While Perth shivers through its chilliest day in weeks, the rest of the capital cities are being treated to a warm spring day. A vigorous cold front is crossing WA today, blasting Perth with cold and gusty southwesterly winds and showers in its wake. This morning wind gusts nearing 50km/h were recorded in the city, making 12 degrees feel more like nine. Showers are also making it damp, with 11mm in the rain gauge and hail reported around Subiaco. It is only likely to warm to 15 degrees today, five below average, with wind chill continuing to add extra bite to the cold. Meanwhile all of the other state's capital cities should be at least eight degrees warmer today, thanks to hot northerly winds building ahead of the cold front. Adelaide is heading for a top of around 28 degrees and Melbourne 27, while Canberra, Sydney and Brisbane are all looking at maxing out in the mid twenties. Perth residents need not despair though, as a reprieve from the cold is on the way. This afternoon wind and showers will ease as a high pressure ridge builds from the west. It will then warm up over the coming days, reaching 28 degrees by Sunday and 31 for Monday's public holiday. The sunshine will also be out in force providing a glorious weekend, while the cities in the southeast are affected by the cold front.
