Mark, I feel that it is worth noting that ENSO data does to some extent exist before 1950, so while the dataset isn’t perfectly continuous (different indicies and whatnot), you can expand the sample size a bit by including pre-1950 events since I feel we have a pretty good idea of how strong El Nino winters behaved in the PNW between 1870 and 1950.
The Nino 3.4 Index goes back to 1871 and shows a number of other strong El Nino winters in that 80 year period. I’ve found 10 other winters that were almost certainly enough to be classified as strong El Ninos.
1877-78: Super Nino very similar to this year or 1997-98/1982-83. This winter was warm and very wet in the PNW, with little lowland snow.
1888-89: A warm and dry dud of a winter, wedged in the middle of an exceptional period for cold and snow around here.
1896-97: Unusual winter with a record cold November and record cold March in Portland, some historic arctic airmasses. Was wet, as well.
1899-00: Exceptionally mild winter even by today’s standards. Near average precip. One arctic blast in February.
1902-03: Fairly wet and mostly pretty mild winter, just some wet snow towards the end.
1905-06: Warm and dry winter, but like 1897 it had a remarkable cold event in March.
1918-19: Near average temps and precip, but with no snow or arctic air.
1925-26: A historic blowtorch of a winter, awful for the mountains and no snow anywhere.
1930-31: Extremely dry and mild, no significant snow or cold spell.
1940-41: You know the drill by now! Very dry and mild with little to no snow around the metro area.
What I find fascinating is how overwhelming this historic signal is. Sure, every event is different and it only takes a few days to turn a winter around here. But with 16 or so events to glean from in our historic record, there’s a decent sample size by now that really indicates a big time chance for a warmer and drier than normal winter with very little snow regionally.
