Tahoe Weather Geek
The first cold storm of the season is moving into Tahoe today, just in time for the October. 1 start of the precipitation year.
Some areas are already seeing showers this afternoon, and the rain should intensify later tonight and Thursday morning. The low pressure system currently sitting off the California coast is expected to move inland by midday Thursday and pass into Nevada Thursday night.
Snow levels should remain above 9000 feet for the duration of the storm. Up to about an inch of rain is possible in the Northern Sierra with about half an inch likely south of Tahoe.
Another storm is due late Saturday into Sunday, with cooler temperatures and slightly lower snow levels, still likely around 8000 feet.
Stay tuned for more info.
Tuesday April 7
An early spring storm forecast to sweep through the Sierra today will remind Tahoe residents and visitors of the winter we never had.
Rain is already moving across California’s Central Valley and snow is expected to fall by late morning or midday in the Tahoe Basin.
Snow levels will likely start around 5000 feet and drop to below 4000 feet later in the day. About 6 to 12 inches of snow should fall by Wednesday morning above 5000 feet with higher totals across the Sierra Crest. High temperatures will be in the 20s and 30s this afternoon.
The low pressure system looks to spin into Nevada and Utah by Wednesday morning, with a few isolated showers possible in its wake. A warming trend should bring temperatures back to the 50s by the end of the work week.
Thursday April 2
Unsettled weather is on tap for Tahoe over the next few days as a couple of early spring but winter-like storms move through the Northern Sierra. Snow, with unusually low snow levels for this time of year, will be likely Sunday and again early next week.
This won’t be an April miracle. It’s not a drought buster. But it will definitely be cold and windy and feel a lot like the winter we never had.
Two cold low pressure systems are targeting the region.
The first is due to arrive late Saturday or early Sunday morning. This system will not be tapping into a lot of moisture but cold temperatures will help it wring a maximum amount of snow from a small amount of water. Snow levels are expected to drop to 4000 feet or even lower Sunday morning. Several inches of snow are possible along the Sierra Crest, with the highest amounts north of Interstate 80.
After a brief break, the second system is due Monday through Tuesday night. This system could be a bit more powerful, with up to an inch of water-equivalent precipitation possible. This is likely to translate into around a foot of snow at the higher elevations with 6 inches or more possible above 5000 feet.
Snow should be tapering to showers on Tuesday with clearing beginning on Wednesday.
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.
