Smoke from Canadian wildfires infiltrated American cities this week. While it has made for some spectacular sunsets, the air quality has gone downhill. Many cities along the northern tier of the U.S. are reporting unhealthy levels of pollutants. https://twitter.com/mpca_aqi/status/1134505169318752256 Two dozen fires burning in the Canadian Province of Alberta have forced thousands to evacuate from their homes. In fact, the majority of the smoke originates from massive fires out of northern Alberta, a western province in Canada. https://twitter.com/NWSHastings/status/1134482057260703745 Recently, a blocking pattern that has sparked a string of severe weather across the United States has led to a prolonged stretch of dry weather for western Canada. A significant pattern change over North America is anticipated into next week and this will lead to a cooler, wetter pattern for western Canada. This will help diminish the ongoing fires over the province and improve the air quality across the board.
