A stagnant high pressure system centered over Quebec has moved a plume of smoke created by western Canada wildfires over the Maritimes.
The tiny particulate matter that comprises the smoke is mostly located high aloft of the region and is thick enough to dim the day. For many in the Maritimes, the sun had a grey-white washed out appearance on Wednesday.

Fortunately, the smoke does not seem to be severely impacting air quality near the surface. The air quality monitoring site does have a few stations in the Maritimes reporting an elevated level of PM2.5 which is the classification of pollutant associated with wildfire smoke.
The plume and haze will be most noticeable in the region Wednesday through Friday. Modelling has the plume and haze dissipating through the weekend.
