Ivo, can you add a Thermal Base button for the Soaring and Gliding communities?
Super easy to calculate if you wish to go simple.
Thermal Base = 1,000 ft per 4.4F° difference in surfacetemp - dewpoint
(there are more complex formulas but this is good enough, this usually also forecasts the cumulus layer cloud base).
Thank you for a most awesome site! - Michael Price
