A low pressure system moving through the Sierra is bringing cooler temperatures to the Tahoe Basin this morning, with rain and high-elevation snow mostly north of Interstate 80. Precipitation totals are expected to be around a quarter-inch, with higher amounts possible further north in Lassen County. With temperatures 15 to 20 degrees cooler than Wednesday, snow levels are forecast to hover between 7500 and 8500 feet, with some light accumulations possible.

Rain and snow are expected ro decrease tonight as the front moves east but scattered showers will remain possible in the Sierra overnight and even into Friday. There’s a slight chance of thunderstorms around the Tahoe Basin Friday afternoon.

A slow warming trend is forecast to take hold for the weekend, with temperatures climbing back into the high 60s by Sunday afternoon.

An area of high pressure building over the western US is forecast to bring an end to the showers and thunderstorms that have dampened the Tahoe Basin for much of this week.

Scattered thunderstorms, especially in the afternoon, remain possible today and Friday and warming temperatures and residual moisture combine to form a few thunderheads.

But the high pressure will put a lid on the region by Saturday, keeping any clouds from rising into thunderstorms. The air will also be drier.

The warming trend is expected to push temperatures around the lake to around 70 by Friday and the mid 70s over the weekend.

The calm weather should continue into next week, but a low pressure system could move through the Sierra on Wednesday or Thursday.

A low pressure system off the coast of California is sending moisture into the Sierra this morning, bringing showers, thunderstorms and a chance of high elevation snow.

Several inches of snow are possible above 8500 feet today in the Northern Sierra, with some snow possible down to about 7500 feet. Widespread rain showers and afternoon thunderstorms are likely today around the Tahoe Basin as the low scoops up subtropical moisture from the Pacific and shuttles it over the mountains.

This system is expected to push east on Tuesday but moisture wrapping around the backside of the low will make another round of showers possible.

By Wednesday temperatures will begin to warm again, and with the residual moisture will mean a chance of more typical afternoon thunderstorms over the higher terrain.

A warming trend is forecast to push temperatures back above normal again by the weekend.

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.

Stay tuned.

A low pressure system heading into Northern California brought gusty winds to Tahoe today with light snow in the forecast for Monday.

Snow showers are expected to begin tonight, increasing on Monday. A secondary cold front moving in Monday afternoon could bring bands of heavy snow showers to the area, but accumulations will depend on timing and location.

More widespread snow is likely Monday night, with a few inches of accumulation possible throughout the Tahoe Basin, and more on the higher peaks. Showers are forecast to continue into Tuesday morning, with cold temperatures and chilly north winds as the storm moves east.

It’s springtime, which means Tahoe’s weather can go from cold to warm to cold again over the course of a few days. And that’s what is in store for the coming weekend.

Scattered snow flurries are possible today along the Sierra Crest as a weak and fast-moving low pressure system moves through Northern California.

Once that system exits tonight or Friday morning, an area of high pressure is forecast to build over the west, bringing a warming trend for Saturday and Sunday. Temperatures should be near normal for the weekend.

But a colder, stronger system is due to drop out of the north late Sunday, bringing a chance of showers to the region early next week along with colder than normal temperatures. It looks like this system is going to come overland rather than off the Pacific, so precipitation, if we get any, should be light. We’ll see some cold dry north winds in its wake into the middle of next week before things warm up again.

Stay tuned!

Unsettled weather will continue today across far Northern California, but precipitation is forecast to be light to minimal in the Tahoe Basin.

A low pressure system moving across the Sierra Sunday should bring a better chance of rain and snow. Rain is likely to begin late Sunday, with snow levels initially above 6000 feet, then dropping to 5000 feet Monday morning. It looks like this system will leave somewhere between a dusting and a light snowfall on Tahoe’s peaks Monday morning.

Skies are forecast to begin clearing Monday afternoon, with a warming trend likely to begin Tuesday or Wednesday as a ridge of high pressure builds over the west.

Stay tuned for more details.
