seattleweatherguy Posted April 12, 2018 Report Share Posted April 12, 2018 You're correct. If the ECMWF seasonals verify we would have a warmer to hotter than normal May to the end of summer here in the PNW. Here are my main takeaways from the brand new seasonals: 1) April will be the end of the rainy pattern that we've seen on occasion this spring. Big shift in the weather pattern takes place late April/early May and ridging starts to develop in the PNW. 2) Strong signal for May to not only end up warmer than normal but to end up drier than normal as well. 3) No signs of any troughing in the PNW as the pattern we have seen the last few summers starts to assert itself. 4) The highest positive anomalies from May and beyond are located in and around the PNW. 5) It remains to be seen if this summer can be as hot as the last 2 but the pattern is there for it to be close.Possible triple digits? Breaking records? Quote Link to comment Share on other sites More sharing options...
Frontal Snowsquall Posted April 12, 2018 Report Share Posted April 12, 2018 I don't believe it.We should have a better understanding a month from now. I want to see if the EURO weeklies/seasonals are correct in the May ridging. Quote Link to comment Share on other sites More sharing options...
Frontal Snowsquall Posted April 12, 2018 Report Share Posted April 12, 2018 Possible triple digits? Breaking records?That's too early to say. The possibilities would be higher though if the seasonals verify. It's harder for you guys up there in Seattle to get to triple digits, it takes a special type of ridge for it to occur.

stuffradio Posted April 12, 2018 Author Report Share Posted April 12, 2018 Scott Sistek is the author... he is the 'Jesse' of KOMO news. He loves rain and hates warmth. And I don't detest the weather for 10 months. But I do complain when its much more persistently wet than usual as was the case in 2015-16 and in the spring of 2017. And that is how April 2018 is playing out as well. You never acknowledge that. He is? I have never found him obsessing about rain much. I send him messages from time to time and he usually responds.

TT-SEA Posted April 12, 2018 Report Share Posted April 12, 2018 Well... the ECMWF went from showing a nice day on Saturday and then just some scattered showers on Sunday to now showing non-stop rain from Friday into Monday here. Probably will not stop raining for even a hour. Amazing that we have another complete washout of a weekend ahead. And its all because the trough is not a deep as originally shown.

I only have access to the free edition. To be fair since 2015, this model probably has done a better job because we've seen record breaking heat the past few summers. The key takeaway I took from it was that the highest positive anomalies were closer to the PNW than any other area. Also that Hudson Bay low depicted from May to July is another indicator for warmer weather here in the PNW. Quote Link to comment Share on other sites More sharing options...

I was scrolling through web cams on that site and Bozeman Pass even has open ground and wet conditions right now. There are some patches of bare ground, (brown and ugly this time of year) especially in south facing areas here now. Our backyard is still pretty buried in 2 feet of snow though. We're only 300' lower than Bozeman pass so pretty similar conditions. I actually saw a few blades of green grass coming up yesterday in town!
