Fair enough, but surely the tower can tell you the cloudbase so you know you are going to be able to do the SID visual segment?
Nah they can't.
For a start they don't know what weight you are at and therefore where your visual segment ends, it's a different height on every departure.
Secondly, they have the same mark one eyeball as you so there is little point. Reports from a/c are not suitable as the cloud may be at 1000ft in one part of the basin and at 6000ft in another.
thirdly, the cloud moves quickly, it hugs the hills where you are climbing out and can change in minutes, snow storms or rain moves down the arms of the lake very quickly. It's not a normal environment when compared to most jet rpt airports.
