A massive High is sitting over most of Australia. It will move slowly to the Easy only for another High to take its place. We have a run of cooler and the occasional cloudy days ahead of us for at least the next eight days. Of course this could change as I am only running of the models for Australia. Today could see an odd shower or to pop up.

Next Wednesday a warmer change moves through with temperatures expected to reach 30°+C. GFS is showing some storm activity developing off the NSW Coast later next Friday and well into the night.
There may be a light show for some on the Cold Coast border Region and those in the NE NSW. It is the only signs of activity at this stage. But as it is storm season it one of those things that you need to keep an eye on as it can change quickly.

Below is todays GFS stormcast and lack of anything to see. And also the old faithful 4 day map.

I have also included the possibility of some storm activity developing off the NSW Coast on late next Friday as per the GFS stormcast and other modelling systems.

As we know, it is storm season and even though the models do not pick up changes happening throughout the days ahead, there still can be the chance of storms if atmospheric conditions rapidly change. So please still be vigilant. The models do try and allow for the Chaos factor but they don’t always get it right. The next lot of runs over the next few days could change the whole outcome.

Stay safe and enjoy the beautiful cooler days.
