Nice that this came through the appropriate channels, ie, from FAA to contractor to weather observing stations. Typical FAA.

and it did not incorporate the changes from the new FMH-1. or correct errors previously pointed out numerous times in the past. I thought these two manuals were supposed to "complement" each other...

Well, we wouldn't know it by looking at it, but the 7900 is supposed to be derived from the FMH-1, meaning the 7900 cannot contradict in any way the main governing manual on weather observation (FMH-1). So the 7900 is now way behind in being up to date, even though it was just "updated" as well fairly recently. The FAA should have the 7900 caught up by about 2025 or so.....

Just more ignorant arrogance from our good buddies... trying to force us into irrelevance.  How many people have to die before the FAA & Joe in particular figure out stand alone robot ASLOP and/or distracted ATCs are REALLY dangerous? (I expect they actually have a number for that ... Meantime, they want us to lobby for more money for them so they can keep us afloat... they really don't like continuing resolutions. |

Have there been any updates to this in the 7900.5D...
10.29. Beginning and/or Ending of a Thunderstorm. A thunderstorm is considered to begin at the station when thunder is heard, overhead lightning is observed and the local noise level is such as might prevent hearing thunder, or lightning is detected by an automated sensor within 10 miles of the airport. A thunderstorm is considered to have ended 15 minutes after the last occurrence of any of the above criteria. When the time of beginning or ending of a thunderstorm is reported in the remarks section of a SPECI observation, it need not be reported again until the next transmitted METAR observation if not previously reported in a METAR observation. If previously reported in a METAR observation, the time need not be reported again.

I think it's self explanatory...a thunderstorm is considered to be at the station when...thunder is heard (WEATHER OBSERVERS) or lightning is detected by an automated sensor (ALDARS) within 10 miles of the airport.
If this is the case...VCTS should not be reported...I also reviewed an e-mail from Kenny which states that VCTS can be changed to TS if thunder is heard.
Your thoughts...
