South Australia, Tasmania, Victoria and New South Wales should all experience a brief spike in fire danger before a colder, rainy change arrives.
Temperatures will reach the the mid-to-high twenties in Tasmania and the low-to-mid thirties elsewhere and humidity will drop to below 20 percent as dry northerly winds gust 30-to-60km/h.
Neither state is facing conditions as bad as during summer but this will most likely be as bad as it gets until next season.
Northerly winds will pick up and dry out ahead of a cold front, causing fire danger to increase early in the week.
Fire danger will be at its highest on Tuesday in SA and Tuesday night and Wednesday in Tasmania, Victoria and western and southern NSW, reaching the very high and severe rating.
Despite weather conditions producing very high and severe fire danger, recent rain will dampen the fire danger potential in some areas. During the past week much of Tasmania, Victoria and NSW has had 10-to-30mm, dampening grass and bushland.
However, parts of SA, western Victoria and far western NSW have had very little additional moisture, gaining less than five millimetres in the past week and this would be a concern.
Thankfully for the whole region, a cooler change with some rain will move through on Tuesday night and Wednesday. There won't be much rain in it, generally less than 10mm but parts of the ranges in Victoria and NSW could pick up more than 30mm.
The rest of the week is looking fairly cool with southerly winds lasting until the following week. Any warming beyond is only likely to be slight, making the risk of severe fire danger very low until late winter or spring.
