Storms for NSW 6th November 2012 following 126,000 lightning strikes for South Australia

Following the massive lightning show in South Australia yesterday with 126,000 lightning strikes reported on the lightning tracker network, more storms are expected over the coming days beginning from today. Given the amount of heating, there is the chance of storms to once again develop across the inland and perhaps along the coastal strip of NSW today. Some storms may be severe but the most likely scenario will be higher based storms with lightning and strong winds. Some rain will develop across the inland as a meso-low develops. Along the coastal strip, the moist NE winds will pump inland and if they can reach the bases may assist in some development along the ranges from Bombala through to near Sydney.

    I undertook a chase today and after discussing the weather with Jimmy, I proceeded to Goulburn and Marulan to find out what would occur. I did not go any further. At Goulburn, I did some weather checks and soundings and identified that while initial forecasts suggested the region around Wagga Wagga would experience thunderstorms, I found that the dew points were low and thick cloud impacted the area. So far, there have been no storms in that area. At Goulburn, I observed clusters of cumulus clouds forming along a boundary to the east. I drove back to Marulan to observe the cumulus clouds. However thicker cirrus stratus cloud eventually overtook that area which ended any chance of further convection. I also noted how dry the WNW winds were. Around 3 pm, I left after spotting a very isolated shower cell around Mittagong to the north east. I drove towards it and discovered that it was not significant. I returned back to Sydney.

    As I write this a narrow band of light showers are crossing through the Goulburn region but no storms. I found the boundaries and some areas of heating but I noted the dry NW winds did not help and neither did the cloud band further to the west. I observed one cumulus tower approach the congestus stage but that quickly collapsed. I took no photos. At least I did not venture too far from Sydney.

  • Meanwhile in the middle of the country…. there’s been a strong cell on Alice Springs radar moving east ahead of the approaching squall line or bow echo from the SW. It’s still active now at 8pm EDT
