The period Wednesday 7th - Monday 12th February 2007 saw some severe
thunderstorms throughout NSW, including a supercell near Lithgow that produced
6cm hail and 113km/h wind gusts at Scone that prompted 55 calls to the local
There were many active storms around Narrabri during the period although only no more than about 20mm of rainfall was recorded on the network of local weather stations throughout the period. Some people out of town reported heavier rainfall.
The first widespread rain occurred on Saturday the 10th when a line of electrically active cells moved in from the west. The RADAR loop to the right (courtesy of the Bureau of Meterology) shows this event. The lightning detector at the Australia Telescope peaked at about 1200 strikes within 56km over a 15 minute interval. The photo sequence left shows a lightning strike from the Culgoora webcam.
Monday the 12th saw some very heavy rainfall just North of Narrabri. This was associated with a squall line that at one stage went all the way from Rowena to Stanthorpe. The Myall Vale weather station recorded 15mm in an hour on this day.
