It would appear that the Bureau Of Meteorology aren’t overly fussed about the chance of storms in the next few days:
Current Weather Situation and Future Developments
A high pressure ridge in the Tasman Sea combined with a low pressure trough over NSW is resulting in a moist east to northeast airstream and unstable conditions with showers and isolated thunderstorms forecast over the local area. This moist airflow and instability is forecast to persist for the next few days with continued shower and isolated thunderstorm activity through to the middle of the week. A ridge of high pressure should bring a return to fine weather towards the end of the week.
Forecast for Monday
A few showers and the chance of a thunderstorm. Mild and partly cloudy with moderate east to northeast winds.
Forecast for Tuesday
A few showers and the chance of a thunderstorm, mainly during the afternoon. Mild and mostly cloudy with moderate east to northeast winds.
Hopefully they are right.
