The enemy is dry thunderstorms through Wednesday morning for a good chunk of SW Montana including the entire Bozeman and Livingston areas.

Very dry conditions, consistently hot temps and gusty winds are combining to make any thunderstorm potentially very dangerous. Any wildfires that begin can be extremely difficult to contain. Be extra diligent if you are in the back country. Watch for bad weather and have a safe route out.
