Smoke drifting in from several active Colorado wild fires has resulted in a thick haze across parts of southern Colorado. You will see and smell this wild fire smoke through the morning hours, especially during the morning inversion (warm air above us in the atmosphere).
Air quality reports of moderate to unsafe for sensitive groups are in effect from Denver down the I-25 corridor to the southern border.
Instead of one fire in particular, several fires are feeding this smoke across and down the Front Range from Denver into Colorado Springs. To the north, especially south of Denver to the Springs, the main culprits seem to be the Lake Christine, Sugarloaf, and Weston Pass fires. Westerly winds aloft are slowly blowing that plume of smoke into our area.
To the south, the Spring fire is still burning. Even with containment at 91%, smoke still seems to be traveling east into the southern I-25 corridor.
A small change of the wind direction to the southwest up above in the atmosphere, as well as monsoon rains, may provide some relief by Saturday.
