Meteorological Forecast and Air Quality Discussion:
Today, an upper level ridge will build to the west, allowing continued warming and a northwest flow. Watch for weak frontal passages that will increase surface wind speeds and change surface wind directions. The surface wind direction will be from the northwest to southwest at 5-15 mph. Skies will be mostly sunny to sunny. Mixing heights are expected to range from 4,000-7,000 feet AGL over all airsheds. There is evidence for a weak marine push up the Columbia Gorge and impacts look to be confined to the vicinity of the southeast border of the NPT lands. The winds aloft over northern Idaho will be from the southwest to northwest at speeds of 5-15 mph. Ventilation will be POOR in the morning and become GOOD in the afternoon. The inversions will break out between 10am-12noon. Air quality is good to moderate. PM2.5 and ozone concentrations are below program concentration thresholds except for Boundary county where PM2.5 concentrations are above program concentration thresholds.
