High pressure will stay camped out to our west and will stick around into next week. High-pressure systems are usually associated with sunny skies and calm conditions. Today into next week, the state will have an ample amount of sunshine, a slight breeze at times, and the highs will stay in the 40s and 50; the valleys in western Montana highs will struggle to reach the 40s. As high-pressure camps out and strengthen, inversions will keep cold air trapped beneath warm air, creating a pocket of stagnant air. Another thing to keep in mind during an inversion stagnant air mixed with pollutants can get trapped under these layers and will allow for the air quality to deteriorate. All morning Seeley Lake's air quality stayed at an unhealthy rate, which means anyone who suffers from respiratory disease, such as asthma, should avoid prolonged exertion. Low lying clouds/fog will also develop during an inversion.
Looking ahead into next week, high-pressure system will start to break down, and an area of low pressure will move in. Tuesday night will be the next chance for precipitation.
Have a great day,
