Fire and Aviation Discussion for Libby, Montana

Fire Weather Discussion as of 9:55 p.m. MDT Thursday, July 17, 2025

Dry and hot conditions will continue during the day on Friday but the rainfall from Monday into Tuesday has certainly helped things out for the time being with most areas across Northwest Montana picking up between 0.50 inch to 1.00 inches which was very beneficial. Overnight relative humidity recoveries will be fair to poor in thermal belts on mid slopes, hillsides and across higher elevations while on valley floors good to excellent recoveries can be expected. Winds will remain light until Friday afternoon when they will pick up from the south and southwest in the 10 to 20 mph range. Minimum relative humidity values during peak heating on Friday will be between 20-25% which will help further dry out fine fuels.
