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.

Last Light, Tuolumne River

Last Light, Tuolumne River

Last Light, Tuolumne River. Yosemite National Park, California. July 10, 2009. © Copyright G Dan Mitchell – all rights reserved.

The last light touches the top of Lembert Dome and the peaks of the Sierra Crest beyond and the light from lenticular clouds is reflected off the surface of the Tuolumne River, Yosemite National Park, California.

If you don’t like sunsets… you may want to check back in a few days – this is the second of what will be a sequence of at least four photographs taken on one amazing evening in Tuolumne Meadows in the Yosemite high country of the Sierra Nevada. I posted one from the series yesterday, so I won’t repeat the entire story, but here is a bit of background information.

There is a particular set of Sierra Nevada weather conditions that I’ve experienced only a few times in its perfect state – but when it happens the sky does absolutely astonishing and magical things. There is at least one photograph in this series that may make you think that I invented the colors in post, but I assure you I did not.

Sometimes in the afternoon a stable wind pattern sets up over the peaks on the Sierra crest. The clouds, in this case the curving lenticular clouds seem to just park over the ridge. If this continues, late in the day the number, height, and size of these clouds can increase dramatically. But, as spectacular as this may be, it isn’t quite enough for the conditions I experience this past week. For this to happen, some broken high clouds should extend to the west of the range – clouds to create color when lit by the last light of the setting sun, but broken so that the light can project east onto the lenticular clouds over the crest.

On this evening I saw all of the pieces falling into place and thought that maybe, just maybe, it might happen. With this in mind I was in Tuolumne Meadow nearly two full hours before the actual sunset. I spent the first twenty or thirty minutes scouting out my location – I needed to know exactly where I would shoot from since I didn’t want to be caught looking for a composition when/if this light arrived. With a composition scoped out I spent perhaps 30-45 minutes wandering around nearby shooting various subjects as the evening wore on. An hour before sunset I was back at “the spot” – covered in mosquito repellant! – and watching and waiting.

I won’t tell the whole story here – but this photo was made at just about the time it became apparent that the “magic light” was not simply possible but actually quite likely.

Dust Storm Near Tucki Mountain

Dust Storm, Death Valley

Dust Storm Near Tucki Mountain. Death Valley National Park, California. April 3, 2009. © Copyright G Dan Mitchell – all rights reserved.

A few people asked me if I got any photographs of the dust storm I experienced on the final day of my spring Death Valley trip. Yes, I did get a few – though photography in a raging dust storm is no easy thing. (I did not make any photographs once I was inside the actual storm – I just wanted to get the heck out of there!) Here the photograph shows the last bit of clear sky as I was about to enter the cloud across Death Valley from Tucki Mountain, which rises above Stovepipe Wells.

Black and white photograph of bicycle wheels in heavy rain at the start of the Sausalito to Santa Cruz stage of the 2009 Amgen Tour of California professional bicycle stage race.

Reflections on the wet roadway, spray, and the wheels of the competitor’s bikes during the “parade lap” of the Sausalito to Santa Cruz stage of the 2009 Amgen Tour of California. Those who have done enough serious riding to have experienced the sensations of a long ride in cold wet weather will probably identify with this photograph. :-)
