• After witnessing the continued decrease of involvement in the SpotterNetwork staff in serving SN members with troubleshooting issues recently, I have unilaterally decided to terminate the relationship between SpotterNetwork's support and Stormtrack. I have witnessed multiple users unable to receive support weeks after initiating help threads on the forum. I find this lack of response from SpotterNetwork officials disappointing and a failure to hold up their end of the agreement that was made years ago, before I took over management of this site. In my opinion, having Stormtrack users sit and wait for so long to receive help on SpotterNetwork issues on the Stormtrack forums reflects poorly not only on SpotterNetwork, but on Stormtrack and (by association) me as well. Since the issue has not been satisfactorily addressed, I no longer wish for the Stormtrack forum to be associated with SpotterNetwork.

    I apologize to those who continue to have issues with the service and continue to see their issues left unaddressed. Please understand that the connection between ST and SN was put in place long before I had any say over it. But now that I am the "captain of this ship," it is within my right (nay, duty) to make adjustments as I see necessary. Ending this relationship is such an adjustment.

    For those who continue to need help, I recommend navigating a web browswer to SpotterNetwork's About page, and seeking the individuals listed on that page for all further inquiries about SpotterNetwork.

    From this moment forward, the SpotterNetwork sub-forum has been hidden/deleted and there will be no assurance that any SpotterNetwork issues brought up in any of Stormtrack's other sub-forums will be addressed. Do not rely on Stormtrack for help with SpotterNetwork issues.

    Sincerely, Jeff D.

Aviation Prog Charts - Precipitation

On the aviation prog charts, areas of precipitation are outlined by solid green lines. The latest surface analysis chart, shown at the beginning of the sequence of prog charts doesn't show the areas of precipitation. http://adds.aviationweather.gov/progs/

FAA/NWS Aviation Weather Services Advisory Circular AC-0045 states: Progression analysis is accomplished by comparing charts of observed conditions to the 12-, 24-, 36-, and 48-hour progs.

It would seem that to see the progression of areas of precipitation, one would want to see it on the latest analysis chart. Does anyone know why it's not shown?

Speculation is that to see current precipitation the FAA wants pilots to refer to more current sources such as METARs.

As far as I can tell, this is not unique to aviation. For example, the HPC's surface analysis charts all omit current precipitation. Your thinking is probably right though--current precipitation is much better depicted by radar, radar summaries, and METARs than a surface analysis. (Which is probably why most surface analysis products that do incorporate precipitation do so by overlaying radar.)

Interestingly, however, the surface analysis chart from one of the only two websites we're allowed to use as a primary source for flight decision-making (strangely, neither of which is aviationweather.gov ... at least for now) actually shows precipitation.
