It's really hard to listen to the weather in Montana. If there's a big storm coming they alert the whole state. And, much like Illinois, it's possible for more than one weather system to be affecting different parts of the state at one time. It's like someone from Chicago getting a weather advisory for Memphis Tennessee.
It's an interactive blog today... compare:
Plevna Weather to Bozeman Montana.
(Okay, when I did this I really thought the two places would be very different, but right now they're not. Maybe by the time you click on it things will have changed. Post a comment if they are.)
