CHIEF...CLIMATE SERVICES DIVISION
SUBJECT CURRENTLY SOLICITING PUBLIC COMMENTS BY JUNE 30 2003 ON
PROPOSED PLANS FOR MEDIUM RANGE CLIMATE OUTLOOKS AFTER
OCTOBER 1 2003
WE ARE SOLICITING COMMENTS BY JUNE 30 2003 ON PLANS FOR SERVICE
CHANGES TO TAKE PLACE AFTER OCTOBER 1 2003 IN THE CLIMATE
PREDICTIONS CENTER/S /CPC/ NATIONAL MEDIUM RANGE CLIMATE OUTLOOKS
/SEE CONTACT INFORMATION BELOW/. SPECIFICALLY...WE ARE PROPOSING
TO DISCONTINUE 6- TO 10-DAY OUTLOOK PRODUCTS /LISTED BELOW AT THE
END OF THIS MESSAGE/.
THESE CHANGES WOULD ELIMINATE SERVICE DUPLICATION AND POTENTIAL
INCONSISTENCIES SINCE THE 6- TO 10-DAY OUTLOOKS OVERLAP THE DAY 6
AND DAY 7 LOCAL FORECASTS ISSUED BY THE WEATHER FORECAST OFFICES
/WFO/ AND DAY 6 AND DAY 7 NATIONAL FORECASTS ISSUED BY THE
HYDROMETEOROLOGICAL PREDICTION CENTER /HPC/. CPC PRODUCES
NATIONAL WEEK TWO FORECASTS THAT WERE DESIGNED TO REPLACE THE 6-
TO 10-DAY OUTLOOKS WHEN THE WFOS AND HPC BEGAN MAKING FORECASTS
FOR DAYS 6 AND 7.
THESE CHANGES WOULD ALLOW CPC TO CONCENTRATE MORE EFFORT ON
IMPROVING THE SKILL OF THE CORRESPONDING WEEK 2 OUTLOOKS AND
FUTURE INTRASEASONAL OUTLOOK PRODUCTS.
BEFORE MAKING THESE CHANGES...WE WILL WORK WITH YOU TO ENSURE
THAT HPC/S AND THE WFO DAY 6 AND 7 FORECASTS AND CPC/S WEEK TWO
OUTLOOKS WILL MEET YOUR FORECAST NEEDS FROM DAYS 6 TO 14 THROUGH
A SMOOTH TRANSITION AND SUFFICIENT ADVANCE NOTICE.
