RAIN was the most important weather event of last Sunday, according to meteorologists.
With 12.2mm of rain in Lismore between 9am Sunday and 9am Monday, the 24-hour period was the wettest day since the long rainy days of June.
Not one day in July, August, September of October so far had that level of rain in Lismore.
Dick Whitaker, chief meteorologist at The Weather Channel, said that "an upper level trough went through the area and caused the instability" we saw last Sunday.
The system went all the way into the Gold Coast in Queensland.
Mr Whitaker said that the system we saw on Sunday could be the first of some storms coming through the Northern Rivers this year.
The hail that covered Goonellabah last Sunday is not included in the levels of rain recorded for the day.
