AS OF TODAY... AFTER VERBAL APPROVAL FROM ALL MEMBERS OF THE
INTERAGENCY JOINT AUTOMATED WEATHER OBSERVATIONS PROGRAM
COUNCIL /JAWOP/ :OF WHICH DR. FRIDAY IS THE NWS MEMBER;...

                   JULY 1... 1996... AT 0800 HOURS UTC

THE DELAY IN THE IMPLEMENTATION FROM THE ORIGINAL JUNE 1 DATE
TO THE NEW JULY 1 DATE IS BASED PRIMARILY UPON DELAYS IN SOFTWARE
CODING AND TESTING THAT OCCURRED AS A RESULT OF THE GOVERNMENT
FURLOUGHS AND SHUTDOWNS THAT TOOK PLACE THIS PAST DECEMBER AND
JANUARY.  THE IMPLEMENTATION TIME OF 0800 HOURS UTC /0400 HOURS
LOCAL DAYLIGHT TIME ON THE EAST COAST AND 0100 HOURS LDT ON THE
WEST COAST/ IS CONSIDERED AN OPTIMAL TIME TO IMPLEMENT BY THE FAA
FROM A SAFETY STANDPOINT.  THE FIRST OF THE MONTH IMPLEMENTATION
WAS MAINTAINED IN ORDER TO ACCOMMODATE THE REQUIREMENTS FOR THE
MONTHLY PUBLICATION OF CLIMATE DATA IN A CONSISTENT FORMAT BY
THE NATIONAL CLIMATIC DATA CENTER.

TO REFLECT THE NEW DATE... AND A WIDER DISTRIBUTION OF THIS
