The interaction between wildfires, smoke, and shifting weather patterns is creating uncertainty in forecasts for the coming days.

Understanding the Challenges

Forecasting wildfire smoke behavior is difficult. Even advanced weather models struggle to provide clear predictions when conditions change rapidly. Meteorologists rely on multiple factors, including ground fires, atmospheric winds, and thunderstorms, which can disrupt forecasts.

Some days, these elements can be forecasted accurately. Other days, they become unpredictable, complicating the collective forecast.

Upcoming Weather Shifts

This weekend marks a shift in the persistent weather pattern that has been channeling smoke across Canada and the United States. The exact nature of this shift will add complexity to the forecasts for the next few days.

Challenge in Smoke Prediction

The initial challenge is determining how much smoke wildfires will emit. Smoke concentrations were denser on Tuesday than in previous days due to weather that fueled fast-growing wildfires. These fires burned intensely enough to create their own weather effects, pushing thick smoke into the sky.
