Everything still on track for a very hot day today…upper atmosphere has warmed a bit, plus offshore flow is still lingering over the Cascades. That easterly wind is much weaker this morning, so a widespread easterly wind is not in the cards for the metro area, but the effect will still be there to maximize heating. I notice Corbett was the warm spot last night…it didn’t get below 70 degrees last night with the wind keeping the air stirred up. That’s quite a turnaround considering a few days ago they had a tough time even getting ABOVE 60 degrees for a high!
A few obvious changes today will make it feel hotter: lack of wind for one, and then take a look at the picture above. Low clouds have pushed inland as far as the Longview/Kelso areas. That with the loss of the dry wind from the east means signficantly higher dewpoints; it’s going to be more humid.
You can see some thunderstorm leftovers in the South Oregon Cascades…I doubt that moisture makes it farther north than the Three Sisters today…but some good action down around Crater Lake!
