SUBJECT:  Solicitation of Comments For Experimental Extended
          Convective Forecast Product (ECFP) Continues until
          November 30, 2011

NOTE: The following changes have no impact on NOAA Weather Wire 
Service subscribers.

On May 1, 2010, The NWS Aviation Weather Center (AWC) in Kansas 
City, Missouri, made available the Experimental Extended 
Convective Forecast Product (ECFP).  Experimental ECFP is 
intended to provide FAA traffic planners and collaborators a 
quick-look forecast of the greatest probability of convection or 
thunderstorms during peak demand times the following day.  
Notice for the initial experimental product comment period was 
confined to regular users of AWC testbed products in order to 
gauge product usefulness and incorporate user suggestions during 
the comment term.  NWS is now accepting comments from all users 
of aviation weather products through November 30, 2011.  To 
complete the survey, go to: 

http://www.weather.gov/survey/nws-survey.php?code=ECFP

The ECFP automated graphical forecast is created from the Short 
Range Ensemble Forecast (SREF) calibrated thunderstorm output. 
Contours are drawn at 40%, 60%, and 80% probability of 
“thunderstorm,” not convection, using CCFP-like contours and 
graphics.  Hashed areas represent 40%-59% probability, solid 
lined areas represent 60%-79% probability, and solid blue filled 
areas represent greater than 80% probability.  The automated 
graphic uses the 09z initialization of the SREF valid for  
18z-00z the next day.
