¡Buenos días, my friends
Cup'☕️ 'Joe in hand on a #TakeThePowerBackTuesday, and would you look at that: stars. Actual stars. The Sierra threw a four-day tantrum, buried us in 4ft of #SpringSchmooPOW, and now she's sitting there this morning with a cup of tea and a smile as if nothing happened. Partly cloudy skies, 27º at the Haus, snow on the deck, KirkwoodMtn, 21º. Palisades, 24º. Top of Donner Pass, 22º. Winds variable, SSW 11/15mph. Another bluebird day on-tap regionally, and the conditions read like a choose-your-own-adventure: snows-baller up high, windbuff, chalky early, with the firming/melt cycle doing its daily push-pull from here forward. It's a classic springtime in the Sierra, and she'll start serving all the food groups at once.
For the record, 4ft of new from Friday night through Monday morning. That happened, and now the mountain team is doing what mountains do after a bender: letting it set up, grooming it out, and getting ready for round two.
Here's your forecast:
Tuesday: Sunny. High near 50º. Calm wind becoming SW around 5mph in the afternoon. Bluebird. Go get yours.
Tuesday Night: Partly cloudy. Low 26º. SW around 5mph, going calm. Freeze cycle locks it down. Tomorrow's corduroy is being built tonight.
Wednesday: Mostly sunny through the morning. High near 50º. Light S wind becoming SW 5-10mph in the afternoon. But here's the footnote: we have a #NextWave, a #Disturbance in the force rolling in Wednesday afternoon. Lake Wind Advisory in effect for Tahoe from 11am to 11pm Wednesday, Wind Advisories across the Sierra Front, Surprise Valley, northern Washoe, and inner-basin. Latest guidance shows a 30-70% chance of gusts hitting 45mph or greater in western Nevada. Strong cold front, pre-frontal westerlies ramping through the region. If you're on the water, off the water by midday.
Wednesday Night: This is where the disturbance makes its move. Snow levels start high, 9k?, with rain/snain showers before 8pm. Rain and snain mix between 8pm and 2am as snow levels drop through the pass elevations. After 2am, full transition to snow (heavy/wet) as levels fall below 7,000ft. Mostly cloudy. Low 26º. SW 5-10mph, gusts to 25. Tahoe Basin carries a 40-60% chance of seeing precipitation Wednesday afternoon into Thursday morning, but this is not a major precipitation maker: QPF amounts running zero to around a quarter inch, with only a 20-40% chance for measurable snowfall in the Sierra. She's knocking on the door, not kicking it in.
Thursday: 40% chance of snow showers before 11am, then mostly sunny. High 44º. W wind around 5 becoming N in the afternoon. Little or no new accumulation. The disturbance tips its hat and keeps walking.
Thursday Night: Clear. Low 18º. N wind around 5 becoming E after midnight. Cold, calm, and quiet. Stars again.
Looking ahead: Sunday has another system on the radar, with snow levels potentially dropping into the 5,000-6,000ft range and a 30-50% chance of more meaningful precipitation. Stay tuned. The season is not done writing chapters, and our last resorts are keeping the bull wheel spinning through the 19th. Every day from here is a gift, Tribe. Treat it like one.
The guidance models this morning agree: this midweek system is a glancing blow, not a haymaker. The real story this week is the bluebird window we're sitting in right now. The snow from this weekend is groomed, set up, and waiting. Spring corn cycles will be firing. The coverage is still #LowTide. If you've been waiting for a perfect Tuesday to play hooky, the universe just handed you your excuse.
Now, get outside. Get'cha some…
Stay Thirsty, my friends
