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
KOIN and KGW agree. KATU is going 91, then 90.
What I'm seeing. While median 850s didn't change, too end 850s went up about a degree. Downslope the Euro is going with a 1023 high, to a 1016 low. WRF is doing a 1022 high to a 1014 low. HRRR is a 1025 high to a 1015 low. The Euro didn't change much over 2 days, while WRF and HRRR's gradient went up, without much change in 850s.
Using a modified Temperature potential formula that would better (but not completly) account for this downsloping (aka changing variables in said formula), I come out with a 90 (rounded down) now; instead of 89 (rounded up) just using raw data. Knowing PDX will overperform (and downslope is superadiabatic), I'll jump my forecast to 91 Friday. 89-92 is probably range right now.
Here is for Europe. Overall the trend is pretty similar as an average, -17.9% to -20.4%. We’re lucky that west of the Cascades we have the most positive snowfall trend. No other places have over 100% positive trend. It could be much worse for us, wow just look at England, Denmark and Eastern Europe.
