Hack the Weather Widget
John Gruber of Daring Fireball fame has put together a step by step walk through of his recent hacking of Tiger's Weather Widget. He was tired of checking the weather and not knowing if the information had been updated recently or not. So, he hacked it. Here's the 411: "I moved todays predicted high and low temperatures together, above the name of the city.... Underneath the city name, I display the time of the last data sync. So, if the time displayed in my hacked Weather widget is close to now, I know the data is fresh, and theres no need to wait. If time is more than an hour ago, I know I need to wait."
If you would like to do the same to your Weather Widget, head on over and check out the full instructions. I'd like this more if it had a button that I could click that would immediately refresh the data. If anybody has the time to hack that together, post the code in the comments and I'll add it here.
