Phil Posted May 30, 2017 Report Share Posted May 30, 2017 Verbatim, the 12z Euro would put your cool June call in jeopardy with a fairly warm first 1/3.It looks like an outlier to its own ensemble mean, as well as the GFS/CMC and their corresponding ensemble means. I'm not worried about a warm June in the PNW, unless a brief heatwave lasting 3-4 days is somehow enough to outweigh the slew of cool days that should dominate 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 May 31, 2017 Report Share Posted May 31, 2017 Some of the 12z EPS members (maybe eight) drop 850mb temperatures to between 0C and -2C during the middle of week two over most of WA/BC. That would be pretty nuts for mid-June, looking at ESRL reananalyses for upper level temperatures back to 1946.

Phil Posted May 31, 2017 Report Share Posted May 31, 2017 Another anecdotal quirk favoring a cool summer in the west is actually the deep troughing that's dominated the eastern US since the beginning of May. It's a classic response to IPWP subsidence and/or an EHEM forced waveguide (see 1980, 1983, 1988, 1993, 1995, etc). That relationship reverses around the summer solstice, and often acts to constructively feed back on the EAMT precursors hence reinforced the -PNA/NPAC anticyclone, especially under a background -NAO Personally speaking, I can attest to this relationship. We east coast weenies always dread the combo of a mild winter followed by a cool/wet May, because it almost always leads to a blast furnace pattern in July/August, which will usually feature troughing in the western states. I can't recall this relationship ever failing under a regime of EHEM forcing/Pacific subsidence. 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 May 31, 2017 Report Share Posted May 31, 2017 00z GFS is quite troughy, but it could be handling the frictional torque response incorrectly after 204hrs. Overall, it just delays the progression a bit, and shortens the period of ridging by a few days.

TT-SEA Posted May 31, 2017 Report Share Posted May 31, 2017 The first 7-10 days of June are looking pretty warm on most models. 12Z ECMWF is fairly variable. The weekend is interesting with basically no rain shown but quite cool. No sign at day 10 of a large western trough either. Basically an alternating pattern of ridges and troughs... which is probably quite seasonal for the first half of June.

Phil Posted May 31, 2017 Report Share Posted May 31, 2017 The first 7-10 days of June are looking pretty warm on most models.Except for the 12z GFS, which does weird stuff over Siberia, the modeling is pretty troughy overall @ 500mb for the first half of June, and we're priming the system for even deeper troughing for the second half of the month. At 2m, daytime highs are average cooler than normal on the ensemble means, while overnight lows average warmer than normal, so maybe some marine cloudiness around under W/SW flow or something?
