NOTE: The Gubler Powdery Mildew Model now active for all Lake County weather stations      
                     
not active - means the criteria necessary to activate the Powdery Mildew Model have not been met yet.    
That is - you must have 3 consecutive days with 6 or more consecutive hours between 70 and 85F.    
If you get 2 days, and then on the 3rd day you get <6 consecutive hours between 70-85F, the model    
resets back to zero and you start all over again.
