UPDATE – This page has been removed. On May 18, 2019, wunderground.com turned off the ability to download station data via CSV file, which this script relied on.

A new page has been added to the site that displays historical graphs for PlanoWeather.com – http://www.planoweather.com/wxwugraphs.php. Daily, monthly, and yearly data can be graphed for temperature, humidity, barometric pressure, wind speed, wind direction, precipitation and solar radiation. Data is available back to February 18, 2009, when PlanoWeather.com was born.
