Fall begins with warm weather; smoky skies in Sierra

Fall officially arrives tonight -- but first two days of warm weather.

The National Weather Service is forecasting warm and dry weather early in the week. Temperatures are expected to be in the mid-80s in Sacramento on Monday and Tuesday.

Then, cooler and breezier conditions should move into Northern California. There’s even a chance of rain predicted for later in the week.

Fall arrives at 7:29 p.m. tonight. Before tonight’s September equinox, the weather service is forecasting some pretty hazy conditions for mountain locations such as the Blue Canyon area. A dense smoke advisory has been issued by the NWS for South Lake Tahoe, Truckee and Incline Village.
