Tahoe Weather Geek
Monday March 17
Breezy conditions and cooler temperatures today and Tuesday in the Tahoe Basin as one final cold front of winter — another dry one — makes its way across the region. Any precipitation from this system will remain far north of Tahoe near the Oregon border.
The same will be true for the remainder of the work week and, it appears, well into the first week of spring. The exception might be a weak system expected to pass through Northern California around Friday, but that one is not expected to do much, if anything, to reduce our precipitation deficit.
Next weekend looks dry and warm again, with temperatures above normal for the first week of spring.
Monday March 10 2014
Rain has turned to snow above about 6500 feet in the Tahoe region this morning as a cold front at the tail end of a storm system pushes through the Sierra. Snow showers should last through the morning and perhaps into the afternoon but accumulations below 7000 feet are expected to be light. A total of 4 to 6 inches of heavy snow is possible above 7000 feet befoe the storm winds down.
Temperatures will be on the chilly side for a day or two as cold northeast winds move in behind this system.
But a ridge of high pressure is forecast to build by the middle of this week over the western US, bringing on a widespread warming trend. High temperatures in the 50s or even 60 are likely by the end of this week, and there are no additional storm systems on track for Tahoe at least through the 7-day forecast period.
Stay tuned for updates. We will let you know if there’s another dose of winter weather in the mix before the start of spring.

Rain and high elevation snow is likely in the Tahoe Basin later today and tomorrow.
A significant plume of subtropical moisture was moving into Northern California this morning and is expected to slowly make its way south and east toward the Northern Sierra.
Rain with snow above about 8000 feet is likely late today, with several inches possible around Mt. Lassen and about an inch likely further south.
Snow levels should drop overnight as the cold front moves through, with snow possible as low as 6000 feet on Monday. The Sierra passes around Tahoe could see two to four inches of snow by Monday afternoon, with several more inches possible above 8000 feet.
Snow should taper to showers later Monday with clearing likely by Tuesday. Temperatures will dip behind the cold front as brisk winds from the Northeast chill the region for a day or two.
But a ridge of high pressure building over the west is going to bring warmer temperatures and a return to springlike conditons later in the week.
Saturday March 8 7:30 am
A mild and springlike day in Tahoe today — with highs in the 50s — will give way late Sunday to another warm, wet system from the Pacific that promises to bring rain and high elevation snow to the region.
This system could bring several inches of rain to the far Northern Sierra and Southern Cascades, but perhaps only around an inch or less to the Tahoe Basin. Snow levels are forecast to start out above 7000 or even 800 feet Sunday afternoon or evening before falling to close to 6000 feet overnight or Monday morning. If the cold air moves in quickly enough we could still see around 6 inches of snow at the passes with more on the highest peaks around the region.
Snow showers are likely to continue much of Monday before the storm moves east.
Temperatures will be chilly for a day or two after the storm under the influence of cold northeast winds.
But a warming trend later in the week is forecast to bring unseasonably high temperatures to Tahoe by next weekend.
