Australia Weather: Extreme Heat, Sunday Cold Change, and Next Week's Rain

Extreme Heat Across Australia

• 🌡️ Excessive heat is forecast for Thursday, Friday, and Saturday, with temperatures reaching over 44°C and even 48°C in some inland areas.
• ➡️ The heat will initially move westward and southward into South Australia and Victoria, before shifting northwards by Sunday.
• ☀️ Coastal areas are expected to experience lower temperatures compared to inland regions due to sea breezes.

Significant Cold Change

• ❄️ A colder change is anticipated to arrive on Sunday, bringing a refreshing drop in temperatures to Victoria, southern New South Wales, and large parts of South Australia.
• 🌬️ Tasmania, especially south of Hobart, could experience cold conditions by late Sunday.
• ⬆️ This change will push the extreme heat northwards into northern New South Wales and southern Queensland.

Thunderstorms and Wet Weather

• ⛈️ Thunderstorms are expected in tropical Australia and parts of South Australia, with a line of convergence bringing heavy rain to southern Western Australia.
• 🌧️ Next week, New South Wales and the ACT have a chance of significant rainfall, potentially including proper rain and downpours, especially around the Great Dividing Range.
• 💧 Around the Gulf of Carpentaria and northern Queensland, a low-pressure zone could bring 200 mm of rain in 24 hours by Tuesday, with other inland parts of Queensland seeing 30-40 mm downpours.

Tropical Systems and Winds

• 🌀 A tropical depression near Norfolk Island is being monitored but is likely to dissipate due to high pressure near New Zealand, though it will bring rain and high humidity.
• 💨 Windy conditions are expected in various regions, including south of Tasmania, and due to "squash zones" between high and low-pressure systems, particularly a strong southeasterly in parts of South Australia.
• ⚠️ A 10,000 km belt of low pressure across the tropics (from Western Australia to French Polynesia) is under observation for potential tropical cyclone development, though none are currently expected.
