hello All…
The USA Extreme’s script on everyone’s left side bar is showing N/A…anyone know the fix or the problem?
Inside the script is this address but when I go there it says this feature has reached it’s end…
http://www.wunderground.com/climate/extremes.asp
Thanks…Chris
Wunderground pulled the plug on the extremes.
Yep, and there appears to be no equivalent in the WU API. So… time to retire that script. I’m not aware of any other source for that data (that we could use).
Correction, I found a NWS site that has the data for high/low temperatures in the USA (but doesn’t have the precip data, so $usaprecip will always return ‘N/A’).
Try this for usaextremes.php

Awesome… Thanks Ken.
Since I seem to have been the one to update this script, I’ve decided to adopt it (awwww…) and give it a home in my script page for NWS miscellaneous scripts. The code has been updated to add a self-downloader and a little comment cleanup, I’ve started numbering this version at 4.00 (so as not to confuse it with Michael’s V3.x version which he his not distributing). This version uses the NWS CPC site and now includes $usaprecip and $reportDate entries in addition to the $usahigh and $usalow values.
Best regards,
Ken
Ken - Thank s a bunch! 
Thanks Ken for taking over this script.
Thanks Ken

Have a small update to the script V4.01 14-Sep-2016 to correct an issue with a malformed data record. Please replace your usaextremes.php script with the update.
