Victoria is enjoying the warm sun today, before rain spreads across much of the state tomorrow. The warm and dry northerlies will continue early on Friday in northern and eastern Victoria before a front and trough surges across the state bringing areas of rain. The South West district will get the rain first on Friday, arriving around sunrise near the coast before spreading east and inland. Melbourne can expect a warm and mostly sunny morning before the system brings rain and cooler southwesterlies from the middle of the day. Rainfall will be heaviest in the South West, with coastal areas such as Portland and Warrnambool looking at gaining 15-30mm. If Warrnambool receives over 13mm it will be its heaviest since spring. The eastern ranges will be the other focus of heavier falls, with isolated totals reaching up to 30mm. The rest of Victoria, including Melbourne, should only see light rain, but it should linger for a sustained period. It should be a damp trip home from work for most people. The only region looking pretty dry is through the Mallee and parts of the Northern Country as the airmass dries out over land. Thankfully for many, the rain will clear off by the start of the weekend across almost all of Victoria as a high pressure ridge takes hold. Temperatures will be much closer to 20 degrees across the state, rather than 30 degrees today. On Sunday there should be a few light showers in Melbourne, but most areas will stay completely dry.
