Not Always Right But Never In Doubt

I think I'm batting below my weight when I make these kind of long term predictions...but, what the hell. Keep an eye on this weekend for Pine.
GFS for the Grapevine -
Saturday: 17-18k tops; fairly light winds SW to 10K and then SE above that. There should be nice cloud development near 18k with a chance of thunderstorms the farther east you go (Barstow area). *Note: none of the general forecasts are calling for this at this time; just me!
Sunday: 14k tops and west winds.
