what's a good site or app for forecasting the weather ~2 weeks in advanced?

Based on my google pHd seems like a system is gonna stall over JH 1/31 to 1/5

+1 for OPENsnow - especially (and only?) since wasatchsnowforecast moved there. For Utah, at least. Pretty good for other areas.

Bergfex was rec'd for Alps - seems good as well.

2 weeks out is general predictions but, like long range surf forecasting, you have to know who to trust - long term experienced forecasters with track record. WasatchSnowForecast is that person.

+1 for Bergfex (Alps only, as far as I know), pretty reliable, last year I used it to plan freeride tours too, thought everything must be taken with a pinch of salt.
