Jane Bunn: New cut-off low to drench the southeast this week

A new cut-off low is set to cross the southeast this week:

• Rather than hit and miss thunderstorms, cut-off lows bring rain to everyone in their path

• This path is likely to affect southeast SA, southern NSW, much of VIC and northeast TAS, generally meaning 25-50mm of widespread rain. Over 50mm is possible in southeast NSW and southeast VIC

• Meanwhile, a trough continues to deliver hit and miss storms to Queensland on Monday and Tuesday, with the potential for heavy falls directly underneath a storm. It will then dissipate and be followed by a generally dry break from Wednesday onwards

• The heat in Western Australia contracts inland in the first half of the week but will come back again at the end of the week. This pulse of hot air is likely to cross into eastern AUS in the following week
