Intense heat is sweeping across southeastern Australia this long weekend with temperatures expected to peak in Melbourne on Monday. How will the weather in your state capital fair on Monday?  

The heat is most definitely on for Melbourne for the Australia Day public holiday on Monday. Temperatures are expected to climb to around 42°C during the afternoon. North-westerly winds will bring a blast of hot air from the interior before a cool change makes its way across the city during the evening with a significant temperature drop by as much as 10 to 15°C. There is the chance of a thunderstorm (with little to no rain) just ahead of this cool change. 

• Elsewhere, the state cities will all see temperatures into the 30s with both Brisbane and Sydney topping out at around 31°C. A dry day is expected in Brisbane but with the small chance of a thunderstorm for Sydney. 

• A hot day for Canberra with temperatures into the low or mid 30s and the chance of a thunderstorm.  

• Adelaide and Perth will be sunny with the thermometer reaching 35°C and 32°C respectively.  

• Darwin will see a humid 34°C with the chance of heavy showers or thunderstorms during the afternoon.  

• Last, but not least, Hobart will reach 32°C with the chance of a thunderstorm later in the afternoon.
