At Mark's request, I've redone the usaextremes.php script from relayweather to use WeatherUnderground as the source for the data.
Here's the code for usaextremes.php <?php
############################################################################
#
# Project: USA Extremes
# Module: usaextremes.php
# Purpose: Provides USA Extremes for Web page display
# Authors: Michael (michael@relayweather.com)
# Ken True (webmaster@saratoga-weather.org) V2.01
############################################################################
# Usage: Place the following on your webpage
# CHMOD 666 for cacheFile2.php
# include_once('usaextremes.php');
#
# Then call the following tags within the page where you would like them displayed:
# $usahigh
# $usalow
# $usaprecip
#
# Note: allow_url_fopen = on
# in your php.ini is required to run this script.

After installing, you may need to run it with ?force=1 to clear the cache and reload the page from Wunderground.
Let me know how it works for you...
