Light-Sport Aircraft Yahoo group Lifted index, was: Maxpro Battery monitor

Bill,

There are several web sites that list the soaring lift index/soaring index/thermal index.
Most seem to be related to a specific area.
Here is a lifted index that covers the U.S.
I'm not sure this will be of any help.

Mostly, using the Williams...pdf, I compare the current clouds with the pictures to get an indication of the stability/instability of the air.
