A summer like 2011 or 1993 would probably be a massive shock to the system especially for people who’ve moved to western Washington in the last 10 years. Hard to imagine pulling off something similar to either of those years nowadays.
IIRC May at SEA warmed +1.6F from the 1971-2000 to the 1981-2010 averages…and almost all of our warmest summers have been in the last 10 years. Everyone whos lived here a long time can tell the difference from the past compared to pre 2011.
Is it so hard to accept our warm season as a whole is trending warmer and in some years drier? The warming has been much more pronounced than the drying. The 1991-2020 averages are going to be a big jump over the 1981-2010 ones even.
Yes but warmer and drier springs are becoming more frequent overall and years like 2010-12 and 2022 are becoming less frequent. Obviously shoulder season warmth has happened in the past but there’s no denying there’s been a shift especially in the last 15 years with an exception of a couple years.
