Isolated Supercell Advances Through the Northern Rivers: Thursday 14th December 2006
by Michael Bath
Some valley fog at first. Very warm to hot and mostly sunny with fresh northerly winds. Some altocumulus and cumulus about. A supercell thunderstorm developed south of Grafton about 1pm and tracked to just south of Lismore before dissipating about 5.30pm.
Spectacular features and lightning on its approach with very obvious base rotation observed at McKees Hill while on chase.
Other weaker cells eventually developed close to the supercell and eventually cut off its energy. Clear by evening.
