Thursday March 19
A late winter cooling-trend is in store for the Tahoe Basin after a warm end to the work week.
Temperatures Friday should be 10 to 15 degrees above normal as an area of high pressure strengthens before breaking down and shifting east.
Gusty winds and increasing cloud cover should move into the region Friday night and Saturday, and temperatures are likely to drop back to normal for mid-March. But precipitation from a low-pressure system moving through the Pacific Northwest is forecast to remain primarily in far Northern California.
Sunday should be mild as well, with winds increasing again and gusts of up to 50 mph possible ahead of another system.
The second storm is expected to reach Northern California by Monday, with the heaviest impacts north of Interstate 80. There is a good chance, however, that some rain and snow will reach the Tahoe Basin. Snow levels would start around 7000 feet before dropping to below 6000 feet as the cold front moves through on Monday. Several inches of snow are possible at the higher elevations around the region.
Stay tuned for more details.
Thursday March 12
A low pressure system that brought some drizzle and a few snow flurries to the Tahoe Basin Wednesday has moved east, and temperatures should be warming as we head into the weekend.
An area of high pressure will briefly rebuild over the west, bringing temperatures back into the high 50s or low 60s by Friday and Saturday.
Another low pressure system will push into the Pacific Northwest late Saturday and Sunday, bringing clouds and slightly cooler temperatures to Tahoe. But as of now it appears that any precipitation from this system will remain north of Tahoe.
Wednesday March 11
A weakening low pressure system moving into Northern California this morning is expected to bring light rain and high elevation snow to the Tahoe region today.
The system is breaking apart as it moves onshore, and that and relatively warm temperatures will limit its potential as a snow producer.
Snow levels were above 7000 feet this morning and are not likely to get much lower during the day. We might see some snow down to 6500 feet, but only briefly. A few inches of snow above 7500 feet is about the best we can hope for from this storm.
Showers are possible through the day and into tonight, with skies beginning to clear tonight and Thursday.
High pressure will rebuild toward the end of the week, bringing a return to unseasonably warm temperatures, but temperatures will likely cool again over the weekend as another low pushes clouds into Northern California.
Monday March 9
After two more days of balmy, spring-like weather, a brief return to more wintery weather is in store for Tahoe this week.
A low pressure system forecast to move into California and Nevada Tuesday afternoon should bring light rain and snow to the Tahoe region by Tuesday night or Wednesday.
Snow levels will be around 6500 feet initially because of the dry air in place as the system moves in. But warmer air associated with the trough will likely push snow levels to above 7000 feet by midday Wednesday. A second wave later Wednesday could bring snow levels back down as the cold front moves through. But total accumulations above 7000 feet are expected to be light, probably in the 3 to 6 inch range.
Skies should be clearing by Thursday as the high pressure rebuilds, and temperatures will return to unseasonably warm levels by Friday,
Another low pressure system on track to sweep through Oregon and Northern California Saturday or Sunday will likely bring clouds to the region but very little, if any, precipitation.
