WA's sizzling south

Across southern parts of Western Australia, residents are baking in what feels like an early start to summer.
Sunscreen tubes have been emptying quickly. In fact, Perth and Kalgoorlie had its hottest week this early in the season on record. Albany, Northham and Narrogin both haven't felt a week this warm so early in the season in over 100 years.
This heat comes after a warmer and drier than average September in southwest WA, which further contributed to long-term rainfall deficiencies in the area.
A dominant easterly wind direction and cooler-than-average waters off the Kimberley coast have contributed to cloudless days over the Pilbara region of WA in late September, allowing hot airmass and associated trough to form. This lead to last week's infamous warm spell across the southern and southeastern Australia. More recently, this airmass reformed and started its usual pattern of extending south along western WA, drawing in more moisture and developing thick masses of cloud. Additionally, during these last two or three weeks, fronts impacting WA have been relatively weak. All of these factors combined to generate this early, record-breaking warmth.
The heat looks to stick around WA for at least a few days longer. Locations around Perth and the Central Wheatbelt will have another hot day tomorrow, possibly 10 degrees above average for this time of year. It won't be until Wednesday when a cool change will move through, providing respite from the hot weather.
