I am not an expert on Idaho geography, but when I put Burgdorf into the NWS webpage for a forecast, it shows that area is served by the Missoula, MT office. The above link is to their climate page where you can get monthly reports for some of their cooperative observers. Take a look at the Idaho options in the dropdown menu on the above link. Hopefully, one of them is close to where you need.
I bet cooler temps and a little snow this weekend will get them fired up. I am just trying to see what it is usually like compared to last year. The locals said it was way wetter than normal
