I own a personal weather station. There are many weather observers who have their own stations, and mine
is online just as many of the other are.
My station is solar-powered and wireless, and it updates every five minutes.
There is a terrific free app called PWS Monitor with which you can monitor a station in your area
if there is one. For my Blue Quill station, after downloading and installing the app to your ipad or iphone,
search for IALBERTA572, or Edmonton Blue Quill.
It's a nifty way to keep track of weather in your immediate area.

For your computer, my station data is at http://www.weatherlink.com/user/tvnewsman/
