Google Your Zipcode for Weather
A lot of people seem to really like one of the hundreds of variations of weather checking programs. Personally, I hate them because they are [sometimes] a conduit of spyware or advertising popups and suck up resources.
The easy, no frills way I prefer to check the weather is going to Google and searching:
weather [my zip code]
Google then displays today’s forecast plus the next 3 days. This way you don’t have to hassle with annoying programs (yes, I am biased against these) and you can get the information just as quick.
