Seriously. Why would someone want it to be hot for a backpacking trip..

If his trip is in the WA Cascades then that ridge probably means sunshine and low 70s during the day and chilly nights.     

That actually sounds perfect and probably much more enjoyable than sideways 40-degree rain which can also happen in September at higher elevations.

Ended up with morning fog and a 78/51 spread Friday. 88/52 yesterday, nasty white-ish color returned to the sky as it often does during warm days lately. 

Some scenic high clouds today but temps are still overachieving handily. 81/55 spread so far but should tack another degree or two on. Looks like we have our requisite bi-monthly major heatwave to look forward to starting later next week.

80 at SEA on the hour.

The day after this, I'm going to a Cougars game with my son. So glad for the shaded seats.

89F was our high today I think. Just dropped below it about 30 seconds ago.

80/53 on the day. Currently 71. Sprayed weeds, cleaned up the shop, pulled out the generator and gave it a Check up and a run to make sure it’s ready. also put the jetski to bed until 2024. 
 

It’s coming.

I think you purposefully posted this to troll the WV folks with their 90s. *nod*

Was now just watching the 18z loop and noticed Lee taking a last minute turn to swipe at NE before heading out. Dafuq.

70s in the mountains is pretty hot if the hike crosses exposed terrain.

Actually not... wanted to highlight how nice it would be in the mountains.

Some 72/48 type days with a September sun angle sounds quite nice for hiking.   I am sure that is why he happily posted the ridge map in the first place.

I’m just pointing out you probably aren’t the one to talk about this.

Roasting hot is no good. Relatively warm is ideal when campfires are banned everywhere. Also, it makes refreshing dips in lakes or rivers more tolerable.

I thought I'd also mention that most of the backpacking trips I have taken were when I was younger and before our climate turned roasting dry and hot and campfires were never banned.

The weather?   Yes I can talk about that.   I know what its like in the mountains in exposed areas.   I also know that sun angle is significantly lower now and I personally would prefer the same weather that @Slushy Inch would prefer for his trip.   

[Cascadia_Wx]

Ended up with an 82/55 day here. Temp leveled off in the afternoon with a SW wind. Some high clouds moving in now, could make for a nice sunset.

Lee is just coming into view on the US satellite images... looks like a classically well-defined hurricane right now.

18z also pimping out hurricane Nigel in his footsteps. Definitely a weenie run for New England.

Sitting outside on the patio. It's a nice 69 degrees. There's a certain bug that I haven't been able to identify. It's not a cricket or cicada, but it buzzes similarly for 30 seconds quickly.

Conehead or Katydid probably. Lots of those buzzing loudly here.

I am confused what is so controversial about agreeing that low 70s and dry is ideal for his trip.   I take it all back.   

[TT-SEA]

00Z GFS and 00Z GEM both show a decent trough dropping into the PNW starting next Monday.   Starting to see some consistency for that period.

[TigerWoodsLibido]

Wildfire smoke is back. Can barely see pisgah and the stars are hazier and can barely see them. Smells like a campfire.

[TT-SEA]

The GFS actually has support from its own ensembles this time as well.   

[TigerWoodsLibido]

Smoke smell is gone at least. 52F and clear out there.

[TT-SEA]

ECMWF is showing a little c-zone rain for King County later tomorrow after the weak trough offshore moves inland.

Found this little fella on the front porch yesterday.

So cute!

Sprinkling here already. Would be a nice surprise if I got 0.2" out of this.

Quote

The Creator would appear as endowed with a passion for stars, on the one hand, and for beetles on the other, for the simple reason that there are nearly 300,000 species of beetle known, and perhaps more, as compared with somewhat less than 9,000 species of birds and a little over 10,000 species of mammals. Beetles are actually more numerous than the species of any other insect order. That kind of thing is characteristic of nature.

I'm a little bummed that it looks like mostly dry troughing, at least initially. I wouldn't be surprised to see the models trend wetter for next week, maybe a quarter of the GEFS members have something early next week. I doubt we escape that pattern change without at least one decent rain.

Not sure how it will play out but the 12Z GFS and 12Z GEM backed off quite a bit from their 00Z runs.

Headed down to SoCal this afternoon, and while I admit I am not familiar with the climate down there other than sunny, high of 80 low of 68 for days on end, the current forecast vs radar loop is "interesting"

 

classic forecast "bust"?

Another park trash can I maintain at work is swarming with yellow jackets.

Can’t wait until all these bastards die a 50 degree drizzly death.

And so you can immediately switch to complaining about 50 degree drizzle?

Medford has 97 forecast on Friday and Saturday, Redding should break 100 on Thursday and could do it Friday and Saturday as well.

Pretty much no cool down on the 12z Euro. Unbelievable we’re heading for another top tier warm month.

The Heat is ON!!!!!!!

[TT-SEA]

SEA is running almost exactly normal for September at +0.1

Currently 73 and partly sunny out here and calm... very pleasant day.

12Z ECMWF still showed rain for King County tomorrow evening....

Yes 

[Phishy Wx]

KGEG is currently +1.7 for Sept to date

[Cascadia_Wx]

12z EPS seems at odds with the operational, showing a faster cooldown beyond day 7. Operational seems to be in lockstep with the control though, for whatever that’s worth. I expect the EPS to trend warmer for longer in coming runs.

[SilverFallsAndrew]

SLE is running +0.4 for the month. I confess I had not checked at all until a few minutes ago. 

[Cold Snap]

Had my 35th 80 degree day yesterday. Looks like I will probably add to that total Friday and Saturday.

SEA NWS posted about this yesterday.    Also interesting that North Bend has had around 60 days at 80+.   I think there was a large number of days that were in the low 80s out here and in the upper 70s in your area.
