Gorgeous sunset from Mt Tabor park. Lots of big, downed trees on the north and east side of the park from our ARCTIC WINDS three weeks ago. But honestly the damage wasn’t quite as bad as I feared. I guess the historic shelter took a pretty good hit but that part of the park was cordoned off.
I was intrigued so I looked up the average high and low temperatures across WA for August of 1899. Olga's average low of 45F is pretty impressive as it's about 4 degrees colder than anything we've seen in the last 50 years. The fact it's so much colder than every other location on the west side does make me wonder if there was an error with the thermometer at that time or maybe it was just incredible cold winds blowing off the straight.
The Seattle average high for the month was almost 10 d
So for this Friday, based on models, the 850 temps appear to be around a +16. This is the lowest I'd like to see for a 90F+ in Portland (+15 can be acceptable if there is ample downslope winds. Temperature potential is 89 given a 1020 mb pressure (what said models are forecasting). However, downslope winds are expected which may make the true temperature potential higher. I'm still going to stick with 89 for now, though the true potential is at 92-94 (depending on wind speed) if 850s don't change.
May 28th, 1983 stayed below temperature potential (107F), and June 2021 at Salem already was cooling down at the highest 850s at sounding time, though the day before was a +0.2F above potential. If I had to guess, the 30.4C 850s weren't the highest at sounding time compared to earlier that day.
