Are you really seriously trying to argue that bigger/prolonged La Ninas and -PDO stretches don't historically correlate to cooler summers (and springs) in the PNW? Do you think 2010-12, 1999-01, 1989, 1974-76, 1971, 1954-57, 1916, 1909-10, 1893, 1890 were all just really big coincidences?

I might have found something. Granted this is the GEFS. I took another closer look at the 18z GEFS. Day 10-16 honestly looks a bit promising. A lot better than the pattern now. Note the stubborn SW ridge finally scoots east becoming an eastern US ridge. Upstream the positive anomaly is too far west, but the flow shifts and might allow for Mt. Snow. 850s show a massive reservoir of cold air is positioned waiting to our north. We just need the Pacific to quiet down and we could possibly work with this just need the Aleutian ridge to move into the sweet spot/150-160 W.

It will be fun to watch Johnson Creek rise. It can become raging. Also, a smaller tributary Butler Creek around the Binford Lake area in Gresham will be crazy!

Look up their anomaly from Nov 2022. Or Feb 2019.

This was our side deck on closing day, April 25. Lol, took another month to fully melt this stuff. There was still 10 inches of LE in this snowpack at this point.
