Perth can look forward to a cool change after it labours through another scorcher today.

After sweltering through a 40.1C maximum yesterday, the mercury is tipped to reach 38C in the city this afternoon, before dropping cooler for the weekend.

Spectacular lightning shows lit up Perth skies last night as two weather systems clashed over the coast.

The overnight minimum was a balmy 25.2C at 6.30am, the product of warm air flowing in from the northern Wheatbelt and southern Gascoyne.

The storms left 0.2mm of rain in the gauge, snapping a 34-day dry spell for the metropolitan area – the longest for almost two years.

Bureau of Meteorology spokesman Neil Bennett said tomorrow would see cooler air blowing in from the south-west, leading to potential isolated showers and a maximum of just 26C.

“Both the heat and the lightning last night were connected to the same weather phenomenon,” he said.

“We had a surface trough of low pressure off the coast, which interacted with a system in the middle part of the atmosphere as it moved over the coast from the Indian Ocean.

“That’s moving east now, which is why we’ve got blue skies and high temperatures.

“Once that’s moved through Perth we’ll then see cooler air coming in from the south-west.”

He said the cooler weather would continue into the weekend, with forecast maximums of 24C for Saturday and 27C for Sunday.
