The 2 Notice errata are caused by your language-en.js file which has
var langHeatWords = new Array ( /* used for Heat Color Word */
'Unknown', 'Extreme Heat Danger', 'Heat Danger', 'Extreme Heat Caution', 'Extremely Hot', 'Uncomfortably Hot',
'Hot', 'Warm', 'Comfortable', 'Chilly', 'Cool', 'Cold', 'Very Cold', 'Extremely Cold', 'Dangerously Cold', 'Extreme Cold Danger' );
which has more entries than the standard one in ajaxWDwx.js of var langHeatWords = new Array (
'Unknown', 'Extreme Heat Danger', 'Heat Danger', 'Extreme Heat Caution', 'Extremely Hot', 'Uncomfortably Hot',
'Hot', 'Warm', 'Comfortable', 'Cool', 'Cold', 'Uncomfortably Cold', 'Very Cold', 'Extreme Cold' );
Those extra 2 entries used by ajaxWDwx3.js for the alternative dashboard are what is causing the messages in common.php.
The WU-radar scripts have been discontinued as WU stopped publishing the radar images and maps used by the script.
Replace wxradar.php with one from the Base-USA.zip distribution.
