LAKE COUNTY, Calif. — Weather forecasters and air quality officials are predicting a Labor Day weekend with smoky skies and warmer temperatures.

The National Weather Service said temperatures are expected to rise into the 90s over the weekend across much of the county, with the hottest temperatures — near the century mark — in south Lake County.

The forecast also includes a prediction of widespread haze on Saturday and Sunday, with conditions starting to clear on Monday.

The Lake County Air Quality Management District said that stable atmospheric conditions together with light winds are expected to result in smoke levels increasing throughout the county this weekend.

Fires including the Monument, McCash, Dixie and Caldor continue to create regional smoke impacts throughout Lake County and the Western States, the Air Quality Management District reported.

The district said Lake County experienced good to moderate air quality on Friday.

However, the air quality forecast through Sunday will range from “moderate” (Air Quality Index of 51 to 100) to “unhealthy for sensitive groups” (AQI of 101 to 151) with areas at lower elevations expected to experience the most smoke impacts.

Current weather models indicate smoke building during the early morning hours with gradual clearing during the daytime.

Much of the smoke is expected to stay in the Highway 101 corridor on Saturday, while Lake County should experience mostly good to moderate air quality.

The district said to expect fluctuating periods of poorer air quality as the occasional wind gusts push that smoke into our area.

On Sunday, the district said Lake County will see a change with most areas of the county forecast to reach “unhealthy for sensitive groups” throughout the day.

On Monday the district anticipates some clearing of the smoke with air quality expected to reach moderate levels based on the current weather forecast.
