The warmest temperatures of the summer are expected this weekend through Monday, with highs getting into the upper 80s and 90s with up to 107 degrees in the lower valleys of north-central Idaho and Lemhi County. Drink plenty of water, wear light clothing, take frequent breaks, avoid strenuous activity during the afternoon hours and do not leave children or pets in vehicles.
Hot, dry, and windy conditions will create elevated fire weather concerns across Western Montana and North-Central Idaho starting late this week, through the weekend, and persisting into early next week. These conditions will be locally maximized across Southwest Montana, where higher wind speeds and lower humidity will heighten the potential for rapid fire spread, especially in dry grasses and lighter fuels. Because the majority of wildfires are human-caused, residents and visitors are urged to exercise caution with any outdoor activities that could generate a spark. Check local burn bans before lighting campfires, secure all vehicle tow chains to prevent dragging, and avoid operating equipment or parking vehicles over dry brush. Monitor local forecasts and public land agencies for further guidance.
