Long Range Forecast Discussion:

7 day to 2 week+ forecast (since 1998) - 23 April to 03 May, 2014 - Another low pressure system moves in next Monday through Wednesday with potentially significant snowfall for Tahoe-Mammoth (but looking dry for southern California at this time), as it moves in strong and cold off the Pacific Ocean. The Pacific Northwest will be more favored in this storm, for multiple feet of snow in the Cascades, possibly 1+ feet in the Sierra Nevada. The Inland Northwest will do good as well (northern Rocky Mountains including Big Sky and Jackson Hole), and mainly Tuesday through Thursday for Montana, Idaho and Wyoming. We see this followed by high pressure ridging aloft, building in across the western US Thursday and Friday (mostly sunny with fresh snow for most areas). Then, by next weekend (26th/ 27th) we expect another strong storm to move in, definitely wintry. 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).

Current SST pattern- La Nada

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.

Since we are seeing an actual cooling of the eastern Equatorial Pacific in the last month, and not much change in the 3.4 region, we expect this to not bode well for a shift out of a La Nada pattern, yet. We will keep this outlook updated as more information becomes available.
