TWY612, MRY to OAK: no forecast yet

It's too early to give you a forecast. I don't yet know the flight plan for this leg of TWY612, so I can't give you an accurate forecast right now. Come check again closer to departure time. (Note that sometimes I don't know the flight plan until minutes before boarding!)
