For the past hour a feisty (not-so-little) storm has tried to entertain me on the warning desk. At 0440z (3:40pm EDT) the storm initiated NNW of Grafton and decided to remain quasi-stationary. Then it changed its mind and accelerated due north. Then it changed its mind again, and latched onto the Northern Rivers-Northern Tablelands district border before disconnecting by jogging NW. Now it has realised its mistake and moves back E towards the Northern Rivers. All that said, it has remained in the state warning area. My guess - the storm is pushed N by an outflow and spins just a little bit.

The capricious cell earlier has been reorganised into a severe bow echo churning northward just north of Casino/Lismore at 1900 EDT. A weak transient storm-scale circulation passed over Lismore around 6:30pm, but the individual storms are pulsey and are falling short of supercellular.
