A short lived burst of heat will remind those of the record breaking heatwave that affected Perth at the end of 2012.
The city has had a mild start to the year compared to the final week of 2012 which averaged 39.3 degrees. The first four days of the year averaged 28.1, the lowest coming on Friday when it failed to reach 26.
The heat didn't go far though, lingering over the interior and has been drawn back into the southwest of the state. A slow-moving high pressure system in the Bight has allowed northeasterly winds to persist, filtering the hot airmass over the state's capital. On Saturday Perth warmed to 37 degrees which is six above average. Although not as hot as the scorching conditions of yesteryear it was a reminder that summer is not over yet.
On Sunday a trough will deepen and extend south. This will bring the chance of showers and storms along with an increase in cloud. These showers and storms could bring 5-10mm to the city. Perth is expected to reach 35 degrees today, however cloud cover will limit the heating and prevent it from reaching the temperatures recently experienced.
The airmass will warm further on Monday with tops of 36 expected. The trough will linger over the region bringing a risk of showers and storms, with falls of up to 5mm.
Further into the working week it will cool to around average on Tuesday and Wednesday before warming up again leading into the weekend. There are some early indications that Perth could see a return to 40 degrees heat on Saturday.
