Pacific Northwest Weather - May 2023

Correct me if I’m wrong, but people often live in/move to SoCal because they don’t want distinct seasons, right?

But there are distinct seasons. Coolest part of the year has highs in the mid to upper 60s and lows in the 40s. Warmest part of the year has highs in the mid 80s and lows in the mid 60s. 

So far we are still having highs in the mid 60s which feels even colder than our winter since most of the days are sunny in January. 

May Gray usually comes in cycles with some cloudy days and some sunny days once it burns off. This year it's all cloudy days. Endless troughing with no sign of abating any time in the foreseeable future. 

I think someone must have asked Santa for Seattle and Los Angeles to switch climates last Christmas.

This is why west is best.

Also seems pretty silly.   What defines "too hot"?

It looks to me like that ridge is going to try to retrograde right into the PNW. A decent chunk of the ensemble members now have a PNW heatwave in the ~June 4-9 timeframe. Far from locked in, but more likely than not IMO. 

It will. Or at least up into W/NW Canada. Should be the grand finale to the subseasonal warm/dry regime that began during the 2nd half of April.

Thereafter it looks relatively tame until late July, at which point there is room in the pattern for the return of heat spikes. But unlike the last 2 years it won’t come via the 4CH route, rather will likely be centered in W-Canada and the spikes should be relatively transient in PNW region. The farther south you are on the west coast, the more transient it will be thanks to ULL/STJ influence (imo).

I wouldn’t consider a 15°F variation in averages as distinct seasonality. Not even close.

I think mid to late June might be decently wet though with the northward movement of the jet extension.   Hopefully that is the case.    It would not be good to go into July and August without a couple good soaking rains.

A rainy jet extension in late June?  I’ll believe it when I see it.  I’d normally think of a stagnant ULL pattern to produce much rain that time of year.

Should I respond with “It’s coming, get your snow tires on now!” ?

Taking some time off since my kids from Oklahoma are out for a couple of weeks. Burning piles of Scotch Broom today. Looks like it could be a limited burning window this year.

Nah, not really. They watch it for a few minutes and then go back inside or play with the dogs.

@TT-SEA what do the Euro cloud maps show for the timing of clearing in our area tomorrow and Sunday? Want to time our time on the lake accordingly!

What lake?   Timing depends on location.   Tomorrow never does fully clear in the central Sound area (i.e. King County) per the ECMWF.   On Sunday it looks basically sunny after 1 p.m.

Here is 5 p.m. tomorrow:

We had a nice transient jet extension at the end of June 2002 in an otherwise dry summer. Great Nino winter followed.

Not sure of the upper level details... but out here we had a month long dry spell from mid May through mid June in 2009 and then picked up 1.75 inches of rain in North Bend from June 19-22.     Also a developing Nino year.

Not sure what to make of tomorrow.    Suspect reality will be broken clouds because the ECMWF also shows temps into the low 70s in King County and its been running 4-6 degrees too cool as usual.   So if it's really in the mid 70s tomorrow then that implies a decent amount of sun breaking through.

Think that was more of a ULL setup. I remember some good convective downpours with it.

Yeah, it’s hard to imagine an above normal high without any sun this time of year. Although I do remember a July 4 a few years back that almost hit 90 under total overcast. Totally different pattern though. I think that was 2018.

Currently 81.1 after a low of 50. Tons of cotton blowing everywhere. One of my friends who lives out in bellevue managed to get a nice dusting of it. 😂 Must be a lot of cottonwood trees by where he lives.

Anecdotally... I clearly remember the cottonwood explosion in 2009 because my in-laws were in town for my wife's birthday and they were commenting on how it looked like snow.   It's happening about 10 days later this year.   Seems like it's usually a mid May thing.

Worth noting... the 18Z ECMWF came in significantly more cloudy and about 5 degrees cooler for tomorrow than it's 12Z run.
