BLI snowman Posted July 16, 2019 Report Share Posted July 16, 2019 That is incredible. In February 2014, PDX only got up to 23 one day. Never before had a high been that low since records were taken. On that date. PDX's all time record lowest high is 14 on 12/30/1968. Downtown Portland's record lowest is 9 on 1/15/1888. 1 Quote Link to comment Share on other sites More sharing options...

Phil Posted July 17, 2019 Report Share Posted July 17, 2019 I see. Yeah, you need to fit around their schedule since you're the guest. Yeah, I was looking at weather spark and for Bethesda, the most humid day of the year there is July 29. Looks like you might get some relief end of September. "The muggier period of the year lasts for 4.1 months, from May 24 to September 27, during which time the comfort level is muggy, oppressive, or miserable at least 16% of the time. The muggiest day of the year is July 29, with muggy conditions 66% of the time. The least muggy day of the year is February 19, when muggy conditions are essentially unheard of." https://weatherspark.com/y/21013/Average-Weather-in-Bethesda-Maryland-United-States-Year-RoundAnd my my birthday is on July 28th. Figures, lol. That data seems pretty close, though it looks like it was taken from Gaithersburg Apt, since our average high peaks at 90*F, not 87*F, and the average low bottoms out at 23*F, not 27*F. Temps do peak in late July but dewpoints seem to max out in August. Definitely the least amount of variability during the August/September period..very stagnant minus any tropical systems. 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 "Western troughing literally kills people at this time of year.

Dave Posted July 17, 2019 Report Share Posted July 17, 2019 Of course I was in Texas during the wonderful early Dec 2013 event, where Eugene had some snow and tied their all-time low of -10F. There were some coastal communities who also set their all-time lows. Folks that worked with me at the Pelican in Pacific City said they were in the negatives with snowcover.We had 6 inches in dec 2013. It remained intact on the roads for 6 days. Eugene's all time record low is -12. -10 is second place. Ironically they both occurred on the same date, so the -10 didn't even set a record. 1 Quote Link to comment Share on other sites More sharing options...

Everett is usually around 72 degrees under a trough in late July and maybe 80 under a ridge. With dewpoints in the 40s or 50s either way. The implications are obviously huge!

I’m negotiating with Mother Nature right now, ready to accept a swampy September in exchange for a super duper PNW vortex starting 8/1. The aggregate of convectuve forcing will become EHEM centered with time, so there’s a chance that troughing comes back sooner than we think!
