Unseasonably warm weather pushing into NSW as airmass moves east

Above average temperatures are continuing today as an unseasonably warm airmass crosses central and eastern parts of Australia.

The warm conditions in the country's south yesterday are as a result of gusty northwesterly winds ahead of a trough and cold front, which was filtering the warm airmass from inland towards the coast.

As this warm airmass continues to move further east, well above average temperatures are also expected for Melbourne and into New South Wales.

In the wake of this frontal system, a much colder airmass will settle over South Australia and Victoria, bringing a period of significantly cooler weather with showers and some gusty winds over the coming days.
