TO: National Weather Service (NWS) Offices 
           Federal Aviation Administration (FAA)
           Family of Services (FOS) Subscribers

FROM: Cynthia Abelman 
           Chief, Aviation Services Branch
SUBJECT: Changes to Collaborative Convective Forecast 
           Product (CCFP) valid times effective March 1, 2013

NOTE:      The following changes have no impact on NOAA
           Weather Wire Service subscribers
Effective March 1, 2013, 0800 Coordinated Universal Time 
(UTC), the NWS Aviation Weather Center (AWC) in Kansas City, MO,
will cease production of the 2-hour valid Collaborative
Convective Forecast Product (CCFP) and will begin an 8-hour valid
forecast time period.

This change to the valid times of the CCFP is being made in
response to and in collaboration with the changing needs of the
FAAs Strategic National Airspace System planning.  On March 1,
2013, CCFP will change from the valid times of 2 hours, 4 hours,
and 6 hours from issuance time, to 4 hours, 6 hours, and 8 hours
from issuance time.
The CCFP is a forecast of expected convective weather at 4-, 6-, 
and 8-hours after issuance time, produced through a collaborative
process involving NWS meteorologists at the AWC and Center
Weather Service Units, and airline industry meteorologists.  It
is issued every 2 hours.  The CCFP exists as direct support to
the strategic, system-wide planning of FAA Traffic Flow
Management intended to reduce traffic flow disruptions that may
be caused by convective weather.  The CCFP begins March 1 and
runs through October 31 each year, covering the conterminous 48
United States and adjacent coastal waters.
The CCFP is issued as three separate ASCII text files under 
distinct World Meteorological Organization (WMO) headers.
Current issued CCFP WMO Headers: FAUS27 KKCI 2 Hour Forecast 
FAUS28 KKCI 4 Hour Forecast
FAUS29 KKCI 6 Hour Forecast
On March 1, 2013, NWS will cease issuance of the FAUS27 KKCI 2 
hour forecast and begin issuance of the FAUS30 KKCI 8 hour
forecast.  NWS will continue the FAUS28 KKCI 4 hour forecast and
FAUS29 KKCI 6 hour forecast.
Effective March 1, 2013 issued CCFP WMO Headers: FAUS28 KKCI 4 Hour Forecast 
FAUS29 KKCI 6 Hour Forecast
FAUS30 KKCI 8 hour Forecast
