7 day to 2 week+ forecast (since 1998) - 07 to 17 October, 2014 - It looks like we may be experiencing a period of dry and milder weather almost this whole period of time, under an upper-level high pressure ridge across the western US (almost all of the western US may be affected by this ridge, with warmer than average weather and mostly sunny skies). Even southwest Canada, BC and AB, should remain dry through most of this period. We will be watching. CM
Longer Range Outlook
As of now, October 2014, we are still on a path to see an El Nino Sea Surface Temperature pattern hold across the Equatorial Eastern Pacific. Sea Surface Temperature Anomalies yield a weak El Nino pattern across the eastern Equatorial Pacific (El Nino development is on track, but it will be weak, still favorable for California and the desert Southwest, plus much of Colorado and northern New Mexico).
A weak El Nino is now being predicted for this fall and winter, into early 2015. It looks like the early season (October/ November) will see more rain and snow for southern and central California, Arizona, New Mexico, Utah and Colorado. This should help kick off the early season for places like Mammoth Mountain. This should also help build up a better than average base of snow for Aspen-Snowmass and Taos Ski Valley. Temperatures are expected to be near and below average for these areas as well, which helps. Maybe Thanksgiving will be pretty good for many more areas across the southwest, and even for Squaw Valley in Tahoe. The Northwest US is expecting a drier and milder than usual fall, with less snowfall than average, though with their usual heavy snowfall, especially in the Cascades, this drier/ milder than average fall season could still be good for resorts across the northwest US, mainly along the Cascades, less so inland.
The larger time-scale SST pattern in place right now is still a cool phase PDO, or negative PDO (Pacific Decadal Oscillation). This is a more long term pattern (decades), and it has made any recent years El Nino SST patterns weaker (it looks like this is the case with the current El Nino, which was expected to be strong initially.
To summarize, the possibility of an El Nino pattern this fall and winter are "likely". Forecasts from other agencies are calling for El Nino conditions to hold this fall and winter. This would favor the southwest US (including southern California and across to Taos Ski Valley, even Aspen, Colorado) for heavier rain and snow this fall and mainly winter (2014-2015), after the wet monsoon summer across the southwest US (we forecast this in the spring). Northwest US areas, and southwest Canada, along with northern Colorado through Wyoming and the northern Rocky Mountains, should expect a drier than average, or near average snowfall winter (2014-2015). Tahoe/ Mammoth should see near average snowfall this winter. This is our outlook for now, and we will update as more info becomes available. All of this information is generated in-house.
We will keep this outlook updated as more information becomes available. If you want to know when the snow is coming (and be able to set unlimited alerts for any resort), within 5 minutes or less of us (our our sources) entering the data into any of our forecasts, be sure to download the app.
The closest major family resort to the Bay Area and Sacramento, Sierra-at-Tahoe is Lake Tahoe's best-kept secret. The resort's North facing location keeps the snow in great condition for days and with a variety of terrain to choose from the entire family or group of friends can find something to cater toward their ability. Sierra is one of the only resorts that offers beginner, intermediate and advanced terrain all accessible from the summit lift, allowing groups to ride together while still enjoying the runs they want to hit. Five backcountry gates keep expert skiers entertained for hours and give breathtaking views of Lake Tahoe along with quite, uncrowded lines you can't find at other resorts. With new terrain park features, access to backcountry terrain, and new adventure parks for kids, Sierra-at-Tahoe Resort has something to offer everyone. Sierra-at-Tahoe is Northern California's home away from home. At this resort, guests are greeted by name and treated like family. Located on Highway 50, Sierra is the closest major snowsports resort to San Francisco and Sacramento, yet it's just a stone's throw away from the glitz of South Lake Tahoe and a multitude of hotel and casino lodging options. Convenience, value and great service are just a few of the words that summarize Sierra. Another asset is the location of its slopes, which are wind-protected and cradle the fresh powder for days. Skiers and riders of all ability levels can easily find their niche here, whether it's exploring the never-ending tree skiing, cruising down a 2.5 mile beginner run from the summit or hucking themselves off a tabletop in one of the many terrain parks and pipes scattered throughout the mountain.
