July 2017 PNW Discussion Thread

[Jesse]

Starting off August at 52 degrees, not bad at all!

Yeah it even dropped to 58 here. Dry air is great.

Live view from Vancouver BC...

 

 

Still not too bad on the Island yet, but the sun light does have a red haze color. We're just on the edge of it, it's visible in the distance on the Rathtrevor beach cam:

Some improvement on the 00Z ECMWF for Portland...

 

 

Already running too cool.

[TT-SEA]

Pretty cool satellite picture of both the smoke in BC and the algae bloom in the Hood Canal.

 

 

Gross to both of those.

 

When was that taken?

[TT-SEA]

Air quality camera on Mt Rainier still shows good visibility... I bet this looks different tomorrow though.

Good! We are heading up there today.

August discussion is now posted everyone.

Departures in the western lowlands generally ended up between +.5 and +1.5, slightly cooler anomalies than June.

 

Overall, the first two months of the JJAS summer season have been warm for the PNW, but nothing extreme like 2015. Very similar to 2013, as has been mentioned.

More like -0.5 to +1.0. Assuming the provisional data is accurate and doesn't change after homogenization.

BLI, SEA, Seattle WFO, OLM, PDX, and EUG all fell in the range I gave (SEA was actually slightly above at +1.6, but we know they have issues). SLE was even warmer, but they seem screwed up lately.

Using all the stations cited in the creation of your map, the numbers I gave are accurate. Unless you disagree with your own map? Can't have it both ways.

You said up to +1, when several of the primary I-5 stations I cited were warmer than that. The map does not disagree with that.

 

Overall, it was a warmer than normal month for the PNW, no doubt about it. Not as warm as June, though.

Nope. I said "generally" up to +1, using the data you cited. It was essentially a normal month on the west side.

 

Still thinking September is cooler than average?

Every single major I-5 station from Medford to Bellingham was above normal, with most in the +.5 to +1.5 range, and some warmer. Silly to dismiss that.

 

I like .5 to -1 for most places in September. Cooler than the rest of the summer for the PNW overall.

2/3rds of the PNW have been generally 2-4F above average for most of the summer. Nothing extreme but definitely a warm summer. A somewhat near average bubble on the west side does not contstitute a "near average" first 60 days for summer for the PNW.

Looks like NASA worldview, the smoke sure looks nasty today: https://worldview.earthdata.nasa.gov/?p=geographic&l=MODIS_Aqua_CorrectedReflectance_TrueColor(hidden),MODIS_Terra_CorrectedReflectance_TrueColor,Reference_Features(hidden),MODIS_Fires_All(hidden),MODIS_Fires_Terra(hidden),MODIS_Fires_Aqua(hidden),Reference_Labels,Coastlines(hidden)&t=2017-08-01&z=3&v=-134.78911635710017,42.06272185819388,-108.89653823210016,57.40842498319388

Seems pretty likely that we will soon be getting into a smoky situation on this side of the mountains with the onshore flow cutting off. It does not take much to limit heating.

Good call.

[Geos]

Month ended up at basically straight normal for my location (+0.05), with only 0.03" of rain.
