Smoke Outlook
Air quality is
forecast to remain in the Good to Moderate air quality category across the
state, although short term readings will be higher in the Clearwater drainages
and across the Idaho Panhandle. Conditions continue to improve. Currently there are no Air Quality Alerts
issued by DEQ.
Both northern and
southern Idaho will be under the influence of an upper level low pressure
system today and through the weekend.
This system will provide ample opportunity for afternoon thunderstorms
across much of the state. These storms
are expected to be, at best, moderate in nature. This active weather pattern will be the
primary driver through Tuesday of next week before an upper level ridge returns
to northern Idaho and a zonal flow pattern sets up across southern Idaho. Both of these patterns will promote drying
across the state. At this point, there
is little confidence out beyond Tuesday and re-evaluation will be needed as the
new week begins.
The strongest smoke
impacts are occurring across the Idaho Panhandle with light impacts through the
Hells Canyon and Clearwater drainages.
This will continue in the afternoon until favorable convective
conditions develop across north Idaho.
Smoke forecasts
are dependent on predicted fire growth and weather. If conditions change
unexpectedly, impacts could occur. When visibility starts to go below 5
miles, sensitive groups should minimize outdoor activities. Everyone else
should minimize prolonged or physical activity outdoors. Visit the Idaho Smoke Blog for more
information at http://idsmoke.blogspot.com/
Your
eyes are your best tools to determine if it’s safe to be outside. Even if you smell smoke, the air
quality may still be good.
