Key: # = FAST indicates early blight protection most important these days.
     Values based on measured Temperature, Relative Humidity, Wetness, & Rain.
     e = Early = FAST indicates that recent weather was favorable for early 
       blight development but the initial threshold (CD35) was not reached yet.
     W = Wet+Temperature based threshold (CD35) = 35 Cumulative Severity Values 
       for the season.  If inoculum is present,  symptoms are expected soon. 
     T = Tomcast portion of TomFAST indicates early blight protection most 
       important these days.  Values based on measured Temperature & Wetness. 
     * STANDARD SITE: Disease forecast developed from quality on-site
       calibrated environmental measurements.
     ** EXPERIMENTAL SITE: Disease forecast developed from experimental data;
       calibration is in progress.  Forecast is for experimental use only.  
       Compare results for Experimental sites with results from nearby 
       Standard sites before considering information from an Experimental site.
