way for a warming and drying period next week. Here is today’s view from

The switch is going to flip by early next week, back toward weather that is more typical of early Fall thanks to a ridge of high pressure that will build over the western U.S. This will bring mountain temperatures back into the 50s and 60s each afternoon. This pattern will stick around for a while due to a stalling trough over the south-central U.S. Our friends in the Rockies will continue to get high mountain snowfall but the west will be dry.
