The well forecast number of 102 degrees was achieved this afternoon at PDX. That makes it the hottest June day in Portland history, and the hottest since the 103 in July 2 years ago. Kudos to Drew Jackson for being right on Friday evening. He had a forecast of 100 & 102 for Sunday-Monday. It ended up at 101 & 102. I think that’s pretty good 2-3 days out!
A weak marine push tonight as gradients are just switching to westerly through the Gorge at 5pm and cool air begins spilling through the Coast Range gaps. I’m a little concerned that the push may be shallow and we only drop 10 degrees tomorrow, instead of the 15 I’m forecasting (a high of 87).
A stronger push tomorrow night gives us brief morning clouds Wednesday and cooler temps.
I really think the big story though is our sudden switch to summer ridging. Most years we don’t get consistently warm & dry weather until after the 4th of July. This year ridging began last week and not a single model has precipitation or cooler than normal temps in the next 7-10 days. Which means "summer" will have started 3-4 weeks earlier this year than last year. More on that on tonight’s weathercast…Mark
