NSW, QLD: Rain
develops in northern NSW, inland QLD
An upper low that span off a passing Southern Ocean trough on Saturday moved
into far NW NSW today, bringing cold air aloft and generating the surface trough
visible on the chart above. The trough at the surface and the upper circulation
above about 3km have moved significant amounts of moisture across the coast
and into the border area, and the colder upper air arriving from the west moved
instability into the area overnight. Thunderstorms were reported in western
NSW from mid-afternoon yesterday, and rain, only some associated with storms,
began falling in central northern NSW yesterday evening.
The heaviest falls in the 24 hours to 9am were in a north/south band to the
east of Walgett. Rowena recorded 43.6mm, Burren Junction 37.2, Collarenebri
34.0. Showers became more insistent on the North Coast, where Cape Byron recorded
40.4 and South West Rocks near Kempsey 39.2.
During the day, rain continued along the NSW North Coast and developed down
much of the QLD coast south of Townsville. As the upper system moved slowly
east, thunderstorms and rain areas began in southern and central inland QLD.
