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.
Wide variety of natural terrain which dwarfs other S. California resorts, more on par with the Tahoe resorts in N. California. Most acreage and vertical ft. in S. California, including widest variety of terrain from beginner to expert. Widely spaced trees provide excellent glade skiing along with the only true double black diamond runs found locally. Closest Area to L.A., only 14 miles N. of 210 Frwy in Upland, 30 miles E. of L.A.
