Here is the latest National Wildfire Potential Outlook covering July, August and September: http://www.nifc.gov/nicc/predictive/outlooks/monthly_seasonal_outlook.pdf
So, we are expecting a “normal” fire season in Northwestern Montana, which will begin as early as mid-July and last through the end of September. Normal means that we will have a number of lightning fires, and fires that occur with good position with heavy fuels on active burning days will move significantly. If we get recurring moisture that keeps the live fuels moist it can reduce the severity of fires absent wind events. But we will see those effects diminish as shrubs cure out in September.
