This comes from the U.S. Weather Bureau which is now known as the National Weather Service. The data indicates the wind shifting (in Portland) from out of the southeast to out of the west to out of the south-southwest over the course of 2 or 3 hours.Here is the post along with the link. At no point did I claim that they were winds aloft, yet you fail to recognize that Tom's winds aloft data was from GROUND to 12,000 feet.

Chaucer, Tom Kaye's "winds aloft data was from GROUND to 12,000 feet" is exactly what I have been telling you. The NOAA balloon data was the sole source of measured data used in predicting the winds aloft that the FAA issued for pilot planning purposes. Except for the measured NOAA balloon data and what was measured at ground level and reported in the hourly sequences reports, everything else was a prediction.
The winds aloft were measured by the balloons from ground level up and we do not need to go above 10,000 feet above sea level here since that is as high as the airliner went in the WA and OR areas.
