I have never gotten this widget to work either until reading everyone's responses here. This is what I found:
1. Widget seems stuck on Heavenly and reports that it has nothing to report.
2. Flip it over using the 'i' in the bottom righthand corner.
3. Enter any resort that isn't the one already in the search box.
4. When you hit the Return key, you'll see a quick flash of text underneath stating "Validating..."
5. If it has found a valid resort, it will fill in the field with the name.
6. Flip the widget back over (Hit "Done") and the latest data for that resort should display.
7. Flip it back over and enter the name of the resort you *really* want to know about, it should validate and when you flip it over it will display the info you were looking for.
For example, I wanted to know about conditions at Kirkwood but it just showed Heavenly in the title and no conditions even if I flipped the widget over and saw that "Kirkwood, CA, USA" was in the search field. So, per one of the suggestions above, I entered "Taos". That seemed to goose it into action and I got the latest conditions at Taos. Flipped it back, re-entered Kirkwood and it worked that time.
