Rain is increasing along the south coast of SA this morning is progressively moving east and northeast today. Some chance of thunderstorms along the leading edge of the rain band where the airmasses are clashing which could top up some of the rainfall totals in isolated pockets, beyond 15mm.
Rain areas will tend to showers over the southern coasts tonight with a clearer day for most of the western and central inland tomorrow as the moisture plume pushes into NSW and QLD.
Still mild inland tomorrow ahead of a stronger cold front on Monday with another burst of showers, with the bulk of the rainfall evolving east of the state with another surge of moisture coming down the spine of the initial trough over the eastern inland of NSW in anticipation of the front rolling through the region during Monday afternoon. So you will see a larger cloud band form there.
Showery weather for coastal areas could be rather productive Monday through Wednesday, especially over the southeast. The weather then improving for inland areas from mid week with high pressure moving east.
GFS 18z - Rainfall for the coming 3 days
The rainfall quite decent for the next 3 days, but really once we get beyond Tuesday, it could be dry for a while with the showery weather clearing the inland and high pressure beginning the next phase of the pattern flip over the nation.
Rainfall over the coming 10 days
The rainfall again is largely expected to fall during the coming 3 days - with the inland tending drier and warmer as we go through the back half of next week into next weekend. So there is a break from the westerly wind barrage in the outlook period.
Rainfall comes into Victoria and NSW this afternoon and this evening, with the chance of thunderstorms about the southwest coast of VIC possible and that may extend inland on the leading edge of rainfall.
Numbers for NSW may be increase further with the second system looking a little slower which could pull in more moisture from the northwest to the southeast - so this could be adjusted this evening.
More weather to come later this afternoon and this evening.
