Australia is only a little way into the storm season and already severe storms are on the way, with Melbourne in the firing line of a battering. A fast-moving cold front is poised to sweep into Victoria and Tasmania tomorrow, causing thunderstorms to fire up in the areas ahead of it. The Western and Wimmera districts should be affected first, with storms perhaps even popping up as early as 8am. As the day progresses, the storms should become more frequent and widespread. Plenty of moisture will filter in ahead of the front, and instability will be deep, both factors that indicate heavy rain and flash flooding could occur. Melbourne will be a sitting duck as the front approaches, with northwesterly winds driving in showers and storms from the higher ground. Storms are likeliest during early afternoon, but could occur anywhere from 10am to 3pm. Behind the front, winds will be very gusty and much cooler, delivering showers during the evening. All in all, residents of central Victoria should be prepared for a wild day. Keep checking weatherzone.com.au for the latest forecasts.
