10pm Wednesday…
It was another scorcher today all across Oregon and Washington, the only comfortable temps were at the coastline
Portland once again tied it’s warmest day of summer at 98 degrees. That makes it our 11th day hitting 90. In case you wonder, the 30 year average is between 13-14 days per season.
Some marine air is pouring into the western valleys this evening. I see Kelso, Eugene, & Corvallis are dropping into the 60s already, even under thick cloud cover. Speaking of…
Models have done very well showing an upper-level disturbance moving north over the Pacific Northwest tonight and Thursday. That’s why clouds suddenly showed up around sunset. That gives us a very warm night, but also a chance for a shower. You may wake up to wet streets and/or showers Thursday morning. There is even a slight thunder chance, although at this moment the GOES-17 lightning mapper is showing nothing west of the Cascades. There was ONE strike west of Corvallis a couple hours ago and one more east of Lincoln city around 9:45pm. You can find that here: https://rammb-slider.cira.colostate.edu/?sat=goes-17&z=4&im=12&ts=1&st=0&et=0&speed=130&motion=loop&map=1&lat=0&opacity%5B0%5D=1&hidden%5B0%5D=0&pause=0&slider=-1&hide_controls=0&mouse_draw=0&follow_feature=0&follow_hide=0&s=rammb-slider&sec=conus&p%5B0%5D=cira_glm_l2_group_energy&x=7265&y=2864
Once we get beyond tomorrow morning I see a typical late summer weather pattern through the early part of next week, including Labor Day Weekend. That’s varying amounts of morning clouds and afternoon sunshine each day. At this point it appears a dying system moving onshore Saturday will bring showers out there and maybe a shower makes it into the valleys in the afternoon too. Maybe.
Next week should feel a bit more like fall as temperatures only reach into the 70s or 80 each day along with the decreasing sun angle. Thick morning clouds at times will add to that feeling as well. The ECMWF ensembles hint an upper-level trough could bring showers either Tuesday or Wednesday. No hot weather in sight!

Had about 45 minutes of lightning, thunder and decent rain early this morning in Oregon City. just had another shower, then… full sun. Maybe more action this afternoon,
That loop is fun to see.
I woke up at 3am today due to some rumbling thunder near my house. Man, it sure cooled down quick overnight. Rain showers should persist until late morning today. The latest batch of showers brought me some dense fog, Nice! Those living in the N Portland/Battle Ground area were hit hard with thunderstorms and lightning. Sorry for those who got their power knocked out :(. Anyways, let’s keep the rain coming through!
Heard a tiny tinkling on my rain gutters last night at 11pm. This morning everything is dry, so it obviously fizzled out for Hillsboro once again 😦
What a storm!!!
Enjoy. 🙂
Very nice!
FYI… KGW’s radar is a great resource when KRTX is down like now. 0.00” of rain here, but I see some areas a little to the east got a decent soaking. Hopefully more to come.
NWS has been running a “mixed mode” radar composite for the last day or so. I’m not entirely clear on their explanation, but it appears to emulate RTX coverage and be handling the Portland metro area really well.
We got a good 10-minute soaking downpour around 2:00 this morning and we’re probably less than a half mile from you, so apparently there were micro cells in some places, none in others. But the thunder! Sounded like a naval bombardment from a WW II movie.
KGW got rid of their radar about 10 years ago
Hmmm… What is the source of their radar data? Is is not KRTX.
When thunder roars get outside!
Booming and banging pretty good in the land of gravelly plains.
Reporting in From Castle Rock, Wa.
Hearing more thunder again. So much for sleeping.
Milwaukie got pounded.
Finally!!
Video will be uploaded shortly…
Mostly moving out of Milwaukie, Gladstone, Lake Oswego, etc. now. Some incredibly loud booms around here. Four completely shook my house and one set off car alarms… Been a while since I’ve had that happen. Rain came in pretty heavy… Oh and another flash just now.
Huh, over 13,000 out of power right now.
Very distant thunder and saw a flash outside… At least I think I did.
Yeah, definitely just saw a flash of lightning off to the ESE.
Lightning strike to the West of Corvallis, moving toward the NNE. Lack of radar coverage making it hard to track.
