A series of cold fronts is set to bring a wintry blast to Western Australia over the next week, with the possibility of a light dusting of snow on Bluff Knoll on Saturday.
The first front will sweep across the south-west corner of the state on Friday morning, pushing through Perth around sunrise and extending into the remainder of the South West Land Division throughout the day.
Bureau of Meteorology forecaster Luke Huntington said that front was fairly typical for winter.
Rain trumps De Kock's unbeaten 92 as England-South Africa series drawn
South Africa opener Quinton de Kock's unbeaten 92 turned out to be in vain as rain scuppered hopes of a result in Sunday's third and final one-day international against England, with the series ending all square at 1-1. The Proteas were 159-2 in the 28th over, with De Kock having struck 92 off just 76 balls, including 13 fours, when rain stopped play for the second time at Headingley. Both sides needed to bat for a minimum of 20 overs for a result to be declared under the Duckworth-Lewis-Stern method for rain-affected white-ball games.
However, he said, cold and gusty winds moving in behind it on Saturday would send temperatures plummeting.
"Some locations through the south are struggling to reach 10 and 12 degrees [Celsius]," he said.
"So, especially through the Great Southern and even into the south-west district, and down on the coast near Albany."
He said there was also a slight chance of snow falling on Bluff Knoll.
"It is potentially cold enough for a light dusting of snow on Saturday morning," he said.
"It's really only a light chance at this stage, and it will be more of a sleet or snow flurry scenario."
Forecasts of snow on Bluff Knoll often attract hikers, but Mr Huntington urged anyone considering that to be cautious of adverse weather conditions.
Mount Barker, near the Stirling Ranges, looks to be one of the coldest locations in the state, with a maximum temperature of only 10 degrees Celsius on Saturday, and a minimum of 4C.
Weather Australia Forecast Sydney Melbourne Brisbane - about to get even worse
South-east Queensland and northern NSW are set to be pummeled by high winds, heavy rain and dangerous surf conditions as a warning said wetter than usual conditions could last until December.The Bureau of Meteorology's climate update on Wednesday confirmed that 'much of Australia' is likely to see 'above average rainfall' until December, due to a negative Indian Ocean Dipole (IOD) phenomenon.
Perth is forecast to reach 16C on Saturday, with a minimum of 9C.
Likely severe weather from Monday to Wednesday
Mr Huntington said the current forecast showed an easing of showers from Saturday afternoon into Sunday.
However, he said, that was expected to be short lived.
He said current models were showing another three back-to-back strong cold fronts would move over the region on Monday, Tuesday and Wednesday.
"Next week is looking pretty interesting," he said.
"There's a high chance of a severe weather warning being issued, with the main risk damaging winds around the southern half of the state."
He said anywhere from Geraldton to parts of the Goldfields and Eucla regions could have severe weather warnings issued.
"It is looking like bigger areas than we would normal see in terms of severe weather," he said.
If that eventuates, it would be the first severe weather warnings of the season, which is later than usual.

Four were from the same family, according to police in the nearby city of Kaushambi.So far this season, more people have died from lightning strikes than rain-related incidents like flooding.
He said there was also likely to be a dangerous swell anywhere from Exmouth to Esperance, which may lead to erosion.
The burst of wintry weather will bring much needed rain to the state.
Perth is currently on track to finish July with average rainfall, after experiencing its second-driest June on record.
Forecasts are currently tipping between 50 and 80 millimetres of rain over the course of the next week.
Grain-growing regions across the South West Land Division are also faring reasonably well this July, with most on track to finish the month with normal rainfall.
Albany is one of the exceptions, currently sitting at about half its usual rainfall for the month, with the coming days likely to bring it closer to 70 per cent.
