Radar up until 1975 at some WSOs
I friend of mine who is reading
Warnings brought this photo to my attention and it helps explain why the warning system got so far behind during the Superoutbreak that was going on 46 years ago. It is a photo of the same radar that Joe Audsley was using in 1957 as he went ahead and warned Kansas City of the Ruskin Heights Tornado of May 20, 1957 even though there was a Weather Bureau ban on doing so.
The radar was actually worse than it appears in the photo. This is a time exposure taken with the meteorologist steadying his head against the viewer so that the repeater scope below will look bright. It wasn't. It was terribly hard to read and interpret and, other than the range rings, there were no geographic references.
The radar meteorologist would shout, "Hook at 232° [azimuth] at 31 [nautical miles] while another met would put a "x" or similar notation on a road map covered with clear plastic with a 360° protractor on top of it to try to figure where important storm features were.
While MKC, MIA and other major cities received the WSR-57 in 1959 and 1960, many offices like TUL, DAY, TOP, GLD, etc., were still using the WSR 1's and 3's until the WSR-74C came along in 1975-76. So, when Xenia's supertornado was approaching, this is what the DAY office was using for warning purposes!
Remember, this is just 35 years ago. I know, to some, that seems like a long time but the the very first video games existed before the last of these WWII-era radars were retired.

I can't seem to get the photo to come up. Not sure what I am doing wrong. It can be viewed here:
