fire and shadow

Yes, a nest of Balrogs has taken over the Pacific NW region.
No? Guess it's another 'heat snap' then. 
Add heat, season with wildfire smoke and simmer. Live with it until you snap.
fires in north-central BC + NNW winds = yuk (yellow tint mine)

This heat was well advertised and anticipated. Models were forecasting 110°, which has never happened this side of a Medford-TheDalles line! The PDX weather folk explained how the 850hPa temperatures occasionally go wild in the models despite other pressure levels appearing typical for a midsummer blast. In this case the 28° Celsius at 850 hasn't happened (yet?) but the arrival of smoke from British Columbia has likely capped the intensity of the insolation.


Salem did measure 25°C (5am reading, yellow highlight) so we are capable of record-setting temperatures, and the Portland airport has set two new daily records. If the smoke clears a bit perhaps the elusive 108° could be achieved.. but forecasts are trending down as the smoke settles in for a few days.

Here on the hill-top we have hit the mid-90s the past two days, not comfortable but not 103 either! The smoky blanket could make tonight pretty miserable though. Portland's thermal blanket kept summertime lows in the mid-upper 60s at times, and we have not missed those nights in the least. However, last night dropped only to 68.7° - warmer than KPDX! - and we may see worse tonight. By late Friday the marine push should arrive, but it is expected to be a weak one that knocks us to the lower 80s by Monday. No rain or serious clouds expected, though an outside chance of thunder as the heat breaks over the weekend.
We shall see..

3Aug: PDX stopped at 105° as of 7PM. We again bottomed out around 67°, warmer than Portland - I guess we are closer to 850MB than they are! According to this site, not much though - and another site suggests we're at 985hPa. Fun facts!
