Went on a quick chase to near Coraki after MB alerted me to the Grafton cell looking fairly severe. Was able to watch the cell creep up towards Coraki, whilst it still looked marginally severe it was soon to weaken. It had some nice structure at times and there was a fair bit of thunder booming from it. Witnessed some nice CGs and one clear air bolt that was way ahead of the storm. Had a chaser convergence with MB and James Harris as we watched the cell weaken. After 5 weeks of seeing nothing it was nice to hear the rumble of thunder again and witness cloud structure that was something other than Strattocrapulus.
