Good news. I tracked down, like the hunter I am, a WU person. Apparently this is an issue for many other Indianapolis stations.
You are correct, I can not control the timezone nor edit it. Thus it is truncated as
Time Zone: America/Indiana/Indianapol
Which defaults to UTC.
They have a ticket open for both this issue and for elevation editing. I hope this gets resolved soon. He did say it is marked critical. We'll see.
