Adelaide is set to endure one more day of scorching weather tomorrow before a cooler, gusty change brings rain and thunderstorms.
After a relatively mild and cloudy day today, it may come as a surprise to some that the South Australian capital is expected to soar to an uncomfortable 36 degrees tomorrow.
As a trough approaches, clearer skies will combine with fresh and gusty northerly winds and a hot air mass to bring a significant spike in the mercury.
The hot and windy conditions as well as a very dry air mass will cause the fire danger to soar, with severe to extreme fire danger expected across large parts of South Australia, including Adelaide.
Thankfully for most, the heat will not last long, as a cool southwesterly change moves through during Wednesday afternoon. The front will be accompanied by showers and possible thunderstorms, with at least 5-10mm likely across Adelaide and its suburbs.
In the wake of the cold front, temperatures are likely to be much more Autumn-like, with the mercury lingering in the low to mid 20's for the remainder of the week. Days should be generally dry until at least the weekend when another cold front brings the risk of showers.
