Showers and strong winds are sweeping across southwest WA with a strong cold front. The front is stretching as far north as Geraldton and is expected to push rainfall into the Central Wheat Belt district over the next three days. A burst of rainfall arrived early this morning with a low pressure trough ahead of the front. The heaviest rainfall to 9am was recorded in the Lower West district, where Dwellingup received 20mm in three hours between 5am and 8am. This has brought the monthly rainfall total to 185mm, which is 50mm above the September average. Another surge of cold winds on Thursday will bring a renewed burst of heavy showers and the coldest day in weeks for many. So far this month, the average daytime temperature for Perth has been 21.8 degrees, almost two above average. However, Thursday will only reach a top of around 16 degrees, which would be the coldest since the beginning of this month. Strong westerly winds will help to make it feel even colder. Looking further ahead, skies will clear on Friday with a promise of a mostly sunny long weekend.
