Subject:  Soliciting Comments through July 27, 2016, on the

          Aviation Weather Center (AWC) Experimental Impacts

          Terminal Aerodrome Forecast (TAF) Board


Effective June 27, 2016, the NWS Aviation Weather Center (AWC) in

Kansas City, MO, will make the experimental Impacts Terminal

Aerodrome Forecast (TAF) Board available to users on an

experimental basis in order to solicit feedback. Comments will be

accepted through July 27, 2016.


The AWC experimental Impacts TAF Board is a time series display

at airports with significant impact on the National Airspace

System (NAS) across the United States that allows the aviation

community to quickly ascertain the specific weather impacts at

key airports across the United States, based on the TAF. Each box

(hourly forecasts from TAF) is color-coded based on the level and

potential impact of weather hazards, while utilizing thresholds

specific to each airport. White represents no impact, yellow

slight impact, orange moderate impact, and red high impact. The

letters in the box represent the cause of the impact, including:

-CIG: Ceiling (hundreds of feet, Above Ground Level [AGL])

-VIS: Visibility (statute miles)

-WX: Weather (see legend)

-WSpd: Wind speed (knots)

-WGust: Wind gusts (knots)


More detailed information can be found for each site by clicking

on the station identifier. This data assists dispatchers and air

traffic managers with flight planning while also raising

situational awareness and improving operational decision making.


The AWC experimental Impacts TAF Board is also meant to

consolidate pre-existing situational displays into a single,

authoritative source. As a result, the following experimental

webpages will be discontinued if the Impacts TAF Board is

operationally implemented:
