Here's a comprehensive look at your weather forecast for the upcoming Friday and weekend. Several regions across the United States face potential weather hazards, so it's essential to stay informed and prepared.

Across the Plains, Mid-Atlantic, and Southeast, there are slight risks of excessive rainfall and severe storms extending through Saturday. Urban and low-lying areas are particularly vulnerable to flash flooding due to the anticipated heavy downpours. Residents in these regions should monitor local weather alerts and take necessary precautions to avoid flooded areas.

Heat Advisories have been issued for the Gulf Coast and Southeast, where high temperatures and humidity will combine to create dangerously high heat index values. It's crucial to stay hydrated, seek air-conditioned environments, and avoid strenuous activities during the hottest parts of the day. Check on vulnerable friends, relatives and neighbors to ensure they are taking proper precautions.

A frontal system is expected to trigger widespread storms as it moves across the country. These storms may bring strong winds, heavy rain, and lightning. Stay indoors during thunderstorms and secure any loose outdoor objects that could be blown away.

Additionally, Canadian wildfire smoke continues to impact air quality in the Upper Midwest and Great Lakes regions. Air Quality Alerts are in effect, advising people with respiratory issues, children and the elderly to limit their time outdoors. Consider wearing a mask if you must be outside, and keep windows closed to minimize indoor air pollution.

Stay tuned to local weather updates and heed any warnings issued by local authorities to ensure your safety during this period of varied weather conditions. With risks ranging from flash flooding to severe storms and heat waves, being prepared is the best way to navigate the weekend.
