The warming trend that’s been building all week for the Tahoe Basin will continue in the weekend as temperatures remain above normal through Saturday.
But the heat wave is forecast to break by Sunday as a low pressure system takes an unusual southwest track from the Rockies across Nevada and into Northern California.
This system is expected to park offshore of Northern or Central California by Sunday, then scoop up subtropical moisture from the Pacific and send it in waves over Northern California and Nevada early next week.
The result is likely to be several days when thunderstorms, some possibly heavy, are likely.
At first the best chance for precipitation looks to be north of Tahoe, closer to Lassen. But the moisture could spread over the entire area by Tuesday.
Stay tuned for details.

An area of high pressure over the Pacific is forecast to spread inland today, bringing warmer temperatures to Tahoe for the coming weekend. Afternoon highs are expected to be near 70 degrees at the lake by Saturday and Sunday. A system passing to to the north on Saturday should bring increased winds with breezes of 10 to 15 mph out of the west expected.
The warming rend is expected to pause briefly early next week as a trough of low pressure sags south out of the Pacific Northwest and toward the Rockies. This system is not expected to bring any precipitation to the Tahoe Basin but it should mean slightly cooler temperatures for a day or two.
By the middle of next week the warming trend is forecast to resume with temperatures returning to the high 60s and possibly over 70 degrees.

An area of high pressure building over the west is bringing a warming trend to the Tahoe Basin.
Temperatures will be in the 50s today and Friday and might creep into the 60s by Saturday.
A weak low pressure system moving south through Oregon and Eastern Nevada Sunday night and Monday could bring some gusty winds and slightly lower temperatures to the region. But the pause in the warming trend, if it comes, will be shoirtlived, as the high will dominate at least into the middle of next week.

Chilly north winds will keep the Sierra Crest and Eastern Sierra on the cool side today and tonight as a ridge of high pressure starts to build over Northern California.
A warming trend is forecast to gradually take hold over the next few days, with highs in the Tahoe Basin reaching the 60s by this weekend.
The warm spell is expected to continue into next week as the area of high pressure spreads over the western US.
