Although, snow in the month of May is not unusual here in Mammoth, and in fact happens in most years, the persistence of cooler then normal temps is. Just look at the snow pack for this time of the year. It is still at least 150% of normal. The roads in the lakes basin and down to Reds meadow is probably with still 7 to 10 feet over the top and it is likely that the road over Tioga will not open until well into June. There are the reports of 75 foot snowpacks covering roads in the mountain areas of the pacific northwest. Must be Global Warming? ;-)
Blame it on the negative PDO and a very slow awaking Sun from a long hibernation.
The negitive phase of the pacific decadial oscillation (PDO) is going strong and if history repeats itself may continue more on then off for the next 20 to 30 years. That means that the SSTs over the eastern pacific are colder then normal and that the west should have more precipitation and colder WX in the years to come. Summer may tend to be cooler and winters earlier and longer. El Ninos will tend to be weaker or shorter lived. If you want to get an idea of the weather for a negative PDO just study the weather of the 1930s, 40s and 50s here in this country. Watch La Nina this year. It is currently weakening and should pretty much be gone by Summer. However, watch and see if it does not return this Fall!
We'll need at least the next decade of data to assign credibility to the competing climate theories, but it's pretty clear who won the first round.
