Chance of rain to start the week at Lake Tahoe as record-breaking temps bid farewell, for now

SOUTH LAKE TAHOE, Calif. - The heat wave appears to have been broken, or at least put away for the summer, with more seasonal temperatures and weather. Thicker smoke layers from the Mosquito Fire will keep daytime heating in check for some areas as a low-pressure circulation centered over the Pacific Northwest sends a trough into the picture.

This looks to enhance storm production as the trough provides a shear component that will allow storms to become more organized than what has already been in the Sierra, according to the National Weather Service (NWS). Precipitation chances for the Sierra will be 60-80 percent, while Tahoe Basin and Reno-Carson will have around a 50 percent chance of seeing showers and storms on Monday.

Cooler weather is expected for the bulk of next week as a trough develops over the northwestern U.S. A stronger trough is forecast to develop in the eastern Pacific around next weekend. It is too soon to tell if the weekend will be a wet and/or windy one.
