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
FAA’s 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

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
