ACCESS G is suggesting quite a long rain band to travail across parts of the south eastern quadrant of the Australian mainland.
Sunday the 29th Sept
a long trough develops over western Australian interior bringing no rain to inland parts but some patchy rain on the southern WA coast.
As the trough moves eastward a rainband deepens and a closed 994 hPa low develops over Adelaide area giving rain to SA southern parts and s/west and Wimmera in VIC on Monday evening
prime time this could provide quite a strong storm line so look for expert opinion
4am Monday morning
the rainband has intensified and stretches from around woomera to Gippsland. The Mallee should get some needed rain.
Tuesday 10am ACCESS is indicating an intense rain hot spot over eastern suburbs the peninsula of Melbourne and west Gippy . Potentially Up to 50mm!!
That rain band now straddles from s/west Qld through the interior of NSW and through the midriff of VIC. This should provide some welcome top up rain for farmers in NSW and southern QLD
The rest of Tuesday the rainband/trough moves toward the coast.
