A wet holiday weekend will continue today in the Tahoe Basin as a second wave of moisture from a low pressure system moving inland from the Pacific this afternoon brings showers, high elevation snow and a threat of thunderstorms.
We could see up to an inch of rain by nightfall with a few inches of wet slushy snow above 7000 feet.
The storm should be moving east by tonight, with clearing skies likely Monday.
The arly part of the week will be mostly fair and warmer before more wet weather heads our way by Thursday and into next weekend.

A low pressure system that’s been drifting off the California coast for several days will move inland today and Sunday, bringing rain and high elevation snow to the Tahoe Basin.
The rain should start by mid to late afternoon, with snow levels above 8000 feet. Local convection could bring cooler temperatures and lower snow levels to isolated locations.
The rain will likely intensify overnight, with North Tahoe seeing a total of a half to three quarters of an inch of precipitation, and South Tahoe getting a bit less than that.
Snow levels are expected to drop to around 6500 feet on Sunday, so the mountain passes might see an inch or two of wet, slushy snow before nightfall.
Skies should begin clearing on Monday as a high pressure ridge builds along the coast.

Today should be the warmest day of the week as a low pressure system hangs out off the coast of California and the moisture surrounding it begins to stay closer to its core. We could still see a chance of rain showers at the higher elevations but more likely we will see a lull before the low moves onshore tomorrow.
That movement should bring rain and high elevation snow to the Tahoe region Saturday and Sunday.
Rain is likely to begin Saturday afternoon and grow more intense Saturday night and Sunday morning. Snow levels will be very high — above 8000 feet on Saturday, before dropping to below 7000 feet as the front moves through on Sunday. We could see several inches of accumulation at the highest peaks and some slick roads around the mountain passes, which could affect holiday travel on Sunday.
The system should be moving east by Monday morning with skies clearing later that day.
A ridge of high pressure will then build over California, bringing warm temperatures and clear skies for most of the week before another storm system approaches by week’s end.

Wet weather is coming to the Tahoe Basin this weekend.
A low pressure system drifting off the coast of California that has been sending moisture our way will eventually move across Central California. Because this low is unmoored from the jet stream — a cut-off low — its exact timing and trajectory are difficult to predict, but the best thinking at this time looks like it will move inland by Saturday afternoon.
The persistent clouds and high-elevation rain showers that have been with us the past few days will likely turn to more widespread rain and high-elevation snow by Saturday afternoon. Snow levels will be well above 7000 feet Saturday and most of Sunday before falling to around 6000 to 7000 feet Sunday afternoon. We could see 6 to 12 inches of wet snow at the highest peaks, but relatively little accumulation below the mountain passes.
Scattered showers could continue into Monday, but a ridge of high pressure should begin to build by Tuesday at the latest, bringing a renewed warming trend and drier weather to the region.
