High pressure will dominate the southeast of the country for the rest of the week, ensuring another stretch of dry weather. Days will be warm and sunny, and cold nights are likely - but there is the risk of an inversion, keeping some alpine temperatures above zero overnight (as we are under high pressure). The centre of the high is overhead by Thursday morning, and to our east on Friday.
A cold front will cross southwest Western Australia on Thursday, then form a cut-off low as it crosses the Bight on Friday and Saturday. This low is set to wander across Victoria and southern New South Wales, affecting alpine areas on Sunday and Monday.
The air pressure is still quite high (limiting precipitation) but there is a cut-off low (encouraging precipitation). A cold pool (the driver of this system) should help deliver snow, but I would expect it to be only up high, as the system will start off warm.
The rain/snow mix continues with the low on Monday, with the potential for 20cm (total) up high.
High pressure once again dominates from Tuesday.
