Anyone interested in plots showing model wave predictions for this day
for the northern half of Gordon's flight can check out the plan view
at 500 mb (around 18,000 ft MSL) for 1300 PST at

and a corresponding vertical cross-section along the diagonal dashed
line in the above plot (parallel to the wind) at

These are for a horizontal resolution of 4km, about the largest
possible grid size to show such waves. Plots at other times, heights,
etc. -- including plots at 1.3km resolution over a smaller domain at
1300 PST -- can use links at

(BTW the "RAS" in the RASP acronym has nothing to do with this
newsgroup!)
