Balmy summer-like days are on their way out, with cooler conditions just around the corner. Over the past three days, Adelaide has reached at least 34 degrees, which is well above the March average of 26 degrees, and today’s tops of 35 will make it four-in-a row. Most towns across Victoria will reach 30 degrees or more during Saturday. Across to the Apple Isle, conditions have been several degrees warmer than average, for the past three days. Brisk southerly winds will begin to sweep across the southeast on Sunday. In Adelaide, a gusty cool change will begin to strengthen in the afternoon, and just a few hours later it will arrive in Melbourne. While some parts of the southeast may have a warm Sunday afternoon, everywhere will be significantly cooler by Monday. Cooler conditions will set in just in time for the start of the work week, and look to remain mild until about Friday. Adelaide will drop to the mid 20's, Melbourne and a majority of Tasmania will hover in the low 20's. Unfortunately, this cool change looks to be a fairly dry one, with only southern parts of SA and VIC likely to pick up any rain, and it will only be a few millimetres at best. Central and northern parts of both states will stay dry this week. TAS will see the most rain, with up to 20mm falling to across western parts during the next few days.
