Mineral King to Mt. Whitney

The Winter Storm Watch issued by NWS Hanford (active through November 17) is the defining factor for this trip. Wednesday and Thursday look clean — sunny, light winds, temps topping out at 45-50°F at lower elevations, but remember that Mineral King sits around 7,800 ft and Whitney Portal approaches 14,000 ft, so actual temps on the high passes will be considerably colder than the forecast lows of 29-31°F suggest. Friday is the wall: 90% precip, snow likely, winds building to 10-15 mph NW. That storm isn't clearing until after the 17th, which is well past your exit date. You need to be off the high terrain or committed to a shelter plan before Friday morning.

Short days are a real logistics constraint. Sunset at 4:50 PM gives you roughly 10.5 hours of usable daylight, and on a route with technical passes like Forester Pass at 13,200 ft, you want to be over the high points by early afternoon anyway — both for weather margin and because November afternoon temperatures drop fast. Plan your camp placement so you're hitting major passes before noon each day. The Wednesday-to-Thursday window is your strongest weather, so front-load your mileage.

The stream crossing data in this briefing is from gauges well outside the Sierra Nevada (Salinas River, Llagas Creek near Gilroy) and doesn't reflect conditions on the Kern River or tributaries along this route. With zero snowpack at all SNOTEL stations and no recent precipitation, Sierra stream flows are almost certainly at late-season low — crossings should be straightforward through Thursday. That changes if the storm front arrives early or if any rain-on-bare-ground runoff occurs Friday. Watch for any early precip signs Thursday evening.

No fires within 50 miles, snowpack is at zero so no avalanche terrain concern on approach, and the weather window Wednesday through Thursday is legitimately good for November Sierra travel. This trip is doable, but it has a hard deadline. If you're not over Forester Pass and descending toward Whitney Portal by Thursday afternoon, you're making decisions in a storm. Have a bailout — Guitar Lake or Wallace Creek camp with a Thursday exit via Whitney Portal are your best options if you need to cut it short.
