Now that’s more like it.

Have been telling my family in Everett it’s gonna get very wet during the middle of the month. They’re still skeptical…can’t wait to rub it in. :lol:

Everett looks like one of the driest places west of the cascades.

It was incredibly dry up here in July and august. Just 0.17”. September has been wetter so far. 0.52”. 

There were 2 separate light rain events north of Seattle last month that just barely gave any rain south of Seattle…but of course that doesn’t mean everyone got a decent amount up there I know the c-zone areas and Bellingham did alright up there. 0.17” is still better than a lot of places to the south. 

Monthly rainfall-2.23”

Cold season rainfall-

Sub 40 highs-0

Sub 32 highs-0

Sub 32 lows-0

Snowfall-0.0”

Coldest High-63

Coldest Low-42

Yeah... the pattern next weekend puts Everett squarely in the rain shadow.

Took a walk in the neighborhood woods earlier today and this is the first rain that made it all the way down everywhere. Our previous showery episodes were not enough to penetrate in the areas where the canopy was thickest. Now the forest floor is moist everywhere.

Chanterelles should be popping up soon (if not already). Have to head up to the foothills and check.

It's called clown range for a reason.

The EPS kind of likes the idea of another trough around day 10 like the GFS is showing.  Just noticed the ECMWF strongly hints at some frost on day 9 with a chilly airmass in place and northerly surface gradients.  Can't wait for that first really cold morning!

You will not be seeing frost in September.

We get rain shadowed, snow shadowed, wind shadowed, and then when it gets cold enough, winds from the Skykomish valley end up eating snow. Luckley though we are the bullseye for those weird off the Strait pushes and have a great setup for fake cold along with ice.

What about sun shadowed?

That’s favored areas like KOLM and even that’s unusual. Maple Valley will not be seeing frost this September. Mark my words.

He never specified the location did he? Neither did you prior to this post ;) 😁

there was a frost watch east side of the mountains couple weeks ago too.

Spotted this guy trying to infiltrate the home show here in Clark County. He’s looking particularly wooly. Hmmmm…

I once saw stripe-less wooly bear caterpillar. One of the warmest winters on record followed (2016/17).

Forever lost faith in them after that. :angry:

That high of 49 is in the clown range. 🤡🤡

As been pointed out many times... the last day on the 12Z runs is the high through 5 a.m.   😉

Jim lives in Maple Valley. The location to which my claim pertained was thus implied.

Its possible to have frost in late September but definitely would be unusual if it occurs. We had a light frost here on October 1st 2019 within a mile of Puget sound…so I’m pretty sure places away from the sound in the right set up could do it in late September. We hit 36 that morning.

It happens pretty often.  Not freezes, but lows in the mid 30s type frost.  There are some years that have hit freezing in September also.

This actually is a pretty good location for cold low temps.  Not quite at OLM levels (but we do get colder than them sometimes).

The Arlington area is just about as good a radiational cooling spot as Olympia and environs but doesn't get mentioned nearly as much.  We have frosts in September nearly every year.  Currently 63 with the occasional sunbreak.

65/57 0.06” this morning. Wettest day since mid June…also broke a 16 day dry streak today. 

How many days since mid June have you had measurable precip?  Seems like maybe four or so here.

Spent the last week up in Alaska, from Fairbanks up to Galbriath Lake.  The state is so huge, you can see the fall color progression just driving up the Dalton.  Fairbanks was green but turning too, peak around Yukon River, past peak at Coldfoot and snowing at Atigun Pass.  The north side of the pass was past peak but still somewhat colorful.  Aurora were okay on a couple nights, but missed a big show thanks to cloud cover.

Photos in order:

Atigun Pass

Just north of Atigun Pass

Aurora from Fairbanks

Just south of Galbriath Lake

Amazing photos! Thanks for sharing. What a beautiful and wild part of the world.
