October 2023 Weather in the PNW

[Ken in Wood Village]

I thought I would post the thunderstorms up in the Seattle area. 

[TacomaWx]

Several flashes and thunder here in the last couple minutes. This is the most interesting the weather has been here in awhile. 

[FroYoBro]

It is interesting how the radar hasn't really shown much, but been getting a lot of drizzle and light rain through the day here. I love the drippy weather.

I was thinking that today’s weather is about as boring as it gets - cloudy, dry and calm. And then out of nowhere…

Thunderstorms on top of a marine layer is one of those west coast weather things that is unique, weird, and really cool. Who in their right mind would look outside and think the atmosphere is favorable for thunderstorms today? 

It's surprising how loud the thunder is here in Lakewood, despite the unassuming overcast sky.

Originating from the Comet IP/Halley, also known as Halley's Comet, the Orionid meteor shower peaks across the Northern Hemisphere every October. This year, the peak activity happens on Oct. 21, offering the best chance to see the meteors in action.

I should probably bring in the lemon tree tomorrow, don't want to lose my fruit.

Gone all day fishing and hiking. It was nice up in the Cascades of Clackamas County. Cold. 33 and foggy around 8 AM, but it warmed up nicely after. On the way home it was very thick fog at Government Camp and heavy drizzle from Zigzag to east Gresham real ugly stuff. I just looked at 12z runs. Did the Euro cave to the GFS? It sure looks like it. Interesting. That's a chilly trough.

Borderline 2002 stuff, most likely will not pan out that way and I hope it does not.

Could be some of earliest sub-530 thicknesses on record…

Pretty wild. Last year we got in that range with the November 2-3 trough. 

[TigerWoodsLibido]

Did the 534dm thickness line make it this far south in 2002-03?

I’m in the purple! Though it’s the GFS so there’s a great chance that won’t happen.

I wanted to look for the cold air up in Canada and I think I found it. I downloaded a GIF of the mid-level water vapor satellite picture but took a still shot and drew a line where I believe the colder air is. I then looked at the temperature map and drew a line like the satellite picture and look what I found. Some really cold air. It's filtering down our way. I don't think our area will get that cold like it is up there but I think we will feel a bite in the air, especially in the mornings. 

The 00Z GFS looks good still, let's hope the Euro looks the same
