Hello
Today I had an RDO. I jumped into the car at 11 am and heading towards Windsor, I noted that a large northern storm cell was moving south east. I also noted that the storm cell was beginning to weaken. Further, another smaller storm was developing to the south. I decided to go to Windsor and watch that southern storm develop.
This storm produced several new updraft towers which I photographed. The northern storm weakened further but a new pulse and updraft tower developed on it's southern side. This storm cell was small but produced a rain shaft and some cloud to ground lightning before weakening.
The southern storm consolidated further and after lunch the storm broke. I filmed and photographed a low shelf cloud on its northern side and some cloud to ground lightning.
I experience a burst of moderate to heavy rain, a significant amount of thunder and sustained downdrafts (Outflow winds) at my location. There was no hail.
While the storm was overhead, I watched two new storm cells develop to the east over Sydney. One of these developed over the Epping / Hornsby area and I just made it back into Sydney in time to capture some of its structure on its western side. This storm quickly consolidated, produced some great cloud to ground lightning but became outflow dominant.
A shelf cloud detached itself from the western side of the storm that was blown westwards before disintergrating apart. This storm did not come in from the NW as stated by the media.
It seems that this storm as well as another southern cell developed from the outflow of the earlier storms I had at Windsor. I state this because I experience sustained but cold downdrafts where I was and as this storm was abating and weakening, the Sydney storms were developing as new cells.
I have made an attempt to attach a picture but not sure If I have done it correctly.
