7 day to 2 week+ forecast (since 1998) - 20 to 30 April, 2014 - After the 20th (after this weekend), the overall pattern goes from high pressure ridging and dry for the most part, to unsettled with potential rain and snow, as large scale low pressure develops across the west coast and western US./ This unsettled pattern should continue through much of April, possibly switching back to high pressure and sunshine in the last week of April.

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, and in the last 30 days we have seen more of a La Nina pattern develop with colder SST's along the eastern Equatorial Pacific and even the region 3.4 always referred to, though less so in 3.4. We are not seeing the trend toward El Nino yet.
We will keep this outlook updated as more information becomes available.

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.
