Subject:   Removal of the Experimental Aviation Summer Weather
           Dashboard effective October 30, 2014

Amended to change removal date to October 30, 2014

NWS will eliminate the Experimental Summer Weather Dashboard
October 30, 2014. The Experimental Aviation Summer Weather
Dashboard (AWSD) depicts the potential of convective weather
impact to the Core 30 (minus Honolulu) airports. The AWSD,
updated four times per day, shows the potential impact to each
airspace through a matrix of color coded boxes that depict
nominal (green), slight (yellow), moderate (orange), and high
(red) likelihood of occurrence out through a Day 2 forecast. The
probabilistic information is calculated using the Short-Range
Ensemble Forecast (SREF) numerical weather prediction system.

The ASWD was developed to support the Federal Aviation
Administration Air Traffic Control System Command Center to
coordinate long range strategic summer weather planning by
providing guidance on the impact from weather at major airports.

The Experimental Aviation Summer Weather Dashboard will only be
available at:

  http://testbed.aviationweather.gov/summerdashboard/

Feedback on the experimental ASWD indicated NWS needs to
complete
additional developmental work to support the intended use of
this
decision support guidance.
