Today's Report and Forecast Today's Summary
After wildfire smoke affected western Montana late Friday and into Saturday, cumulative smoke exposures today, on Sunday morning, are still a little high. However, much of the area received rainfall yesterday, which helped to mix out the smoke. More importantly, rain also fell in Idaho, for the first time in two or three months, where wildfires are still active. The rain helped to drastically reduce fire activity yesterday. More rain is expected today, Monday, and Tuesday, to further help firefighters to put out the fires. Winds will increase on Monday and Tuesday, as a strong cold front passes on Tuesday. Air quality will remain GOOD during this period, and it may be such that smoke updates will not be needed past this week. The next possible update will come on Wednesday, when it may be determined that wildfire smoke updates may not be necessary for the rest of the season.
Residents near active fires and under plumes aloft need to remain aware of current conditions and use the visibility guidelines to guide their activity decisions as the situation changes.
