The tower at BVI continues to improperly send METAR report via Aeronautical Information System Replacement (AISR) as required. This is the only way the weather report for this training airport gets into the system for preflight planning applications and sites. The AWOS 3P is not connected for auto processing. Therefore when the tower is closed or the weather is not processed correctly by the tower it affects TAF forecasting. This has resulted in two of our students encountering unforecasted weather. One student pilot came up on IMC weather; landed at another airport [which is] a serious safety issue; but the right choice. Discussions with both the tower manager about the processing issue when the tower is open and with the airport manager about AWOS 3P connectivity have not improved or corrected the problem. I discussed with the local NWS office the effect of not having the current METAR on the TAF amendments. They stated it resulted in limited forecasting and delayed amendments. This is a serious safety hazard for this airport and training environment.
GA instructor reported improper BVI METAR weather dissemination via AISR. Instructor reported AWOS 3P is not auto processing and measures to correct this have not resolved the issue.
