Notes on the Weather : A Low pressure trough is moving through western Victoria this afternoon, a cold front is developing South of Perth, and tropical moisture resides over the interior of the country. Warm to hot tomorrow throughout, before a cooler SW wind change in the afternoon, spreading eastwards. Patchy rain and isolated thunderstorms will develop and extend across the state with the front.
On Sunday cooler weather returns behind the front, and scattered showers will start to become isolated from the west and contract to Gippsland later on Sunday and into Monday. As a continuation of the pattern, a high pressure ridge moves in and brings fine and warmer weather into next Tuesday and Wednesday. On Wednesday humidity increases again as a low pressure trough develops over NSW, and dips South towards Victoria. Conditions will become unsettled again and showers will extend from the North down over Victoria. Another low pressure trough will approach from the west on Thursday and areas of rain and local thunderstorms will develop throughout from the west. This pattern will be very slow moving so locally heavy rainfall is expected across the state, most likely across the ranges and over the north.
