"Monday and Tuesday are set to be mostly fine with overcast skies and odd showers coming and going over the days but they are also set to be quite warm days with temperatures between 24C and 25C."
But he says as things head into Wednesday it is a completely different picture.
"Wednesday looks like it is the most miserable of the lot," he said.
"We are expecting heavy showers at times and temperatures to drop with highs of only 18C late Tuesday and continuing into Wednesday."
The heavy rain and cool temperatures are set to be the aftermath of Tropical Cyclone Gretel which will make its way towards the East Coast from New Caledonia late Tuesday.
It isn't expected to hang around for long though with Thursday ready to change its tune with mostly fine conditions and temperatures to creep back up into the low twenties.
It looks ready to gear up for a potentially sunny weekend again next weekend.
