A few years ago I used to use this "weather watcher live" program for a taskbar temperature. At that time, it was limited to NWS stations. However, last night I ran upon it and noticed it now includes personal weather stations! It's not free however. I believe the subscription is $19 for a year which isn't much at at all. It's a nice way to have your local PWS temp in your task bar if you're on a computer that's not directly connected to your weather station software. You can choose to get your PWS data from either Weather Underground or Weather Bug.
It has a 30 trial
