7 day to 2 week+ forecast (since 1998) - 30 April to 10 May, 2014 - High pressure ridging aloft builds in across the western US Sunday through most of next week, with some rain and mountain snow across the northwest US and northern Rocky Mountains Sunday and Monday (27th-28th), mostly sunny across all areas Tuesday through Wednesday or Thursday (29th-30th, possibly May 1st), then low pressure moves into the northwest US again late next week, with mountain snows across the Cascades and northern Rocky Mountains then. Winter is not over yet for Western US ski areas, but it seems to be tapering off, in general. CM
Longer Range Outlook
As of now, April 2014, we are continuing to be affected by an ENSO-Neutral, or La Nada Sea Surface Temperature pattern across the Equatorial Eastern Pacific (SSTs near to slightly below average).
The larger time-scale SST pattern in place right now is a cool phase PDO, or negative PDO, which stands for Pacific Decadal Oscillation. This is a more long term pattern (decades), and it has made any recent years El Nino SST patterns weaker.
We expect the ENSO Neutral, or La Nada pattern (almost a La Nina) to continue, though in the last 30 days we have seen more of a trend toward positive SST's along the eastern Equatorial Pacific. We are now seeing a slight trend toward El Nino, and the forecasts from other agencies are calling for El Nino conditions to develop this summer and fall. This would favor the southwest US for heavier rain and snow this fall and mainly winter, after a potentially wet monsoon summer across the southwest US including southern California through Colorado.
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.
Mammoth has 3500 acres of trails, covered in 400 inches of snow, bathed by 300 days of sunshine and that’s just the mountain in an average year. 11,053-foot Mammoth Mountain dominates the Eastern Sierra skyline and the minds and hearts of its die-hard skiers and riders. Yes Mammoth is big. And there’s more to Mammoth winter than one mountain: cross country skiing and snowmobiling over acres of pure white; uncrowded powder days at June Mountain; dinner at Lakefront Restaurant. It's all part of the Mammoth experience.
