Central Idaho Mountains most affected by smoke

Air quality forecasts for today are in the Good to Moderate Category.

Today, the upper level ridge will remain in place and strengthen, ushering in hot temperatures and dry conditions. Surface winds will be from the northwest to southwest with locally easterly winds in the morning, and over the prairies of central Idaho, northeast winds all day. Surface wind speeds will be from 2-8 mph in southern Idaho and 5-10 mph in northern Idaho today. 

Smoke will continue to affect the Central Idaho Mountains the greatest today with lifting this afternoon, leading to hazy conditions. We will also see smoke over northern Idaho in the form of hazy conditions.  The upper level ridge will keep smoke from advecting large distances, and that smoke looks to drain into the Middle and Lower Snake River Plain this evening into tomorrow. 

Canadian FireSmoke initialized 08Z with 00Z WRF meteorology  (valid 2am 0816 MDT) indicates limited horizontal transport with smoke over central Idaho tracking to the southwest through the evening tonight.
