  • We are now well into the second half of the month of April, and there have still been no 70-degree days at Columbia Gorge Municipal Airport, also known as DLS.  A little over a week ago, we celebrated the “Latest […]

  • Rumors of ol’ El returning for summer 2017 have been percolating through meteorological echo chambers for the past few months, but in the past few days, mainstream media outlets like the New York Times have […]

  • After such a cold, snowy winter and the strongest April windstorm in the Portland metro area since April 14, 1957, I’m sure many of you will be relieved to hear that tomorrow is shaping up to be the warmest day of […]

    • Charlie, I am a newbie to this site, but am enjoying it. I have a question for you or anyone else involved with Charlie’s Weather. My wife and I are thinking about relocating to Eugene. We have heard that in a normal year (so what is normal these days of global weirding) Eugene has a wet season from November to May and a dry season from May to October. Has that been your experience?

      • Hi Sharon! Thanks for joining, and I’m glad you are enjoying the site! In my experience, the heaviest rainstorms occur from Halloween through Valentine’s Day, with frequent (but decreasing) showers after Valentines day. The ramp up into stormy season is a lot quicker than the ramp down into our quiet season. The hottest months are July and August… it can reach 100 on occasion, and it is very dry. I’ve attached some climate averages for Eugene below.

        • Thanks, Charlie! A couple of follow-up questions: are there data yet on the impact of global warming on this pattern of 4 months dry (quiet), 5 months wet, and 3 months transitional? Also, do El Nino and La Nina events affect this pattern? Sharon

    • Hi Sharon. Research done by Mike Warner, Eric Salathe, and Cliff Mass at the UW suggests that the flooding “atmospheric river” events we see in the winter will become more intense and carry more moisture. Dr. Mass and others have also found that global warming will result in an increase in low, marine clouds during the late spring/early summer. Mountain snowpack in the winter will decrease dramatically at lower elevations, particularly after 2050.

      El Nino events tend to make us warmer and slightly drier, while La Nina events tend to make us cooler and slightly wetter. However, some years are exceptions – the winter of 2015-2016 was the wettest winter on record for the Pacific Northwest, and it was also one of, if not THE, strongest El Ninos on record. Our biggest storms have tended to come during neutral years, but given our short period of record, it’s still not certain whether this is coincidence or whether there is a strong link. There does appear to be some correlation though.

      El Nino and La Nina events primarily affect our weather from January through March. They have a relatively small effect on our weather throughout the late spring, summer, and autumn.

      • Thanks, Charlie! Now I know more about what to learn about on your site – like atmospheric rivers and marine clouds. I appreciate your time and efforts. Sharon

    • Of course, my pleasure!

  • So the final numbers are in for the month of March. As you all know, it’s been a pretty toasty one this year, but I had no idea exactly HOW toasty. Our average temperature at DLS was 52.9 degrees F, with a high of […]

  • March 2017 has been extremely wet across the Pacific Northwest, but it hasn’t been particularly cold. My forecast for strong, 2009/2012-esque cold departures ended up busting completely, and temps are running […]

  • What a night!

    Following a beautiful spring Monday, evening showers and storms began popping up near Cave Creek. I captured a few shots of the distant lightning.

    If that wasn’t enough, ANOTHER storm […]

  • Hi everybody! I apologize for the delay in posts over the past several days – I have been working very hard on my Grads scripts and have been trying to figure out how to get them online! For those who don’t know, […]

  • It was a beautiful early spring day in the Gorge for Equinox Eve: mostly clear skies, comfortably cool temps, and a dry and breezy east wind. Despite all the sunshine, temps in The Dalles were about 3 degrees […]

    • Things have been slow to bloom on the west side too. I usually start feeling my seasonal allergies in the first week of March, but I’ve only started feeling them over the past couple days.

      Great photos Karl!

        I would say that everything in The Dalles is about 10-14 days behind the “30 year pheno” average, this late-winter and early-spring. And a full month behind 2015. That year the apricot and plum and very first magnolias, peeped open in the last week of February. This year they will do so in the last week of March instead.

        Had late February through mid-March been colder, with more deep Gulf of Alaska troughs and maybe even a late-season tease of arctic air? Everything might have been an extra 7-10 days later still.

  • UC Berkeley’s Amateur Radio Club and the East Bay Amateur Radio Club in California launched a balloon with a tracking device Saturday, which allowed radio amateurs to see how far the balloon went, how high it […]

    • Wow, this is awesome! I’m really into vintage audio equipment (especially the giant “monster” receivers of the late 70s), and my explorations there have taught me a little about ham radio. It’s something I’d like to eventually get involved in when I get a little more settled down here in Portland.

      I’ll check out the APRS, thanks for the link Mark!

    • This is really interesting! Thanks for sharing! Who knew a balloon could get that high in the atmosphere?! (OK, “who knew health care could be so complicated”–I get it!)

  • After a long and dark Pacific Northwest winter, even the biggest storm and snow fans look forward to the longer days of spring. And perhaps no day is anticipated more than the spring equinox, which is, […]

    • This explanation is a little above my pay grade, but I got some interesting tidbits out of it. Thanks!
