Subject:   Soliciting comments through September 30, 2015 on
           the Experimental Gate Forecast.

Effective August 31, 2015, 1300 Coordinated Universal Time (UTC),
the NWS Aviation Weather Center (AWC) in Kansas City, MO, will
make the experimental Gate Forecast available to users on an
experimental basis in order to solicit feedback. The Gate
Forecast is an online display of a decision algorithm that uses
the High-Resolution Rapid Refresh (HRRR) model to determine
potential thunderstorm activity in a particular terminal arrival
or departure sector.

The product display overlays the sector boundaries on the current
radar loop. The sectors are color-coded with the current gate
status using a three tiered approach:

-Green - no significant weather
-Yellow - some significant weather that might affect some
 portions of the gate
-Red - significant weather that could affect large portions of
 the gate

Around each gate is an icon with the gate name and the forecasts
for the next nine hours. Clicking on the icon will bring up a
dialog box that shows the percent coverage of low and high
thunderstorm probability, the three HRRR runs used in the
forecast and the time of the last update.

The Gate Forecast will be available at:

http://new.aviationweather.gov/trafficflowmgmt/gate

The FAA, pursuant to Title 49 United States Code Section 44720,
established requirements for this weather information and service
which is necessary for the safe and efficient conduct of
operations in the National Airspace System (NAS).
