I've never heard of Lee's problems, but I think it's a good idea to keep
the high-level clouds because they prove that we can do them, and they
make the sky look vaguely realistic (how often do you get clear skies in
San Fransisco? Simply off the geography, I'd guess not too frequently,
but I've never been within 5000 miles, so I don't know)

I mentioned once that I was seeing some strange jumps in the wind and 
visibility when I take off (from near 0ft alt airfields) and not using
weather - I wonder if some of the problems that some newbies experience
also be due to this.  For example, sometimes I'm getting 6kt winds at
level, when they should be 3kt and then quite often they're up to 30kt
by the 
time I'm up to around 800ft agl.

It doesn't seem to happen consistently but I'd guess it occurs about 50%
the time.  Re-applying the weather settings via the gui will eventually
it out but frequently, after re-applying the settings by clicking the
button, and then clicking 'OK', the weather reverts back to the
settings.  Sometime clicking the 'Apply' button has no immediate effect
and I 
have to click it many times before a change occurs and even then, it's
always to the correct settings.

Just to confirm, I've been checking the settings in /environment via the

property browser and I can see there that the settings are incorrect.

If this were to occur to a newbie I can easily imagine them having
keeping the C-172 level as they transition from 6kt winds in one
direction to 
30kt winds from a different direction, and when it does occur the
is pretty sharp.

Apart from some modifications to the visibility ranges I'm using the
default weather settings.

I haven't tried zeroing all the settings yet, to see what effect that

Re the clouds, I think it would be a good idea to keep the high-level
cirrus - 
that's unlikely to cause any problems with a first time user and does
up the sky a bit.
