June (July) 2020 Weather Discussion for the PNW

[TT-SEA]

HIO topped out at 90. Seems like that dry Western air finally showed up today as RH dropped to about 20%. As a result it didn’t feel too hot and definitely cooler than yesterday.

 

 

Dewpoints have been around 60 up here.  

[jakeinthevalley]

That would have been my second guess. Daly Lake.

Haven't been to Daly for awhile. Most recently I passed it for Parish Lk. Fishing is better there

[VancouverIslandSouth]

Marine influence increasing... only 71 at SEA while its 80 here.  

 

Ended up hitting 82F here today, still 76F and we're closer to the source of the marine air. It's interesting how it sometimes cools down faster there than here. Dewpoints continue to be higher than normal, maxing out at 64F this afternoon.

RH was about the same as yesterday here, but the high temp was six degrees cooler. I think it mostly felt cooler because today was cooler.

[VancouverIslandSouth]

Fascinating!  

Is this area always warmer? 

 

Yep, possibly the warmest large area of coastal waters on the West Coast north of the Baja in the summer. At other times of the year when there's more mixing it tends to be closer in temperature to areas around it. It can cause some interesting weather like nocturnal convection later in the summer as cool offshore winds on both sides converge over the Strait.

komo is going for 89 on monday and 88 on tuesday ouch

[GeorgeWx]

Better swimming conditions in the Strait of Georgia at around 67F, and certainly a bit warmer than that in the bays and beaches:

 

how does the water get so warm there, slack current?

[Jesse]

Lovely evening out. Down to 78 here.

[VancouverIslandSouth]

how does the water get so warm there, slack current?

 

I think there are a couple factors; it regularly gets moderate north winds in the summer and there are pretty strong tides and currents in places. But it doesn't experience any upwelling, it gets warm water inflow from the Fraser River and it's in a valley surrounded by mountains with few clouds in the summer.

Yikes, the fire season snuck up on us this year: https://www.cbc.ca/news/canada/british-columbia/langford-fire-1.5658284

Looks catastrophic. Prayers going coming your way. BC is in rough shape.

Once the heat misers stop whining for a few days you know it’s just a matter of time before things start spontaneously combusting.

Trying way too hard dude.

 

You just seeth with weather preference anger.

I’m surprised the water of the Fraser would be all that warm. Although I suppose it flows a good distance through the BC interiors which is pretty warm this time of year. I thought it’s ultimate source was glacial though.

[Jesse]

The next 3-4 days look so nice.

[TT-SEA]

Weekend sure looks spectacular.

Yep, it starts up in the glaciers of the Rockies, but it moderates quite a bit through the warm interior valleys. It looks like it averages around 65F near Hope in the summer:

Need rain.

GFS to the rescue?

 

[MossMan]

Down to 59.

[ShawniganLake]

Gfs ensemble looks warm.

Lots of spread.

Beefs up the heat a little bit as well. Nice progression.

Would be nice to see some dynamism.

Did David Lynch hack your account?

Oof..

Might be a good idea to remove the post before this.

[Jesse]

Euro looking very hot next Monday. Could approach 100 down here.

[TigerWoodsLibido]

No warning for our coasts yet.

[Jesse]

Correction:no warning for our coasts yet.

Yet? There hasn’t even been an event that could trigger one. You just saw an old post from the NWS and panicked before even reading the date.

What location and depth is needed to trigger one here?

[Jesse]

What location and depth is needed to trigger one here?

I’m not sure. Probably depends on a lot of factors.

 

I’m probably salty too because I freaked out a little when I read the first post.

[Deweydog]

Considerably stronger than a 7.4.

Well local mets here were making posts about it as if it was fairly serious. A 7.8 MMS EQ is pretty solid.

From what I can tell it is far away from our coastline, out in the Aleutians.

 

And the Richter scale is a logarithmic scale, so a 7.8 is about a thousand times weaker than the one that hit Alaska in 1964, for instance.

Buoys haven't picked up anything significant so like you said, we're probly fine. If an 8+ happened like 50 miles offshore would that be worrisome?

Possibly? Local conditions like tides would probably start to become important.
