Smoky southern Idaho

Today’s air quality is forecast to be in the Good to Unhealthy range for most of the state but areas near regional and local fires could experience periods of Very Unhealthy air.

Currently, thick smoke and haze are seen across portions of South Idaho and the Central Mountains. Patchy smoke and haze are seen over East Idaho and the Clearwater Basin. This afternoon, winds will nudge areas of thick smoke from the West Central Mountains into the East Central Mountains. Limited dispersion can be expected across South Idaho, while this area of patchy smoke moves into the Upper Snake River Plain. More clearing will be seen for North Idaho this evening as winds will push the thin smoke and haze southward. Overnight, thick smoke and haze will linger over the Central Mountains with areas of patchy to thick smoke for the Treasure Valley. Easterly winds will increase in the morning and provide intermittent clearing across the Snake River Plain.

Today’s air quality is forecast to be in the Good to Moderate range with brief periods of Unhealthy for Sensitive Groups near regional and local fires.

Patchy smoke and haze are currently seen across portions of the Treasure Valley, the Central Mountains, and North Idaho. Forecast models differ on the predicted concentrations of near surface smoke, as new fires ignited overnight in the region because of thunderstorms. Later this afternoon, westerly winds will nudge patchy smoke and haze into South Idaho and West Central Mountains from the northern California and Oregon fires. Likewise, patchy smoke and haze will drift into the Idaho Panhandle from the Washington and British Columbia fires and linger through the morning. Overnight the patchy smoke and haze over South Idaho will slowly wane while continuing to flow into East Idaho. As the surface temperatures increase tomorrow morning along with winds, limited dispersion will help clear out the remaining patchy smoke and haze.

Smoke and haze to remain over the weekend

Today’s air quality is forecast to be in the Good to Moderate range with brief periods of Unhealthy for Sensitive Group near regional and local fires.

Currently, patchy smoke and haze are seen across portions of the Snake River Plains and the Central Mountains. Light smoke and haze are visible in North and East Idaho. Later this afternoon, the near surface smoke and haze will begin to thicken across most of the state before clearing takes place Saturday morning when surface temperature inversions break. Saturday afternoon, more patchy smoke and haze will move into the Idaho Panhandle from Washington. 

The calm conditions associated with the ridge will allow smoke and haze to remain over the state through the weekend. As temperatures decrease over night, lingering smoke can become trapped under surface temperature inversions and raise local AQI levels until inversions break in the late mornings, offering limited clearing.

EPA Issues Air Quality Advisory on Fort Hall Reservation

(Seattle—Friday, July 26, 2024) The U.S. Environmental Protection Agency (EPA) Region 10, in coordination with the Shoshone Bannock Tribes of the Fort Hall Reservation, has issued an air quality advisory on the Fort Hall Reservation due to the elevated pollution levels caused by regional fires. Weather forecasts indicate poor air quality will continue at least through the weekend into Monday. This advisory is in effect until further notice.

Large fires in Oregon and California will be contributing smoke to Fort Hall.

 

To keep levels of smoke as low as possible indoors, create a clean room. A clean room may be most helpful for people who are at greater risk from the effects of smoke such as people with heart disease or lung disease, older adults, children, and pregnant people. 

 

These sensitive groups should avoid outdoor exercise and minimize exposure to outdoor pollution as much as possible. As pollution levels increase, the EPA recommends that residents restrict activity and use N95 masks.

Patchy to thick smoke will continue to move into most of the state today with limited dispersion. Overnight, patchy smoke begins to drift into the Idaho Panhandle. As winds increase tomorrow afternoon and take a more southerly direction, limited clearing will be seen for South Idaho from the Magic Valley to the east. Smoke will then settle early Sunday morning in those areas that had limited clearing.

The HRRR-NCEP Near Surface Smoke initialized at 6am MDT July 26, 2024 shows smoke and haze across the state. Most of the smoke is coming from fires in East Oregon, western Montana, Central Washington, and northern California while local fires in Idaho are adding to the total smoke seen. 

 

Brief clearing last night but smoke to return today

Air quality today is forecast to be in the Good to Unhealthy for Sensitive Groups range. The Treasure Valley, Clearwater Basn, and the Idaho Panhandle could see brief periods of Unhealthy.

Last night, winds and showers from regional thunderstorms dispersed the thick smoke and haze across the Treasure Valley and the Central Mountains, but light smoke and haze has started to return this morning and continues to impact most of the state with light to patchy smoke and haze for North Idaho.

Afternoon winds will aid in limited dispersion of near surface smoke today for most areas of the state but will also bring smoke from the East Oregon fires into the Central Mountains and Treasure Valley and smoke from the Central Washington fires into the Idaho Panhandle. Light smoke from the northern California fires is flowing into the Owyhee Mountains.

The RAP-NCEP Near Surface Smoke initialized at 8am MDT July 25, 2024 shows light to patchy smoke and haze over portions of the Treasure Valley, the Central Mountains, and North Idaho. Light smoke and haze are seen over the rest of Idaho. Inversions breaking and afternoon winds will aid in the mixing out of some near surface smoke and haze across the state. As winds continue to increase, areas of patchy smoke will move into the Treasure Valley, the Central Mountains, and the Idaho Panhandle this evening raising AQI levels.
