I think PDO is useful if it has been very sustained like what we're seeing now. It's a symptom of a very persistent pattern. Since persistence is often the way to go in long range forecasting it's useful in that way.
lol. read something other than whatever the eff you read. That happens in all administrations.
And in the case today, the numbers from previous months were corrected upward.
As Dewey said, queue the conspiracy lunatics.
That's definitely not accurate, it looks like there's some incomplete data there and several TR days that likely had 1-2". They also measured 5.5" with the 1/31/1937 storm. I do think Eugene was a hair south of the sweet spot for that one with the dreaded BSF kicking in that evening.
The 1/31 storm was an amazing event that doesn't get discussed too much on here. 16-30" fell in 24 hours for everyone between Corvallis and Longview. It's still Salem's biggest single storm on record. Portland had a 20/16 temp spread with heavy blowing and drifting snow all day and 35-40mph winds. Then there was a good swath of 6-12" to the north up to about Mt. Vernon and south down to Cottage Grove.
This was downtown Salem on the morning of the 1st. Some of the storefront awnings collapsed there.
