A long wave ridge has been allowing heat to build across Australia’s interior.
Parts of Western Australia and South Australia saw high maximums in the last two days.
Eucla boiled with a top of 40 degrees yesterday, 14 above average and their hottest day since February last year.
Adelaide peaked at 37 degrees yesterday, which is eight above average. Interestingly, the day before Adelaide had its coldest morning this month with a minimum of 13 degrees.
A trough and approaching front dragged in hot northerly winds from the interior, causing the high temperatures.
South-easterly winds are currently bringing cooler temperatures to Adelaide and the main heat should stay northwest of the city until Saturday 22nd.
On Sunday 23rd westerly winds shall bring heat further south and allow the city to again reach into the low thirties.
The monsoon should weaken over the coming weeks, which is likely to allow further heating over the interior.
