RPTR IMPLIED THAT THE ASOS ISSUED AN INACCURATE OBSERVATION AND THAT THE NWS PERSONNEL WOULD NOT AUGMENT IT WITH ACTUAL WX CONDITIONS.

Narrative

ASOS ISSUED AN INACCURATE SURFACE OBSERVATION THAT COULD POSE A THREAT TO ACFT. THE NWS PERSONNEL REFUSED TO (AND SAID THAT THEY COULD NOT) AUGMENT THE OBSERVATION. ASOS XX55Z CLR BELOW 120 10+ (NO REMARKS). ACTUAL ESTIMATED WX (I WAS FORMERLY CERTIFIED AS A LAWRS OBSERVER) 30 SCATTERED/BROKEN TCU'S ALQUADS; CUMULO NIMBUS NW-E LIGHT ICING NW-N ASR-9 RADAR INDICATED LEVEL 4/5 TSTMS 7-12 MI FROM ARPT; LEVEL 2/3 RAIN 2 MI NE OF ARPT. THIS SYS HAS BEEN INCORRECT NUMEROUS TIMES DURING THE PAST FEW WKS AND IT IS A SAFETY ISSUE. IT NEEDS TO BE FIXED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THEY WERE TOLD BY NWS PERSONNEL THAT IT WAS NOT THEIR JOB TO AUGMENT THE WX RPT. RPTR STATED THAT THE WX RPT WAS AUGMENTED BY THE NWS 39 MINS AFTER THE HRLY OBSERVATION WAS ISSUED. THE FACILITY MGR DISCUSSED THIS WITH THE NWS OFFICE AND IT WAS UNDERSTOOD THAT NWS PERSONNEL WOULD AUGMENT THE WX RPTS ALTHOUGH THE RPTR SAID THERE IS NOTHING IN WRITING. RPTR ALLEGES THAT NWS PERSONNEL DO NOT INITIATE AUGMENTATION OF THE WX AND HAVE TO BE TOLD BY TWR PERSONNEL OF THE ASOS WX DISCREPANCY TO GET IT ACCOMPLISHED.
