Keeping an Eye on Eastern Sierra Weather

Those of us spending time in the eastern Sierra this time of year as we chase aspen color (and other subjects) need to pay a bit more careful attention to the changing weather, for photographic reasons and for safety reasons! October is a transitional season in the Sierra, and it can be warm and sunny one day and winter-like and snowy on the next.

Right now there are some question marks in the forecast for the upcoming weekend. I think we are still a bit too far away to get a truly precise forecast, but it does seem likely that the eastern Sierra will feel some effects from a passing weather system by late Saturday or on Sunday.

Some resources for those tracking the weather include:

  • The MammothWeather.com Dweeb Report. This is a private site that is really useful, especially if you learn to read between the lines a bit. To paraphrase (and read between those lines…) it is getting very cold in the eastern Sierra right now, will warm a bit later this week, and then “something” is passing through during the weekend.
  • For slightly geekier (as opposed to dweebier?) weather trackers, the California Forecast Discussion page at the NWS often gives some good hints about how the weather may develop. Currently the sum of the reports here suggests that a) it is going to get colder this weekend, b) a front is going to pass through, c) there is some chance of light snow in the eastern Sierra starting Saturday night, and d) there could be some windy conditions.
  • The NWS Sierra Nevada from Yosemite to Kings Canyon 7-Day Forecast covers a good chunk of the higher portion of the range in short form. Current forecast suggests cloudiness from Saturday evening through Sunday with some chance of precip.

What does it all mean to aspen hunters? A few thoughts cross my mind:

  • If you want reliable sun light in the very early morning hours this weekend, Saturday will be your day. Get up early and be in place before the sun rises.
  • There is some potential for interesting cloud formations and effects as the front approaches (if we get lucky, perhaps close to sunset on Saturday?) and then clears (later in the day on Sunday?).
  • There is a good chance that you’ll be shooting in at least some cloudy conditions. This can be a good thing! Photographing the aspens up close in cloud-diffused light can provide some wonderful saturated colors, though you’ll probably want to do some color adjustments in post. (The light will tend to be a bit blue.)
  • Think of light snow as a positive thing for photographs. There are tons of aspen photographs – but not nearly so many that combine the colorful leaves with a fresh dusting of snow.
  • Dress warmly. If you plan to camp be prepared for wet and cold, and probably give yourself a bit more time to get set up and so forth. Consider camping at a lower elevation if you aren’t prepared for the cold. Think about how you’ll manage your gear as you continue to shoot in cold and damp.
  • Watch out for difficult driving conditions. While a dusting of snow is not usually a major problem, falling snow and dark conditions can make things more difficult – and while you may not find this challenging, keep in mind that quite a few other drivers may not be as secure about this as you are. Also, even a little snow can temporarily close some Sierra passes – the NPS is notorious for closing down Tioga Pass for tiny bits of snow.
  • Wind may be an issue – in several ways. It is not uncommon for a front with strong winds to suddenly bring down some of the most colorful leaves. If you have a higher elevation grove in mind, go Saturday! The wind can also compound the problem of light diminished by clouds – the leaves may be moving a lot. Look for more sheltered areas, wait for a pause in the wind, increase ISO and use a faster shutter speed… or embrace the blur and make it part of your shots. And don’t forget that wind increases the effect of the cold.

Early morning shopping for produce at the Big Star Grocery Co. in Chinatown, San Francisco, California.

In the past I’ve mostly walked past these markets in San Francisco’s Chinatown at more typical tourist times of the day, so I had missed the activity of the early morning hours when the markets are both opening and taking shipments of produce, dropped off on the sidewalks by large delivery trucks and then moved inside manually.

Aspen Grove, Morning, Lee Vining Canyon

Early morning backlight filters through the green leaves of spring aspen trees to fall on meadow grasses in Lee Vining Canyou, California.

My posting sequence has been a bit confusing lately, I’ll have to admit – I’ve gone back and forth among photographs from Seattle, the eastern Sierra, Yosemite Valley, and more. Now I’m going back to the early June Yosemite photographs to post a few that I did not get to right away. This is one in that group. This is another part of the same small aspen grove in Lee Vining that I photographed in early June when the new meadow grasses were just coming up and the trees still retained some of the new growth color. I had stopped to photograph this grove in shadowed light, looking for the soft diffused effect that this creates. I had just about finished shooting this grove when the sun began to rise above the canyon walls and the first direct light filtered among the trees.

Half Dome and El Capitan, Morning Light

Half Dome and El Capitan, Morning Light

The first view of Half Dome and El Capitan upon arriving at Yosemite Valley in the early morning.

Let’s think of this as a work in progress…

Almost every time I enter Yosemite Valley via the northern highway 120 route I stop at this turnout not far below the turnoff to Foresta, where the first view of Half Dome and El Capitan suddenly looms ahead. I am so familiar with this road that I know exactly when this view will appear, but it must be stunning for a first-time visitor to round this ridge and see these icons looming ahead. I pull out, park the car, fit the long lens, and see what the conditions will produce on this particular day.

I have a vision for a photograph that I’ll probably get some day from this spot, but it will take a perfect combination of light (type, angle, intensity) and atmosphere (some haze but some clarity in the scene as well) and conditions (a bit of snow somewhere, perhaps like that on the summit of Half Dome in this photo). I have a feeling that the day on which it happens will not necessarily be an otherwise stunning day – but the conditions for this shot will be right.

In the meantime this version and a companion in landscape orientation that I shot in early May will have to do. Besides the obvious iconic stuff (Half Dome in the far center and the face of El Capitan looming on the left) there are some interesting visual coincidences in this scene. Notice that the curve of the upper right ridge of Half Dome is mirrored in the curve of the foreground ridge in front of El Capitan. The concave curve on the very upper left side of Half Dome (close to the cliff next to the “cable route”) is mirrored by the dip in the foreground trees. The descending angle of the middle-distance ridge on the right side extends into the downward slanting crown of the trees at lower left.
