Fire fumes persistently cover the Midwest, while flood threats menace the Southward region.
Severe thunderstorms are set to hit the Plains region, stretching from the Texas Panhandle to western Nebraska, on Saturday evening. Meanwhile, wildfire smoke from Canada has been affecting parts of the Midwest, leading to air quality alerts in several cities including Minneapolis, Chicago, Detroit, and Des Moines, Iowa.
The Air Quality Index (AQI) is a standardized numerical scale used by government agencies worldwide to measure and communicate air pollution levels to the public. It ranges from 0 to 500, with higher numbers indicating increased levels of pollution and health concern. The AQI helps people understand the risks associated with poor air quality, with categories ranging from "Good" to "Hazardous".
Exposure to wildfire smoke can irritate the respiratory system, reduce lung function, worsen asthma and other lung diseases, and increase the risk of cardiovascular problems. It poses greater risks to sensitive groups such as children, the elderly, and people with pre-existing respiratory conditions. Air quality alerts advise people to limit their exposure during poor air quality events caused by wildfire smoke.
Conditions in much of the Midwest are expected to improve on Sunday. However, strong, slow-moving thunderstorms could drop rain at 1 to 2 inches per hour in these areas, posing a risk of flash flooding. Strong wind gusts, large hail, and flash flooding are also possible in the affected regions.
In the West, the warm, dry, and windy weather is creating dangerous fire conditions. In eastern Oregon and southern Idaho, dry lightning during isolated thunderstorms could potentially start new fires. An extreme heat warning is in effect for portions of Arizona, including the cities of Phoenix and Tucson, where temperatures could top 110 degrees over the next few days. Scattered showers and thunderstorms are forecast for Saturday afternoon in the mentioned states.
In northern Minnesota, northern Wisconsin, and the Upper Peninsula of Michigan, air quality might be unhealthy for everyone at times. No new facts related to wildfire smoke, air quality, or the Midwest were mentioned in the latest updates.

- The AQI, a tool for measuring and communicating air pollution levels, may reach high numbers in northern Minnesota, northern Wisconsin, and the Upper Peninsula of Michigan due to increased levels of wildfire smoke, posing health concerns for everyone.
- Severe thunderstorms in the Plains region could have harmful impacts on businesses and the environment, as heavy rain and flash flooding could cause property damage and infrastructure disruption.
- In the context of climate change, the increased frequency and intensity of wildfires can contribute to poor air quality, exacerbating health issues and damaging ecosystems, particularly in regions where environmental science studies have identified wildfire smoke as a growing concern.
