First near Mt. Hood, Goat Rocks, Rainier, Mt.Adams, and Olympics; then later East slopes of Cascades near Snoqualmie-Stevens, Glacier Peak; finally near Rainy Pass, Washington Pass to Canadian border; also Blue Mountains and up along Washington/Idaho border. Only the Olympics may get enough rain barely. LT forecast starting to show rain around Aug 24th.... UW MM5 loop: https://a.atmos.washington.edu/~ovens/wxloop.cgi?wrfd2_wa_pcp1+//84/1

Heard a TV weather person say, “the isolated thunderstorms in Eastern WA will provide welcome relief for firefighters” , Idiot

It’s trying to rain in Wenatchee and on the east slopes right now. I had to hustle to get the lawn mowed.

Right? There is a fire burning in far eastern WA about 6 miles west of Priest Lake....my Mom, were she still alive would be very nervous. I plan to head there this week, always scary there in late Summer. Last July I was there and there was a big lightning storm, it started over a dozen small fire that were luckily quickly extinguished. We have a very big Engleman Spruce tree next to our house, if that ever gets hit, I'm going to have a problem....plus several birds and squirrels would be homeless.

Go placidly amid the noise and waste, and remember what comfort there may be in owning a piece thereof.

Thankfully supposed to clean up near Glacier Peak heading into the weekend. I really don't want to do another long distance backpacking trip in the rain again. https://www.windy.com/48.110/-121.128?rain,48.150,-121.020,11,i:pressure,m:eZmacNi

Its nice when they can pin point it to an area. I guess I will hike just outside of that area and be safe.

Interesting Howard Sheckter comment:
Quote:
It looks like a couple of very active days and nights for both Inyo and Mono County as Deep Monsoon Moisture remains in place and at the same time, and even more importantly, the aid of the jet stream comes to play. Today Thursday, The RT rear entry of a rather weak upper jet will provide added instability to our region this afternoon and evening. Tomorrow Friday, another upper jet, a bit stronger will provide added lift as we are under its Front left exit region. Both of these jets adds to the more passive terrain driven convection that we experience during the Summer. At the moment, the Friday system seems stronger then today’s extra lift. The NWS has Flash flood watches out for Mono and Inyo Counties today, tonight, Friday and Friday evening. As a note, this pattern has the strongest Summertime forcing I have seen in several years!! Highs in Mammoth Thursday
Looking at the recent/ongoing lightning map, there is a super fetch of thunderstorms running from Nevada through the Oregon Cascades, but in Washington, the Olympics (except immediate NW tip) are just squeaking by with a massive number of strikes just offshore. The forecast, though, still shows a bout of lightning storms hitting the SW to SE part of the Olympics and into Seattle, etc. about mid-day. There have been a few strikes thus far between Adams, St. Helens, and Rainier. The UW MM5 also shows more possibility in the Ross Lake to Pasayten area later today. Regardless, we will be getting smoke with tons of lightning strikes in the Oregon Cascades and Western Vancouver Island.

NWS Portland Discussion this morning:
Quote:
Area Forecast Discussion National Weather Service Portland OR 346 AM PDT Wed Aug 10 2022 .SYNOPSIS...The upper low off the southern Oregon coast will continue drifting slowly northward, remaining offshore. A few showers and thunderstorms are possible early this morning north of Salem, but most likely will remain offshore moving northwest. Marine clouds have increased with stronger low level onshore flow this morning, with cooler weather expected today. Dry and seasonal temperatures returns for the remainder of the week, with warmer weather likely starting early next week. && .SHORT TERM...(Today through Friday night)...Water vapor satellite imagery shows the upper level low slowly lifting north just over 100 miles off the northern CA/southern OR coast. Elevated convection overnight has mostly pushed offshore and moving northwest across the coastal waters with a few cells containing frequent lightning. Southerly flow aloft continues through this morning, but mid level moisture and best synoptic support lifts north. CAMs still have not picked up on all of the convection, so confidence on where or if thunderstorms will redevelop across the northern forecast area is low. But will maintain chance for showers and thunderstorms north of Salem through early this morning. 06Z RAP MUCAPE has shown CAPE values of 500 to 1000 J/kg nearest the stronger storms this morning with bulk shear around 35 kt. Forecast soundings indicate higher lapse rates between 700mb-500mb, while the subsidence inversion remains below 850mb. This coincides well with profiler data at Astoria indicating tops of the marine stratus around 1 km MSL (~3000

Cliff Mass says it is actually monsoonal moisture coming up from the SW US (moisture originally from Gulf of Mexico) and not from the Western Pacific, where most of our moisture comes from. It seems this isn't that rare and we seem to get August thunderstorms in Western Washington every other year or so? The increased fire danger sucks but it is kind of a nice treat to have Colorado weather in Western Washington every once in a while.

"Accuweather" says it's going to rain a bit out on the coast today. I have it on good authority that Chanterelles are up out on the coast. On Saturday, Adam (yeah... Adam the mushroom guy) referred to them as "buttons". A little spate of rain will bring them up. Per my phone conversation a couple minutes ago, a little bit of rain fell between Forks and Kalaloch this morning. Might be some oysters showing up too. (Usually on the alders.)(Soak them in salt water to get the worms out.) Remember: NO rain = NO mushrooms What's not to like? Besides, mid-August thunderstorms are an annual event here. Nothin' to get all excited about. The sky is not falling.

I found some hedgehog and yellowfoot buttons on the coast near Kalaloch a couple of weeks ago. From what I hear things are almost always "up" on the coast - we need some rain closer to me so I don't have to make that long drive.

Just got off the phone with pulmonologist's office - rescheduled appointments so I can get in a couple extra days out on the coast next week. Poured down rain here for about 30 minutes at Pt. Defiance. Just stopped. Drive carefully. Roads will be slicker than deer guts on a doorknob.
