Another return of monsoonal moisture in the Lake Tahoe area by mid-week

SOUTH LAKE TAHOE, Calif. - Another surge of monsoon moisture will bring back thunderstorms to the region this week, with the best chances being Tuesday, Wednesday, and Thursday.

Each day Tuesday through Thursday, most areas in the region will have a 20 to 40 percent chance of seeing a storm, 10 to 30 percent in South Lake Tahoe. Storms are most likely in the afternoons and evenings, but overnight showers and storms cannot be ruled out.

Impacts will range from lightning, new fire starts, and strong outflow winds with blowing dust, to periods of heavy rainfall and flash flooding. The National Weather Service (NWS) in Reno said it is too soon to project which hazards will be dominant so be prepared for any of these scenarios.
