MossMan Posted March 19, 2019 Report Share Posted March 19, 2019 Those would be new March records at SEA. Absolutely stupendously incredible!! So hard to get record warmth like this these days, we need to really enjoy it when it comes!Indeed!

Phil Posted March 19, 2019 Report Share Posted March 19, 2019 Where exactly the station is sited is key. Near/next to any buildings (with the possible exception of the north side in some cases) is a no go. Near/next to concrete or any heat producing devises like air conditioners, roads/cars, airplanes, vents, etc, is also not viable. Those features cannot even be *in the vicinity* of the sensor. A relatively shady, grassy location away from all infrastructure is really the only way to avoid thermal contamination. And when it comes to comparing modern temperatures to those of the distant past, it possibly cannot be within a city environment, even if the station is well sited. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

GHweatherChris Posted March 19, 2019 Report Share Posted March 19, 2019 Only because of the massive urban development in your area and all the runways built around your house. Today would have been in the 50s without all of that. Yep, and they're putting in another runway here at Central Park International Airport!! Just a mile from my house down by the river. Just look for the van. Quote Link to comment Share on other sites More sharing options...
Phil Posted March 19, 2019 Report Share Posted March 19, 2019 I relocated my temp/humidity sensor from a okayish location (partially shaded area 15 feet from the NE side of our house) to a much better location (shaded area in a spot 50ft lower in elevation away from all buildings) and the result was an ~ 2 degree drop in daytime temps and a whopping 4 degree drop in nighttime temps. I think people underestimate how easy it is for both radiational and anthropogenic contamination to screw with temperature readings. During the day it’s often the former with a little bit of the latter, at night it’s the latter. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...
Jesse Posted March 19, 2019 Report Share Posted March 19, 2019 Mark seems to think that tomorrow will be the warmest day at PDX, with temps in the low to mid 70s. Although with offshore flow dying off and more high to mid level clouds moving in I am picturing something in the 68-70 range again. Quote Link to comment Share on other sites More sharing options...

Pointless though because his goal is to troll and not understand our microclimates.If I move out there after school is done, I’ll set up a high quality weather station, and I’ll do it properly.

I bet its actually in the 40s and hundreds of misplaced sensors around the region are lying to us and saying its much warmer. Also... I bet the early pioneers had sensor placement down to a science and were militant about it. Those old records were never inflated for bad thermometer placement.

Omegaraptor Posted March 19, 2019 Report Share Posted March 19, 2019 We went from an unprecedented extended cold snap with temperatures failing to break 50 for nearly 40 days in a row to parts of Seattle breaking the all time March temperature record.

Phil Posted March 19, 2019 Report Share Posted March 19, 2019 All depends on the strength of the offshore flow. It will be warmer to the west when the flow is really strong like today. Portland experiences the same thing but they get less downslope warming there overall. Or North Bend can be the hot spot in the state with weak offshore flow and downslope warming. And the discussion about downslope warming in the winter is usually related to night time lows. It can be 30 in Olympia and in the 50s here with an east wind. All about exposure to the east wind and mixing and we are very exposed to the east wind out here. You just don't understand our microclimates... and its more fun to say I am completely making it up because I live at 7,000 feet. Omg. You literally told me during the summer last year when SEA had a 10mph SE wind that it was 4 degrees warmer at your house because of downsloping. So increase that by wind by 10mph and somehow SEA gains 8 degrees on you? That doesn’t make any physical sense whatsoever.

And I would never say anything like that about a specific wind speed. There are so many factors involved. Often it can be warmer out here in the summer because we have less marine influence than SEA. Other days it can be warmer at SEA. There are so many variables.

This is the recurring theme here..blanket claims without any counter arguments rooted in the physics and meteorology. The effects of adiabatic heating/drying on the lower boundary layer don’t just cease when the terrain flattens. If SEA and the rest of the downtown areas have a 10mph east wind, and North Bend/terrain areas also have a 10mph easterly wind, there should be little to no cessation in the adiabatic effects, provided the boundary layer depth is relatively uniform. Otherwise it would make no physical sense at all. I’m always open to being convinced/re-educated, but blanket attacks on my character will just increase my skepticism.

The effects of adiabatic heating/drying on the lower boundary layer don’t just cease when the terrain flattens. If SEA has a 10mph E wind and North Bend has a 10mph E wind, there should be little to no cessation in the adiabatic effects in a well mixed profile. That would make no physical sense at all.

Phil Posted March 19, 2019 Report Share Posted March 19, 2019 Phil, you are wrong... let it go man.Again, I’m absolutely open to that possibility, but I want to see quantitative evidence that UHI had zero effect on the readings at SEA/surround areas (which seems almost impossible since there is a well-studied modest effect in all of the I-95 corridor cities, even during high winds, blizzards, and thunderstorm squalls). You can’t just throw science into the trash in place of subjective systems of personal belief. As for the adiabatic warming/drying, that’s a process I’m very familiar with at the molecular level, so unless there are terrain/moisture gradients I’m unaware of out there, or I’ve misinterpreted comments/observations (or am just remembering them incorrectly) I stand by what I said.
