  • Southerly winds easing over the southeast with cloudy skies continuing

  • Warming up over in the west ahead of a strong cold front.

  • Latest details on the major rainfall event unfolding across the country.

Windy night over coastal NSW and eastern VIC with a deep low rotating through the Tasman Sea. There have been showers hanging offshore most of the evening but another burst is expected to move towards the Central and Hunter coastlines during the coming 24 hours bringing moderate rainfall as a trough moves through.


High pressure moving into the southeast is bringing a cloudy day for southern areas, but more sunshine for inland parts of SA, VIC and NSW with those cold winds easing. The weekend looking and feeling pretty good in this part of the world.


A nice dry surge finally pushing through the northern parts of Australia bringing strong winds and high fire dangers to the Kimberly, Top End and western Cape York with a dry airmass moving through.


Warming up out west with the northwest flow developing and strengthening as a front approaches from the west. Strong to gale force winds developing for the southwest tonight with the approach of that front with showers increasing overnight.


But the big talking point is that major rainfall event spreading from northwest to the southeast, impacting most states in some shape or form next week, we will dive into modelling on that in just a moment.
