Forecasters are eyeing the Nov 29/30 timeframe. The ensemble clusters favor a "Drier/Inside Slider" solution rather than a wet atmospheric river, but it will bring colder temps and wind back to the region.

#HippieHaus | Lake Tahoe Forecast
Lon: 38.880336. Lat: -120.022771 Elev: 6,380
Date: November 23, 2025
¡Buenos días, my friends, Cup'O'Joe in hand, welcome to #SoulfulSunday… #StokeLevelSolid at 11.1 here at the #HippieHaus.
It is 05:22 AM, under a canopy of stars. It is crisp and quiet—a stark contrast to the howling Mono winds of yesterday. The thermometer reads 21º here at the Haus, matching South Lake Airport (KTVL), while Truckee (KTRK) sits at 27º under a blanket of valley fog. We are locked in a High Pressure Holding Pattern, which means cold nights, sunny days, and strong temperature inversions.
Mtn Teams have been pulling all-nighters in this "Snowmaking Power Zone," maximizing the cold air trapped in the basin. Today is a day to enjoy the stillness, the piste, and the clarity.
Looking forward to the next 3–7 days:
Potential Rain and Snow Outlook: The pattern is Dry and Stable through Thanksgiving Day. 0% chance of precipitation.
Long Range Intel: We are tracking a pattern breakdown for the weekend AFTER Thanksgiving (Nov 29/30).
Signal: Ensembles (GFS/ECMWF) are pointing toward a "Colder Trough" or potentially an "Inside Slider" dropping in from the north.
Impact: This would bring a return of gusty winds, much colder air, and a chance of snow showers, but confidence on moisture content is low. It looks more "cold & windy" than "big dump" right now.
Snow Levels: N/A
Temperatures: Inversion Season is here. Expect valley cold pools in the morning (teens/20s) while the ridges warm up faster. Highs at lake level will push 53°, while mid-mountain temps may actually feel warmer in the sun.
Winds / Wind Conditions: Calm. The screaming ridge winds have shut off. Winds today will be light and variable (Northwest 5-10 mph). Note: Winds at FL100 (10,000 ft) will pick up to 30 kts later today, creating potential turbulence east of the Sierra crest.
Road Conditions: ALL CLEAR. No chain controls. However, Dense Fog & Black Ice are the primary hazards this morning in the Truckee/Martis Valley and the Solano County stretches of I-80. Watch for sudden visibility drops.
Weather Advisories | Winter Storm Watches | Wind Advisories:
Lake Tahoe Basin (CAZ072): None.
Eastern Sierra / Mono County (CAZ073): None.
West Slope Sierra / Kirkwood (Alpine Co.): None.
Forecasted Temperatures (Today's High / Tonight's Low):
#HippieHaus (SLT / 6,380'): 53° / 24°
Kirkwood (Base / 7,800'): 46° / 20°
Truckee (North Shore / 5,800'): 50° / 22°
Mammoth Mtn (Base / 8,900'): 33° / 21°
Timing of wind direction/wind speeds: Surface winds are calm/variable this morning, shifting Northwest 5-10 mph by afternoon. Ridge winds (10,000 ft+) will increase late this afternoon (West 20-30 mph), but surface impacts will remain minimal.
Seven(7) Day forecast (Lake Level Highs/Lows):
Today (Sun): 53° / 24° (Sunny, Inversions)
Monday: 54° / 25° (Sunny)
Tuesday: 55° / 26° (Sunny)
Wednesday: 56° / 27° (Sunny)
Thursday (Thanksgiving): 53° / 28° (Sunny)
Friday: 50° / 28° (Clouds Increasing)
Saturday: (Nov 29): 46° / 26° (Cooling, Trough Arrival?)
Changes from Yesterday
Winds: The major change. The Mono Winds (60+ mph) have ceased. We are back to light/variable flows.
Visibility: Freezing Fog (FZFG) has developed in the Truckee/Martis Valley corridor (KTRK) and pockets of the Sacramento Valley, replacing yesterday's crystal-clear start.
Temps: Warming trend aloft (Inversion). Ridges are recovering from the wind chill.
Sierra Avalanche Centers: #KnowBeforeYouGO
Sierra Avalanche Center (Tahoe / Carson Pass):
Status: LOW (Level 1).
Hazard: #SnowSharks (Early Season Obstacles).
Discussion: Shallow snowpack. Recreating is limited to high elevations (8,500'+). Watch for rocks/stumps.
Eastern Sierra Avalanche Center (Mammoth Zone):
Status: LOW (Level 1).
Hazard: Obstacles & Loose Wet Snow.
Discussion: With the sun and warming temps today, surface snow on steep sunny slopes may loosen.
Marina/Lake Guidance Forecast for Lake Tahoe Today:
TODAY... Sunny. Light winds becoming Northwest 5 mph. Highs near 53º.
TONIGHT... Clear. Lows 24 to 28.
MONDAY... Sunny. Highs near 54.
Aviation Forecast: KTRK (Truckee): LIFR/IFR Conditions. Freezing Fog (FZFG) is present this morning between 09Z-19Z (1 AM - 11 AM PST). Expect vertical visibility (VV) to be obscured and horizontal visibility < 1/4 mile at times. Conditions will improve to VFR after 18Z (10 AM).
KTVL (South Lake Tahoe): VFR Prevailing. Mostly clear, but a 20% chance of patchy shallow fog near the runway at sunrise. Winds light and variable.
Turbulence: Moderate turbulence and Low-Level Wind Shear (LLWS) possible along the Sierra Crest and east slopes this afternoon as FL100 winds increase to 30 kts.
Area Forecast Discussions (AFDs) Summaries
For #HippieHaus & Mammoth (NWS Reno): Current Pattern: High-Pressure Ridge overhead. The main story is Valley Inversions (cold air trapped in valleys, warm air aloft) and Freezing Fog in Truckee/Sierra Valley.
Outlook: Dry through Thanksgiving.
Long Range: Forecasters are eyeing the Nov 29/30 timeframe. The ensemble clusters favor a "Drier/Inside Slider" solution rather than a wet atmospheric river, but it will bring colder temps and wind back to the region.
For Carson Pass / KirkwoodMtn Zone (NWS Sacramento): Valley Focus: The main hazard is Dense Fog in the Central Valley/Delta/Solano areas (impacting the drive up I-80/US-50 from the Bay).
Mountain Focus: Clear, dry, and seasonable above the fog layer.
Summary: On this #SoulfulSunday, we wake up to silence and stars. The winds have died, the "Snowmaking Power Zone" is active, and the #StokeLevel is high. Today is about enjoying the clarity—unless you are in Truckee, where the Freezing Fog is thick this morning. Roads are ALL CLEAR (no chains!), but keep your head on a swivel for fog banks on I-80 and around Martis Valley. The travel window for Thanksgiving is wide open. Enjoy the calm, knowing that #MaNatural is likely taking a break until next weekend (Nov 29).
