You know it will be a hot one in Perth when the mercury hits 35 degrees before mid morning. After experiencing 37 degree heat on Friday, Perth is in for another scorcher today. Breezy northeasterly winds are adding more heat to the city, with the temperature steadily climbing throughout the morning. A cooling westerly will arrive early this afternoon, which will see temperatures slowly drop. Showers and storms will develop this afternoon, although more likely in the hills and northern suburbs. Unfortunately, any showers that do develop will be light and generally less than a few millimeters. On average, Perth will experience one day greater than 40 degrees this month (which occurred on Thursday 7th January, when it reached 42 degrees), but there is likely to be between seven-to-eight days greater than 35 degrees during January. By Sunday, temperatures will remain in the low 30’s before a cold front arrives, bringing some real relief. For the start of the working week, temperatures will plummet to the mid-20's with southwesterly winds becoming fresh at times, making it feel even colder than what the mercury suggests. However, the cool weather won't last long, with temperatures rebounding back to the low-30's by Thursday.
