Its peculiar and the thing that bothers me is that no model is representing it in any way. The modeled temps all match up well with what is being shown in Franklin, Adams, Central and Southern York, Central and Southern Lancaster, etc....headed for a high today of 83-85. It truly does seem like the people, concrete, and traffic are artificially raising Temps around and slightly to the South of Harrisburg. Its only 81 at my parents house in Valley Green right now. Outside the Harrisburg Metro hot zone apparently.
