That winter was a fascinating case study in the basic timeline of our inversion season in the PNW. Check out Pendleton's temps that winter. It was thoroughly ridgy basically the whole way through. But the cold/foggy ridging turned on a dime in the 2nd week of February and never looked back, flipping literally overnight to warm/sunny ridging on the 9th of February. This year was kind of similar. January was a classic inversion. In February it broke due to the higher February sun angle. After that it was intensely sunny. I can't recall a sunnier February. February is normally one of our gloomier months. 2 Quote Link to comment Share on other sites More sharing options...

TT-SEA Posted June 3, 2022 Author Report Share Posted June 3, 2022 4 hours ago, TT-SEA said: Because it interrupted the ENSO cycle and led to a Nina? Maybe so. But even a Nina does not mean rain this persistent here. To be fair... this is based on the assumption that it will rain almost every day for the next 2 weeks which is what the ECMWF and EPS are showing. That would be a 2.5 month stretch (75 days) with rain almost every day here and that is exceedingly rare even in the fall and winter. If we get a week of dry weather coming up then it paints a different and more typical Nina picture in which there are some meaningful dry periods even though its wet overall. I just don't see that happening. This was the original post that got a few people started about feelings. Which are of course irrelevant to statistics. I am going to move all subsequent posts related to this over to the preference thread. My post above had nothing to do with preferences and I stand by the information. 2 Quote **REPORTED CONDITIONS AND ANOMALIES ARE NOT MEANT TO IMPLY ANYTHING ON A REGIONAL LEVEL UNLESS SPECIFICALLY STATED** Link to comment Share on other sites More sharing options...

NWbyNW Posted June 3, 2022 Report Share Posted June 3, 2022 I was rudely awaken before my alarm clock this morning. At 6:33am I heard a loud bang/crash and was awaken. For a second I wondered what had happened, then I heard some rumbling and more thunderous booms! I was awoken by thunder! Wow! I opened the blinds and reached for my camera. It was pouring down rain and nature made her own alarm clark. I don't think I've ever been woken up by thunder. Very cool, especially to have thunder twice in less than 48hrs. I stayed awake and listened and watched the rain before getting ready for the day. As of 2:15pm, it is still raining heavily, though at times it slows to a sprinkle. Currently 57F, and after about 7:10am, the thunder had ceased. Very cool 48hrs! Here is some photos of the wet stuff from 6:33am this morning and one from a minute ago. It's like a shallow pool of water everywhere! Big droplets! 7 2 Quote Link to comment Share on other sites More sharing options...

snow drift Posted June 3, 2022 Report Share Posted June 3, 2022 We had two tornadoes spawn from a thunderstorm in early May. The storm was rather vanilla. It featured a few rumbles of thunder and some rain. The two tornadoes caught everyone by surprise, but they were only little guys. They were both rated at F0. They were so cute though. When they get bigger, they plan on moving to Kansas or Oklahoma. 5 Quote Link to comment Share on other sites More sharing options...

The Upper Skagit Valley has warmer summer high temps than Bellingham at the same latitude by a pretty decent margin: https://en.wikipedia.org/wiki/Diablo_Dam#Climate Likewise compare Eugene summers to Grants Pass / Medford summers. The Rogue Valley is significantly warmer (even despite higher elevation) which has a bit to do with latitude but geography explains it a bit better. While Eugene is separated from the ocean by the Coast Range the Rogue Valley is shadowed by the Siskiyous, a much higher mountain range creating a strong shadow effect more akin to the Cascades. In fact the Siskiyous SW of Ashland even have native growing sagebrush and the Scott Valley just across the state line is home to the westernmost native sagebrush in the country. 2 Quote Link to comment Share on other sites More sharing options...

The PQR office seems to have recorded around 19 so it looks like this location did a bit better. Surprisingly I had a higher snow depth on the morning of 1/11/17, but that was because a bunch of snow was dumped all at once so there was no time to melt. 1 Quote Link to comment Share on other sites More sharing options...
