snow_wizard Posted August 5, 2016 Report Share Posted August 5, 2016 At this point Saturday looks like a September type day with a cool morning and afternoon temps in the low 70s or so. Could be pretty enjoyable. 1 Quote Death To Warm Anomalies!

Phil Posted August 5, 2016 Report Share Posted August 5, 2016 Back to normal after today for some areas. Might be still close to normal by the 15th after the troughing and then warm spell to follow.Late August will be troughy. Middle is up for grabs.

Phil Posted August 5, 2016 Report Share Posted August 5, 2016 You are probably still off by 7-10 days. Remember early August ridging?Probably not this time.

TT-SEA Posted August 5, 2016 Report Share Posted August 5, 2016 Probably not this time. I'd have said early/mid September without accounting for my slow bias (strong equator-pole conduits this summer). Probably makes sense... first part troughy, middle warm, troughy end. If August does end up cooler than normal then I expect a warm September. Just a feeling based on local history.

TT-SEA Posted August 5, 2016 Report Share Posted August 5, 2016 Also wasn't long ago that you were predicting "flat ridging" through the entirety of August. Its all about definitions. You pretty much call everything troughing out here. So we are talking different languages. This slow moving ULL is a bit of a wrench in the works though. Otherwise it looks about like what I expected. We just call it different things.

Just a feeling based on local history.I'll have a better handle on September in about 10 days, when the NPAC anticyclone starts retreating equatorward. Right now it's a good 15-20 degrees farther poleward vs average.

Yeah... we just call things by different names. Pointless to argue about it. I was not making forecasts using your broader terms. A shortwave ridge for example is just a type of ridge to me. So my terminology will be different. Whatever.

Right now it's a good 15-20 degrees farther poleward vs average. That would be hugely advantageous to us in the winter. The anticyclone being too suppressed has ruined a lot of potentially good winters for us. 1 Quote Death To Warm Anomalies!

snow_wizard Posted August 5, 2016 Report Share Posted August 5, 2016 The WRF shows some places south of Seattle having highs in the upper 50s on Monday. That model isn't known for having a cold bias either. This could be a notable cool period coming up as the min temps are also progged to be below normal. Quote Death To Warm Anomalies!

TT-SEA Posted August 5, 2016 Report Share Posted August 5, 2016 You can definitely tell there are tropical systems messing with the models. Lots of solutions showing fast zonal flow and/or a big ridge in the long range and flipping between runs.

Phil Posted August 5, 2016 Report Share Posted August 5, 2016 A ridge offshore will lead to cooler than average temperatures in the PNW. There's really no support for any sustained ridging in AUG outside clown range modeling that has shown no predictive ability whatsoever this summer. 2 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...
Jesse Posted August 5, 2016 Report Share Posted August 5, 2016 It seems unlikely, but I could picture August ending up above average. It is pretty hard to get two consecutive near to below normal summer months in a row these days. Quote Link to comment Share on other sites More sharing options...
Front Ranger Posted August 5, 2016 Report Share Posted August 5, 2016 12z Euro progression seems reasonable. Fairly brief ridging/heat spike following upcoming ULL, then a nice crash back into default troughing. Potentially wetter pattern towards the end, as well. Quote A forum for the end of the world.

Phil Posted August 5, 2016 Report Share Posted August 5, 2016 I think the ridge will develop just close enough to give us warmer than normal temperatures. We don't need the ridge directly over us in the PNW to bring above average temperatures. Here were the weather conditions yesterday when PDX got to 90. Then ridge was well offshore.Based on what, exactly? Sounds sort of like wishcasting to me. Clown range modeling isn't the route I'd go this year. Remember all that 100+ degree heat consistently modeled for last week? What happened to it? 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...

Just like yesterday looked like mid-upper 80s until the models suddenly warmed up the day before. On a clear day you can as a rule of thumb just add a couple degrees to the MOS output. I saw yesterday consistently pegged around 86-88 for PDX, so a high around 90 fits the norm. Quote Link to comment Share on other sites More sharing options...

Phil Posted August 5, 2016 Report Share Posted August 5, 2016 The "typhoon rule" says nothing as to the location and orientation of the downstream cyclonic breaking. I don't know where this idea that recurving typhoon = western ridge originated from, but it's demonstrably false. There are many example of recurving typhoons that were followed by extended periods of western troughing. It all depends on the nature of the wavebreaking response (assuming one even occurs to begin with). 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...

Jesse Posted August 5, 2016 Report Share Posted August 5, 2016 He's in a general a very good forecaster and he's nailed some big time forecasts well in advance before everybody else. For instance, he was spot on about the 2011 Halloween Nor'easter. He also predicted before Hurricane Sandy even formed in the Western Carribean that it would eventually form into a hurricane and make landfall in New Jersey.It's too bad Hillary didn't chose him as a running mate. 2 Quote Link to comment Share on other sites More sharing options...
