Yes, for the homepage with ajax-dashboard6.php. This is due to some issues with the inclusion of images that are too wide for the actual area alotted so the browser tries to 'make it all fit' as best it can. If you look at other pages in your site, they fit the 800px narrow setting just fine.
You'll need to tweak the image sizes for the included images (radar map under forecast should be 230px wide specified) and maybe reduce the width of the blitzortung map.
Your cloud-base.php has two errata :
Deprecated: Implicit conversion from float 46.5 to int loses precision in /home/mcdconcepts/public_html/cloud-base.php on line 987
Warning: Trying to access array offset on value of type null in /home/mcdconcepts/public_html/cloud-base.php on line 1005
and those are preventing display of the cloud-base image.
Also, there may be an unclosed table or div as the row with the blitzortung map shows an extra (blank) cell on the right, and that shouldn't be there.
