The first set of charts to the right are from the NWS four-panel prog chart 2038 that told me two days in advance (Thursday) of the aproaching “Long Jump conditions.” I shaded in what I considered to be the calm part of the surface high at take off time.
I also marked on the 700 mb chart (10,000 feet), the location of the surface high, the wind speed in knots where I expected to take off and where, by deduction, I expected to land.
The second set of charts to the right are from the NWS four-panel prog chart 2046 for two hours before the take off. On the surface chart I marked the location forcecast for the surface high at 1 hour after landing. On the 700 mb chart I marked the forecast locations of the surface high at take off and landing, and a proposed take off location and resulting flight track.
I received both the 2046 (36 hour prog chart) and 2047 (48 hour prog chart) on Friday to confirm the planned launch, flight path, and landing areas. The flight is scheduled for Saturday morning.
The third set of charts to the right are from the NWS four-panel prog chart 2047 for one hour after landing. On the 700 mb chart I made the same markings as on the 700 mb chart for take off time. Both showed a flight towards western Kentucky, where I expected to land, and onwards to southeastern Tennessee, where I did land.
The important message here is that these are easy-to-read pictures. I hope the reader can see how I read them and that I went exactly where these pictures showed I would. I’m near-sighted, so I can take my glasses off and see everything on these charts, but anyone can use a good magnifying glass to see everything there. And those who have access to an enlarging photocopier can simply enlarge them and at the same time increase the contrast.
