Tahoe Weather Geek
Thursday Feb. 20
A mild springlike weekend is ahead of the Tahoe Basin, extending into next week before we are likely to see a change to a wetter weather pattern.
Cool and breezy days are expected to give way this weekend to a warming trend, with temperatures 5 to 10 degrees above normal this weekend.
That trend should continue through Tuesday before another stream of subtropical moisture takes aim at the Sierra.
The first in what could be a series of storm system is expected to arrive by Wednesday. The warm moisture tap will mean valley rain and high-elevation snow, but it’s too early to tell just how high the snow levels will go.
The exact track of the moisture plume is also in question, with some suggestion that the bulls-eye might be a little south of Tahoe.
But the odds look good that we will be getting some precip, either rain or snow or both, next week.
Stay tuned for details.

The days ahead look to be cool and a bit breezy for the Tahoe Basin as a couple of storm systems pass to our north.
The first will move through Tuesday afternoon and Wednesday, and it still has the potential to bring a few scattered snow showers to the region on Wednesday. But even north of Tahoe snow accumulations will be light so we don’t expect more than a dusting, if that, from this system.
The second storm will move through Oregon on Thursday and Tahoe is not likely to see any precipitation from that system.
At that point an area of high pressure will build over the west and is forecast to bring sunny and warmer days to the Sierra through the weekend.
A low pressure system out of the Gulf of Alaska will try to push through that ridge early next week, but it’s too soon to tell whether that storm will make it to Tahoe.

What once promised to be a good week of snow for Tahoe has turned into another disappointment as the jet stream has shifted north and looks to remain there for a while.
It now looks as if the few inches of snow we got Sunday morning will be it for this week, and possibly longer.
Another storm due Tuesday night into Wednesday is going to only brush past Tahoe while dropping a few inches on the Northern Sierra and Southern Cascades. Thursday’s storm will be even further to the north.
After that it appears an area of high pressure will build over the west and we will be in for a trend of warmer, drier weather at least into the weekend…
Sunday Feb. 16
A modest storm that brought 1 to 3 inches of snow to the Tahoe Basin overnight is moving east this morning. Scattered snow showers could still leave another two to three inches in favored locations around the Basin before skies clear for good. Windy conditions are likely to continue for most of the day in the storm’s wake.
Another system is still due for Tuesday night and Wednesday but its track has been shifting to the north, meaning most of the precipitation it brings will fall north of Interstate 80. It will be colder, with snow levels down to 4000 feet or so in the Northern Sierra, but with very little moisture in the system by the time it reaches Tahoe we are not likely to see more than a dusting or light accumulations at best.
A third system in the forecast for Thursday now looks to stay entirely north of the Tahoe Basin.
