This week a strong SW flow aloft has produced hot and mostly dry weather with abundant wildfire smoke lifting into Montana from large out of control fires in northern California. This pattern should be breaking down as a cold front passes through the state into Friday and an upper level Low develops over the region this weekend producing cooler temperatures. A north to NW flow is likely this weekend and we are hopeful this will bring improving air quality for several days.
