USA Today website has best forecast for Somerset, PA
 

Weather.com forecasts showers on Saturday, CNN.com has thunderstorms, but USAToday.com has just mostly cloudy! Highs in low 60s.

that would be "most optimistic"...we won't know if it's "best" until after the fact. :-)

Jees, you caught me, and I'm a journalism major! mea culpa...
 

Or perhaps it is the "best" forecast for us optomistic types!
