Temperature anomalies should not be controversial at all this month as data have shown it’s been relatively closer to average at least for W.Wa. This should no longer be a 2015 comparison and probably shouldn’t be to begin with. 2015 was an exceptional year and we should just let it be for what it was.

snow_wizard Posted July 23, 2021 Report Share Posted July 23, 2021 I was at Ocean Shores this past week which is why I haven't posted. It was certainly interesting how the nicest days were the ones that were cloudy in Seattle. At any rate this has been a purely enjoyable summer outside of the one week from hell. In fact if you take that week out SEA would be a tad below normal for the summer to date. Looking ahead the center of the high over the CONUS remains displaced unusually far east so things aren't going to get all that hot any time soon. Probably a few solidly warm days, but nothing too out of the ordinary. 1 1 1 Quote Death To Warm Anomalies!

Phil Posted July 23, 2021 Report Share Posted July 23, 2021 Basically a re-run of late June post-WPAC pulse, except different external expression thru seasonality/wavenumber. Either way it’s a similar theme..lag time (of unpredictable duration) in +TNH pattern following the WPAC event. How long is TBD, but the tropics don’t stay in WPAC mode for long. And now the GEFS and EPS align, so maybe we’ll see some clarity in the signals once the forcing flips at the end of the month. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Phil Posted July 23, 2021 Report Share Posted July 23, 2021 Also I’ve been digging into summers like this and it struck me how descending E-QBO seems to be a theme in warm PNW summers under neutral/cool ENSO conditions. It makes sense in theory, but I didn’t expect to see such a strong relationship in the NH warm season. But since QBO seems to affect tropical convection/RWB year-round, maybe it’s something we should consider.

James Jones Posted July 23, 2021 Report Share Posted July 23, 2021 4 hours ago, BLI snowman said: The second half of August is our best case scenario for some decent rain to return, although the last two decades have taught me not to put any faith into August. If balance was still even remotely a thing in the climate universe then one would historically anticipate some significant rain and summer coming to a screeching halt around August 20 given how crooked things have been. My suspicion is that it'll wait a few more weeks this year just for some extra torture. 1977 might be the ultimate example of this. The first 17 days of the month was perhaps the hottest 17 day stretch on record, then we crashed into fall and never looked back. The last 10 days of the month had 3.59" of rain at SEA, 4.17" at OLM, and 3.26" at PDX. Even a pale imitation of that would be a godsend for our ecosystem. 3 Quote Link to comment Share on other sites More sharing options...

It’s far from a stretch to say this summer is on track end up close to as hot as or even hotter than 2015 for many parts of the region, fog belt locations within five miles of Puget sound notwithstanding. 3 Quote Link to comment Share on other sites More sharing options...

That's why I handed off the LR forecasting reins to you years ago. I agree to an extent. Large number of contradicting variables is a given, but the question is *which* variables will run the show? Because the same forcing can trigger a completely different response from year to year (and certainly from season to season). The in-situ system state matters. And that’s the difficult part. At least for me. Some years things are more linear and easier to project (like 2019), other years it’s more complicated with lots of state-dependent responses and interference (like this year). I’m finding it borderline impossible to make subseasonal predictions this year. Low frequency/seasonal was more clear (large HC/expanded 4CH). But that doesn’t tell you much.
