Rain, snow possible today

May 16 2013

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.

T-storms ending, dry and warm for the weekend

Thursday May 9 2013

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.

Showers, even some snow, possible today

Monday May 6 2013

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.

Warm through Saturday, then thunderstorms possible

Thursday May 2 2013

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.
