We noted for years now that upper level clouds can play havoc with
a soaring forecast. Yesterday the forecast was for good lift and a cumulus cloud
base between 4000' and 5000'. But at about 12:30 a deck of high clouds came over
casting shadows and lasting until about 2:00 PM. It was clear after that with a
sky full of cumulus clouds and light winds.

None the less the weak conditions discouraged us from attempting aviation until
Wednesday.
