Minimal impacts with hazy conditions

Yesterday’s 24hr AQI data indicated good to moderate air quality across the state. Air quality forecasts for today are in the good category. 

Once again, we're lucky to not have any regional smoke for most of the day. Smoke from California fires will track north over the Pacific Ocean before turning east late this evening and into tomorrow. Smoke impacts are expected to be limited to areas near any local fires. In addition, there may be limited surface smoke in the Lower Treasure Valley this afternoon that will rise up during the afternoon and settle down in the evening. Generally hazy conditions with smoke aloft should be expected across the southwest and portions of central Idaho.

Another clear day

Once again, the skies are looking clear for today. Air quality is forecast to be in the good category across the state today. 

Regional smoke is expected to stay out of Idaho while there may be some local smoke impacts from Idaho fires. These conditions look to persist through at least tomorrow morning. After that, upper level smoke is expected to enter central Idaho tomorrow morning but it looks to stay aloft. Beginning around 6pm MDT tomorrow, this lofted smoke will settle at the surface starting in Idaho County and tracking south to the fringes of the Snake River Plain.

HRRR-Smoke 06Z Vertically Integrated Smoke: Smoke will track north along the Pacific Coast before curling into central Idaho tomorrow morning.  This smoke is not expected to reach the surface and should stay aloft through the day tomorrow.

Clear day ahead

 Air quality is forecast to be good to moderate across the state today.

The air should be clear today aside from areas near local fires. These conditions will continue through at least tomorrow. Late Tuesday night and early Wednesday morning could bring a change in wind direction and also bring smoke towards Idaho.

Weekend looking pretty good!

Light smoke from California is expected to arrive in southwest Idaho by late morning and quickly spread across most of south Idaho this afternoon. Impacts should be short lived as a cold front coming through this evening will clear the air from west to east through the night. 

By Saturday morning, all areas should be free of smoke impacts with the exception of potential impacts near local fires, particularly the Woodhead fire in Washington County. Northwest flow will keep the state clear of regional smoke through the rest of the weekend.

Clearing out tonight and tomorrow morning

Air quality is forecast to be in the good to moderate category across the state today.

Smoke from north Idaho has cleared but south Idaho can expect more smoke today coming in from California. This smoke will traverse the Snake River Plain throughout the day and leaves the state to the east last this evening and early tomorrow morning.

Conditions are expected to be clear across the state tomorrow!

Waves of smoke throughout the day

Air quality was in the good to moderate range yesterday and today's 24 hour AQI is forecast to be good to moderate.

Pulses of smoke from California will continue to move into the state today interspersed with periods of clearing. This smoke is expected to continue to track north into the Central Idaho Mountains throughout the afternoon with a stronger secondary surge of smoke expected to reach the Idaho-Nevada border by around 2am tomorrow and reach the Snake River Plain by 7am tomorrow morning. 

Continued smoke impacts are expected across central Idaho today with increased impacts tonight around 10pm across that area, up to as far north as Clearwater County.  Beginning by 2am tomorrow morning, a strong frontal passage will clear smoke from northern and central Idaho through at least tomorrow.  Higher smoke impacts will be likely in the vicinity of local fires as well as in the morning and evening hours.

Not too shabby out there

Air quality was good to moderate yesterday across the state and is forecast to be in the same range today. The smoke from California that moved into southern Idaho yesterday mostly remained aloft and little air quality degradation was noted at the surface. Waves of light to moderate smoke from California and Oregon look to continue moving into the state today. Again, how much of this smoke remains aloft and how much mixes down to the surface is an open question but at least widespread haze should be expected. Higher smoke impacts will be likely in the vicinity of local fires.

Smoke should be arriving later today

We hope everyone was able to enjoy some blue skies and clear air this weekend! Unfortunately, that will come to an end today as southwest flow returns. Smoke from California wildfires should begin arriving in southern Idaho later this morning and will spread northeastward across all but the Panhandle by this evening. It is still unclear how much of this smoke will actually mix down to the surface but some air quality degradation is expected across most of the state overnight into Tuesday morning as the smoke settles in after sunset. Widespread haze with smoke aloft is likely this afternoon.

Heavier impacts could occur in the vicinity of numerous wildfires burning in Idaho, particularly the Woodhead fire in Washington County. The only area expected to avoid smoke impacts today into tonight will be the Panhandle.

 Air Quality Advisory Remains in Effect for the Nez Perce Reservation

 The Air Quality Advisory issued for the Nez Perce Reservation is extended through Noon Saturday, September 19th, 2020. Wildfire smoke from the Sunnyside Complex and fires in California/Oregon/Washington continue to impact our area. Air quality improvements are expected late Friday night into early Saturday morning; however, the amount of smoke clearing remains uncertain.

 Smoke may move in and out of the area depending on fire and wind activity; some areas may be more impacted than others. No EPA/NPT burn permits will be approved. This Advisory expires Noon Saturday, September 19th, 2020 unless air quality conditions warrant a continuation.  

Air quality is currently in the “Unhealthy” category of the Air Quality Index. To track regional air quality, visit the Idaho Smoke Blog or the AirNow Website. For AQI health-related information, visit: AQI Basics.

Brief relief on Sunday!

Get out your packs and boots! Get ready! Now wait...until Sunday. You'll get one day of relief so use it wisely!

Friday will be a transition day - it will still be smoky but as Saturday comes so will a deep trough from the Pacific. It will push through from southwest to northeast starting Friday night through Saturday morning. This cold front will bring a colder air mass that should scour the much of the smoke from the state. The exception (there's always an exception isn't there?) will be in proximity to the numerous wildfires currently burning across Idaho. Generally clear air should remain for Sunday before smoke begins to stream in again on Monday from the fires in California. Air quality will likely degrade on Monday, particularly in the southern half of the state.

To sum it up: smoky Friday, clearing Saturday, nice Sunday, smoky Monday.

Relief may be on the horizon tomorrow

Idaho continues to be underneath a shroud of wildfire smoke from regional and local fire this morning. Once again, air quality is forecast to be in the moderate to very unhealthy range across Idaho - increasing in concentration gradient as you go north. 

Waves of smoke are moving across the state from the southwest to west and will continue to do so through the day. North Idaho saw some improvement yesterday and overnight but this trend looks unlikely to continue today. However, air quality may improve some this afternoon elsewhere as surface winds and mixing crease in the afternoon.

Some relief is possible beginning tomorrow evening with the arrival of the Pacific cold front.

Smoky through Friday

 Air quality across the state is currently forecast to be in the moderate to very unhealthy range - increasing in concentration as you move north. There still isn't much change in the weather pattern and we will continue to have sunny/hazy skies and light winds across the state through Thursday. Smoke continues to stream in from Oregon, Washington and California.

There may be some improvement this afternoon as mixing increases but overall little change is expected from yesterday. Southeast Idaho may even see some degradation in air quality as some of the smoke shifts east - though it may remain aloft through the day. 

Significant clearing is still not expected until at least Friday and even then, the clearing may be brief.

Air Pollution Forecast and Caution Extended for Eastern Idaho

The Idaho Department of Environmental Quality (DEQ) Idaho Falls Regional Office has extended an Air Pollution Forecast and Caution for residents of Bonneville, Butte, Clark, Custer, Fremont, Jefferson, Lemhi, Madison and Teton counties. The next update is expected Friday, September 18th at 2:00 p.m.



More of the same today with minimal improvement

Overall, everything is looking about the same as it did yesterday. Air quality ranges from good in the southeast to very unhealthy in the north. There has been very little change in the weather pattern since yesterday and no significant changes are expected until Friday. 

North Idaho will continue to see thick smoke moving in from the Cascades but could see some gradual improvement today as a cold front approaches from the northeast which may allow some clearer air to mix in with the surface smoke. Southwest Idaho will see lesser, though still significant, impacts from smoke moving in from California. Southeast Idaho will again avoid all but the lightest impacts today. North Idaho should see some more gradual improvement
