Jesse Posted May 28, 2017 Report Share Posted May 28, 2017 I have been sneezing and blowing my nose quite a bit the last couple of days. No complaints on the weather though. Pretty much perfect.I will gladly bleed out my eyes as long as it's warm and the sun is shining. Quote Link to comment Share on other sites More sharing options...

bainbridgekid Posted May 28, 2017 Report Share Posted May 28, 2017 My son said they found spots close to 70 on Sammamish this afternoon when he took the boat out with friends.Awesome. The combination of a cold Winter followed by such a chilly and rainy Spring had things way cooler than normal till this warm spell, so it's nice to see them recover so quickly. Planning to get out on the water tomorrow and/or Monday.

You were just talking about the 00Z GFS during week 2 so I checked out what it showed.Haha, well I wouldn't say "impossible". Either it's handling the convection incorrectly (which is very possible, the GFS is godawful with convection, even worse than the CMC and JMA), or it's handling the Eurasian wave train incorrectly (which it did throughout last winter, most notably a few days before the early February event). So..flip a coin and pick your favorite model.

Brennan Posted May 28, 2017 Report Share Posted May 28, 2017 Also, the CFS/EPS weeklies and GEFS/EPS operational ensembles both depict an anomalous weakening of the Asian monsoonal circulations (relative to climatology) during mid-June, almost to the point of a complete shutdown and return to a winter-like EHEM circulation. If this holds true, the mid/high latitudes experience a very large energy deficit. Could be an interesting setup as we approach the summer solstice.What does this mean for weather in the Bering Sea this summer? I'm particularly interested in the Bristol bay waters between late June and Mid July. Thanks Phil Quote Link to comment Share on other sites More sharing options...

Thanks PhilWell, it would (theoretically) lead to a tighter meridional temperature gradient (warmer tropics, colder poles) which is a boundary state that favors a stronger zonal jet stream. Of course, this doesn't factor in intraseasonal influences, which will interfere and affect the wave train/exact latitude of said jet.

WeatherArchive Posted May 28, 2017 Report Share Posted May 28, 2017 The string of warm nights of the 2013 regime are over. Even during this *heatwave* we have been going at or below Yesterday morning I sneaked in a 47F and it was chilly! Today it is 50F for the low however the humidity is at 96 relative so it contrast it doesn't feel that chilly and we don't have the heat on. Yesterday the humidity got no higher then around 80 relative. Clouds are starting to form that are blotting the sun out. On church day of course. Now why couldn't we have had these clouds ALL WEEK! huh? The mornings have been insanely bright like a giant spot light going thru your window but evenings have been perfect on the contrast. Yesterday and the day before was as close to a blue dome sky you will get. Once in a while I've seen better without the farm haze. Quote Link to comment Share on other sites More sharing options...
WeatherArchive Posted May 28, 2017 Report Share Posted May 28, 2017 However, interesting to note the EAWM (East Asian winter monsoon) has been stronger in recent winters, opposite of the EASM (East Asian Summer Monsoon). http://i724.photobucket.com/albums/ww243/phillywillie/Mobile%20Uploads/56F6FEDC-CA0E-4340-9A70-72DE06D21069_zpsqpnrqfxi.jpg The stronger EAWM = increased WHEM tropical convection and poleward mass transport = -NAM bias. In other words, a stronger EAWM favors increased winter blocking. Weak 1990s EAWM coincided with +NAM, strong EAWM during the 1960s/1970s and mid/late 2000s/early 2010s coincided with a generally -NAM. The EAWM weakened again during the most recent 2012-present period. http://i724.photobucket.com/albums/ww243/phillywillie/Mobile%20Uploads/5D7CBEA0-9014-4120-8A31-69CD75B4DE76_zpsxntdjmmn.jpgWow!

WeatherArchive Posted May 28, 2017 Report Share Posted May 28, 2017 Never doubt Phil. Timing might be off a little bit... but he will get the big picture right most of the time.In this case a lot bit off but either way night times have been reasonable compared to the string of 60+ lows in the 2013 regime. I'm happy with that! Quote Link to comment Share on other sites More sharing options...
Phil Posted May 28, 2017 Report Share Posted May 28, 2017 Wow!

I'm happy with that! No doubt this pattern has been a challenge for me (and the models too). Honestly, I've been all over the place...so many moving parts right now. Not to mention an extratropical domain that seems almost disconnected from the tropical forcings for the time being. Things should become more coherent with time, but for now the situation remains fluid.

Once that happens, troughing will return in a big way, and will likely last for several weeks following the termination of the wave upon leaving the Pacific.

I know Phil was talking about the trough axis reaching this area roughly around the first week of June but it seems like it has already set up shop here. We've been stuck in the 50's and 60's here while the western lowlands have been experiencing plenty of 80's to 90º days it seems.
