Lets just call la Nina "the windy Bitch" and forget about the models. 8) That's not to say we won't experience a few Arctic Outflow events :!:

Well, hopefully a warm and wet Spring with limited forest fire activity this Summer. Doesn't sound good for the Westerlies though!
In Summer, are El Nino years generally big evening Westerlies/heat, and La Nina cooler/wetter with mild SEs and alternating Ws? Or is it not that simple to generalize like that?

A transition from La Niña to ENSO-Neutral is likely in the next month or so, with an 80% chance of ENSO-neutral during May-July 2021. https://www.cpc.ncep.noaa.gov/products/ ... disc.shtml

Bobson I suspect your friend Is/was a Ferrari fan. Cliff Mass my oft. quoted Seattle meteorologist prof. says that spring is subject to a "spring forecast barrier" so stay tuned. 8)

https://www.cpc.ncep.noaa.gov/products/ ... disc.shtml " ENSO-neutral is favored for the remainder of summer (~60% chance in the July-September season), with La Niña possibly emerging during the August-October season and lasting through the 2021-22 winter (~70% chance during November-January). "

"So let me get to the punch line. During La Nina years, the Northwest tends to be cooler and wetter than normal. Typically more snowpack in the mountains. And increased chances of lowland snow. " (Cliff Mass) https://cliffmass.blogspot.com/2021/08/ ... yHNu6CcwX4
