Heat spreading across southeastern and eastern Australia
The hottest conditions seen so far this spring will affect parts of South Australia, Victoria, New...
The next two days are set to see the mercury rise across much of South Australia, with Thursday likely to see the hottest temperatures, coupled with fire weather and thunderstorms as a cold front sweeps across the state.
A low pressure trough coming in from the west is causing warmer northerly winds to push across the state. While today was warm, tomorrow is set to be even warmer as the hottest part of the airmass begins to enter South Australia.
Adelaide will push into the mid 30s for the first day this spring, whilst those of the far west and north will see temperatures pushing into the mid-to-high 30s. Thankfully, winds are expected to be light tomorrow, so fire weather is not expected to be bad, although the airmass across the state will be dry.
On Thursday, temperatures will soar as northerly winds strengthen and become gusty, with many parts of the state reaching the mid-to-high 30s, and some locations even reaching into the low 40s.
Unfortunately, dry northwesterly winds are expected to be fresh to strong and gusty at times, enhancing the risk of bushfires. A squally southwesterly change is also expected to accompany the front, which will make it difficult for firefighters as they potentially deal with a rapid change in the directions of fires..
Thunderstorms are also expected with the change, mainly over western and northern areas. These thunderstorms are expected to contain little if any rain, further enhancing the risk of lightning starting bushfires. The hot conditions coupled with the dry air will also increase the chance of dry microbursts with any thunderstorms.
The cool change will have moved through much of SA by Friday, bringing cooler conditions, particularly across the south. Adelaide is expected to only reach the high teens from Friday and throughout the weekend in the wake of the change, before warming up again next week.
